The U.S. Department of Defense (DoD) awarded four UConn scientists with high-profile grants to fund the acquisition of technology to bolster their research capabilities.

The highly competitive Defense University Research Instrumentation Program (DURIP), offered by the Air Force Office of Scientific Research (AFOSR), the Army Research Office (ARO), and the Office of Naval Research (ONR), funds cutting-edge research projects with potential to assist national defense.

Lithium-ion (Li-ion) batteries are one of the most common rechargeable energy storage technologies on the market. As a rule, they are quite safe under normal operating conditions, powerful, and scalable, from smartphones to electric cars. But given the number of Li-ion batteries produced around the world, their relatively small failure rate has still resulted in some high-profile stories of Li-ion batteries going into thermal runaway – an event when a battery catches fire, explodes, and releases toxic gases.

IMS member Naba Karan, an assistant research professor at the Center for Clean Energy Engineering (C2E2) in the School of Engineering, isn’t surprised.

“You can think of them as bombs,” he says, noting the high quantity of chemical energy contained within Li-ion batteries. And he’s looking to blow them up—on purpose.

With funds from the Office of Naval Research, Karan is constructing a facility at UConn that will explode the batteries in a controlled environment to determine critical safety parameters needed for designing advanced engineering protocols to mitigate thermal runaway events. In a military context, this information will help operators of machinery that depend on these high-powered batteries, such as submarines, determine when internal battery temperatures are exceeding safety thresholds. Most crucially, it will allow them to avoid catastrophic failure by diverting some of this heat.

The equipment will be able to analyze thermal characteristics of all types of energy storage technologies, not only Li-Ion batteries. Since it will be one of the only such facilities in the northeast region, Karan anticipates a high degree of interest and collaboration from other universities and companies looking into studying the safety characteristics of existing and emerging battery chemistries.

IMS Welcomes Mihai “Mishu” Duduta

Dr. Mihai Duduta
Dr. Mihai Duduta’s research has the potential to change the future of robotics.

Mihai “Mishu” Duduta has joined the Department of Mechanical Engineering with an appointment in the Institute of Materials Science (IMS).  Having earned his B.S. from MIT, he completed his M.S. and Ph.D. at Harvard University.  Following the completion of his Ph.D., Duduta joined the faculty of the Department of Mechanical and Industrial Engineering at the University of Toronto as an assistant professor.  He is a recipient of the Banting Foundation Discovery Award for 2022 for his research on “Smart Micro-catheters Based on Electro-mechanical Artificial Muscles.”

At the heart of his research “Mishu” (as Duduta prefers to be called) is focused on the science of soft robotics, novel materials, and energy storage.  He seeks to “invent new ways to store energy and deliver power that bring new robotic capabilities.”

IMS News reached out to Dr. Duduta to welcome him and learn more about him and his research.

Your research focus includes novel materials, soft robotics, and energy storage.  All of these are at the cutting edge of future technology.  What led you to pursue this field of science?

I have always been fascinated by energy, and by materials that can act as transducers, effectively transforming one type of energy into another, for example chemical energy stored in covalent bonds of a fuel, to thermal energy, or heat by burning said fuel. I see Robotics as the next area of innovation for energy storage, conversion and harvesting.

You have said that in order for robots to interact more closely with people they must be more compliant, or flexible.  How can the combination of materials, soft robotics, and energy storage achieve this goal and what do you see as the future implications as the science advances?

As machines become smaller or softer, we’ll need to invent new materials and mechanisms for actuation, sensing and computation. The end goal is to replicate nature as closely as possible, in an engineered system. If we have artificial muscles that can effectively replace natural ones, and run as efficiently for long periods of time, we can radically change almost all segments of the economy: from healthcare, to agriculture, manufacturing and beyond.

We are happy to welcome you to UConn IMS.  How did you become interested in UConn and how will you contribute to student success, a key priority for the University?

UConn has a great location, outstanding students, talented faculty, and fantastic infrastructure.  My goal is to train students to be more capable scientists and engineers, but also to develop a strong grasp of how to communicate science effectively, as well as gain an understanding of where their work can bring societal value.

Richard Parnas on FOG, Biofuels, and Wastewater Management

Professor Emeritus of Chemical and Biomolecular Engineering, Richard Parnas, has been working on solutions to the oily waste we humans produce on a daily basis.  He has been on a journey to convert that waste into usable energy.  This quest has led to the patent of proprietary technology and the formation of REA Resources Recovery Services, a company he co-founded.  Along with his partners in the company and in partnership with UConn, Dr. Parnas set about to convert FOG (Fat, Oil, Grease) into biodiesel for the benefit of municipalities in the state.

In 2019, REA contracted with the City of Danbury to build a FOG to biodiesel processing facility at the city’s wastewater treatment plant.  That project has entered the construction phase and Parnas, REA, and UConn are now looking forward to the day the facility converts its first oily waste into usable biodiesel.  IMS News reached out to Dr. Parnas about his research, the Danbury project, and the future of wastewater management.

Richard Parnas
Dr. Richard Parnas

You have been researching and developing methods to convert FOG (Fat, Oil, Grease) into biodiesel fuel since 2006.  When did you first become interested in biofuels and what about biodiesel, in particular, led you down your current path?

I’ve been interested in biofuels, and green processing and green materials in general, for many years before coming to UConn. One of the important motivations for joining UConn was to participate in the development of the green economy. An undergraduate helped get me started working on biodiesel in the summer of 2007 by simply requesting my help to set up a biodiesel synthesis reaction in a fume hood.

When you became Director of the Biofuel Consortium here at UConn, you moved the bar from six gallons of biofuel produced over the course of a year to over 50 gallons continual production daily less than three years later.  When did you realize the scale at which you might be able to convert FOG into biodiesel?  What were the obstacles you faced and how were they overcome?

We used the yellow grease from UConn cafeterias to make biodiesel at that time, and the scale of operations was determined by the yellow grease production rate from the cafeterias. As a Chemical Engineer, my goal is always to maximize the use of available raw materials, and waste as small a fraction of that raw material as possible. Shortly after we started the Biofuel Consortium, we polled the various food service establishments at UConn to determine the yellow grease availability, and found it to be over 100 gallons per week. We then designed, built and installed a 50 gallon batch system, and produced 2 or 3 of the 50 gallon batches each week.

There were a number of obstacles. Production at that scale is not a typical academic activity so we faced skepticism from the facilities folks that ran the fuel depot for the buses. They asked if our fuel would be any good and how we would prove it to them, so we had to set up testing capability. Our testing was developed and run by Prof. James Stuart, an analytical chemist. Prof. Stuart and I received a grant of over $600,000 dollars to set up a biodiesel fuel quality testing facility in the Center for Environmental Science and Engineering (CESE) to test our biodiesel and the biodiesel produced by private companies. We also faced skepticism from the UConn administration since we were operating at a much larger scale than is typical. Safety concerns are important when conducting such operations with students who are just learning how to handle chemicals.

REA Resource Recovery Systems, a company which you co-founded and worked in collaboration with UConn to patent exclusive technology, has entered Phase 4 of itsREA Logo planned development of a 5000 square foot facility in Danbury that will turn FOG into biofuel.  How important is wastewater management for municipalities and what will be the benefits for the City of Danbury once the facility is online.

I joined my two partners, Al Barbarotta and Eric Metz, to found REA at the end of 2017. The UConn patents were already in place for a piece of core technology called a counterflow multi-phase reactor that plays a key role in both the chemical conversion and in the product purification. Prof. Nicholas Leadbeatter from Chemistry is a co-inventor with me on that reactor, along with two undergraduate students. Beginning in 2015, I started working with a very low grade feedstock called brown grease, which is much harder to process than the yellow grease we had been working with earlier. Every single wastewater treatment plant in the world has a brown grease management and disposal problem, and every municipality has a wastewater management problem. In much of the world, wastewater management is required by law and heavily regulated to ensure that effluent meets standards for discharge into rivers and oceans.

Here in CT, the brown grease problem was handled by DEEP many years ago by mandating that certain wastewater treatment plants in the state become FOG receiving stations. Brown grease is the component of FOG that causes all the problems. These FOG receiving stations were given a small set of choices as to how to dispose of the brown grease they received, such as by landfilling or incineration. All the choices cost money and vectored pollution into the air, the land, or the water.

Danbury was mandated to become a FOG receiving facility several years ago, and undertook a general plant upgrade project to build a FOG receiving facility and then dispose of the FOG using biodigesters. When that disposal pathway became too difficult due to high cost they sought alternatives. REA was ready at that time to provide the alternative of converting the brown grease into a salable product, biodiesel. This solution provides two benefits to Danbury, an environmentally excellent disposal method and a source of revenue. REA estimates that the revenue will offset the cost of the project in Danbury in about 7 years, and that the payback period will be significantly shorter in larger facilities.

It has been 15 years since you undertook this journey of making biodiesel a viable alternative energy source.  How does it feel to see your years of work coming to fruition with the Danbury project?

It feels terrifying because we have not yet started up the Danbury plant. When we successfully start Danbury, the relief and satisfaction will be enormous. Until then, for the next few months, everyone associated with the project is working very hard to finish the installation.

Since retiring in 2020, you appear to be just as active in your pursuit of science.  What continues to drive you and is there anything you miss now that you have retired?

I am driven by the desire to see this biodiesel project through to completion and by the desire to play some small role in mitigating the unfolding climate catastrophe. When I started at UConn I was surprised that the academic definition of project completion is a final report. As an engineer, that did not seem to be enough because most reports are ignored and forgotten. Sometimes I miss the teaching aspect of working at UConn, but I think I most miss the camaraderie of my colleagues, with whom I have much less time now than I used to.

Yu Lei Invents Low-Abundance Biomarker Detection Platform for Early Diagnosis

from UConn Today

Dr. Yu Lei
Dr. Yu Lei

Yu Lei, professor of chemical and biomolecular engineering, has invented a new platform that can perform high-sensitivity readings for a variety of disease biomarkers.

In the 1970s, scientists invented the enzyme-linked immunosorbent assay (ELISA). Since then, ELISA has been the standard for detecting biomarkers.

Biomarkers are molecules present in the body that indicate the presence or severity of a disease. For example, autoantibodies can help detect autoimmune diseases, or a peptide known as amyloid-β can indicate Alzheimer’s disease.

One of the major limitations for ELISA is that if there is a low concentration of the molecule of interest, it cannot detect it. Lei’s invention addresses this problem by adding two amplification steps to ELISA’s process.

“We wanted to bridge the need for ultra-sensitivity, and also compatibility with the existing plate-based platform,” Lei says.

ELISA works using a “sandwich” of two antibodies specifically designed to capture/detect the biomarker of interest between them. One of these antibodies has an enzyme attached to it that will produce a readable signal when it encounters the substrate.

Lei introduced a two-step amplification to the ELISA reaction. Lei first added a tyramide signal amplification (TSA) process to amplify the signal of a low abundance biomarker. In Lei’s platform, the TSA step anchors numerous biotins onto the immunocomplexes. Lei then introduced the reporter enzyme alkaline phosphate (ALP) conjugated with streptavidin, which attaches to the biotins through the strong interaction between biotin and streptavidin.

Dr. Lei's Research

Lei added an ELFA-saturated ELFP substrate that ALP breaks down to produce a fluorescent signal. These molecules that precipitate through the system to form a readable layer consisting of fluorescent needles that a microscope captures as a series of images and counts. This fluorescent microneedle count corresponds to how much of the biomarker is in the sample.

“That’s the beauty of the system using ELFA-saturated ELFP substrate and counting-based method, we achieved rapid detection and at the same time no matter your initial number of target molecules their precipitating time is starting from the same point,” Lei says.

Lei successfully demonstrated that his process was able to achieve a resolution of 50 to 60 picograms per milliliter. This is about 20 times more sensitive than traditional ELISA using the same commercial ELISA kit.

Lei published his findings in the March issue of Analytica Chimica Acta.

This advancement could be extremely useful for early-stage detection of diseases and treatment.

“A lot of disease detection occurs when symptoms are already onset,” Lei says. “That biomarker concentration is already very high. So then, if we can detect at a very low concentration, we can capture the earliest stage and treatment may be more effective.”

Lei says the next step for this technology is to smoothly integrate it into conventional plate-based ELISA systems. This would allow the process, which currently takes about four hours for low-abundance biomarker detection, to be much faster by using advanced imaging systems.

Designing a Lighter, Denser Fuel Cell

from UConn Today

Fuel Cells
Fuel cells are a promising direction for cleaner energy, and a team of UConn researchers is working to improve their design (Adobe Stock).

Fuel cell technology is continuously evolving as renewable energy and alternate energy sources become an increasingly important means of reducing global dependence on fossil fuels. Planar fuel cells, a prevalent design, can be bulky, have compression issues, and uneven current distribution. Other drawbacks include problems with reactant gas transport, excess water removal, and fabrication challenges associated with their design.

A team of UConn researchers led by Jasna Jankovic, an assistant professor in the Department of Materials Science and Engineering in the School of Engineering, has devised a novel design for a tubular polymer electrolyte membrane (PEM) fuel cell that addresses those shortcomings and improves on existing tubular PEM fuel cell designs, most of which take a planar PEM fuel cell and curl it into a cylinder.

Jankovic and two grad students, Sara Pedram and Sean Small, took a more holistic approach that rethinks tubular fuel cell design from the ground up. Their disruptive, patent-pending concept could potentially have nearly twice the energy density of other tubular PEM fuel cells, be 50 percent lighter, have a replaceable inner electrode and electrolyte (if liquid), a leak-proof configuration, and require fewer precious metals.

That’s a big deal, says Michael Invernale, a senior licensing manager at UConn’s Technology Commercialization Services (TCS) working with Jankovic to bring the concept to market. Much of the effort to improve fuel cell design, he says, has focused on the end user instead of the greater good.

“A fuel cell with refillable components is a kind of solution that does that,” says Invernale.  “An airline relying on this technology would have more incentive to rebuild a component. Right now, it might be cheaper to replace the whole unit. That’s really where this design shines. The features of the design are green and sustainable and renewable.”

Fuel cells are essentially refuelable electrochemical power generation devices that combine hydrogen and oxygen to generate electricity, heat, and water. Each type is classified primarily by the kind of electrolyte it uses. Planar fuel cells are constructed using sandwich-like stacks of large, rectangular flow field plates made of graphite or metal, which account for about 80 percent of their weight and 40 percent of their cost. UConn’s design uses a single tube-shaped flow field that reduces its weight by half.

Jasna Jankovic
Dr. Jasna Jankovic

The concept is still in discovery and has I-Corps and Partnership for Innovation (PFI) funding from the National Science Foundation (NSF). The program was created to spur the translation of fundamental research to the marketplace, encourage collaboration between academia and industry, and train NSF-funded faculty, students, and other researchers in innovation and entrepreneurship skills.

Participating research teams have the opportunity to interview potential customers to learn more about their needs. Jankovic and her team conducted some 60 interviews during a UConn Accelerator program in early 2022 that helped them size up the market and answer important questions about whether or not to start a longer process, make the product themselves, or license the technology to another company.

“It was very useful to get feedback and guidance from people in industry” Jankovic says.

Jankovic led the team as PI, with Pedram and Small, acting as Entrepreneurial Lead and Co-Lead respectively. Lenard Bonville, the team’s industrial mentor, will support the team with his decades of industrial experience. The team will conduct another set of 100 interviews with industry to discover the market for their product and get guidance on its final design. NSF-Partnership for Innovation (PFI) funding will then be used to develop a prototype and pursue commercialization.

Fuel cells have a wide range of applications, from powering  homes and businesses, to keeping critical facilities like hospitals, grocery stores, and data centers up and running, and moving a variety of vehicles, including cars, buses, trucks, forklifts, trains, and more. Jankovic’s team is working toward obtaining a full patent on their design and thoroughly testing the concept. In the short term, they are focused on commercializing the technology and attracting potential partners.

Jankovic envisions creating a fuel cell roughly the size of a AA battery however, as a scalable and modular technology, it could be scaled-up to any practical size. The cylindrical shape would allow for more fuel cells to occupy the same amount of space as those in use now and be cheaper to manufacture, Invernale said. Jankovic views her fuel cell design as a replacement for Lithium-Ion batteries.

Jankovic said her seven years in industry before coming to UConn convinced her there was a need in the market for a new and better fuel cell design.

“From that experience, I knew that planar fuel cells had a few issues,” she says. “I kept asking around, and I said, ‘let’s do it and find out yes or no.”

Dr. Cato Laurencin Publishes Breakthrough Report on Rotator Cuff Regeneration Treatment

from UConn Today

Cato Laurencin
Dr. Cato Laurencin

A new way to regenerate muscle could help repair the damaged shoulders of millions of people every year. The technique uses advanced materials to encourage muscle growth in rotator cuff muscles. Dr. Cato Laurencin and his team reported the findings in the Proceedings of the National Academy of Sciences (PNAS) August 8th issue.

Tears of the major tendons in the shoulder joint, commonly called the rotator cuff, are common injuries in adults. Advances in surgery have made ever better rotator cuff repairs possible. But failure rates with surgery can be high.  Now, a team of researchers from the UConn School of Medicine led by Laurencin, a surgeon, engineer and scientist, reports that a graphene/polymer matrix embedded into shoulder muscle can prevent re-tear injuries.

“Most repairs focus on the tendon,” and how to reattach it to the bone most effectively, Laurencin says. “But the real problem is that the muscle degenerates and accumulates fat. With a tear, the muscle shrinks, and the body grows fat in that area instead. When the tendon and muscle are finally reattached surgically to the shoulder bone, the weakened muscle can’t handle normal stresses and the area can be re-injured again.

Dr. Laurencin along with graduate student Nikoo Shemshaki worked with other UConn Connecticut Convergence Institute researchers to develop a polymer mesh infused with nanoplatelets of graphene. When they used it to repair the shoulders of rats who had chronic rotator cuff tears with muscle atrophy, the muscle grew back. When they tried growing muscle on the mesh in a petri dish in the lab, they found the material seemed to encourage the growth of myotubes, precursors of muscle, and discourage the formation of fat.

“This is really a potential breakthrough treatment for tears of the rotator cuff. It addresses the real problem: muscle degeneration and fat accumulation,” Laurencin says.

The next step in their work is studying the matrix in a large animal. The team looks forward to developing the technology in humans.

This work was funded by NIH National Institute of Arthritis and Musculoskeletal and Skin Diseases Grant No. DP1AR068147 and National Science Foundation Emerging Frontiers in Research and Innovation Grant No. 1332329.

Department of Energy Early Career Award Recipient Yuanyuan Zhu

Yuanyuan Zhu
Dr. Yuanyuan Zhu is the only Connecticut recipient of the DOE Early Career Award for 2022.

Established in 2010, the DOE Office of Science Early Career Research Program supports the individual research programs of outstanding scientists early in their careers and stimulates research careers in the disciplines supported by the DOE Office of Science: Advanced Scientific Computing Research (ASCR), Biological and Environmental Research (BER), Basic Energy Sciences (BES), Fusion Energy Sciences (FES), High Energy Physics (HEP), Isotope R&D and Production (IP), and Nuclear Physics (NP).

Among the 83 university and DOE national lab researchers announced as recipients of the award for 2022, Assistant Professor of Materials Science and Engineering Yuanyuan Zhu is the only Connecticut researcher to receive the honor.  IMS News asked Dr. Zhu about her research and the award.

In 2019, you were appointed Director of the UConn DENSsolutions InToEM Center for in-situ TEM research at IPB Tech Park.  You have since had papers published related to the research the Center is conducting.  As we are seeing more and more evidence of the effects of climate change, how do you hope your research at the InToEM Center will assist in solving some of the problems we are now dealing with?

Yes, we have published a couple of papers since 2019 using the in-situ environmental TEM gas cell. Here you can find our full publications: https://scholar.google.com/citations?hl=en&user=HlDqamcAAAAJ&view_op=list_works&sortby=pubdate .

It’s a coincidence that the DENSsolutions’ ETEM gas cell system is named as “Climate”, because it involves gas environment for chemical reactions in a microscope. Another example is their liquid cell system, which is called “Stream” simply because the reaction stimuli involved.

There are many materials researches related to energy and environment, including climate change, that can benefit from the in-situ ETEM research. One immediate example is heterogeneous catalysis used for natural gas conversion and H2 production. And the fusion energy materials research funded by the DOE ECA is another good example.

Congratulations on receiving the Department of Energy’s Early Career Award for 2022.  What are your hopes for your research on Understanding Thermal Oxidation of Tungsten and the Impact to Radiation Under Fusion Extremes?

Fusion energy holds great promise for replacing fossil fuels for 24/7 baseload electrical power. We are excited that the DOE Early Career Award will fund our in-situ ETEM study to directly address a well-known fusion safety hazard concerning aggressive high-temperature oxidation of plasma-facing material tungsten. We hope to gain fundamental understanding of tungsten degradation in case of air-ingress scenarios that could inform the best strategy for responding to accidents, and could guide the design of advanced W-based materials that better preserve divertor integrity for even more demanding DEMO fusion extremes. Simply put it, we want to make the operation of fusion energy systems safer and more reliable.

You have several Ph.D. candidates under your advisement.  How do you hope to influence these young scientists?

Our research group provides a welcoming, supportive and inclusive working environment to drive personal success for each Ph.D. researcher. Through the first-hand work on such research projects closely to clean energy and sustainability, I believe our Ph.D. students will gain confidence and skills in research and also develop a solid sense of social responsibility.

We are seeing many more women represented in STEM.  What advice would you give to young women who may be considering a career in science, technology, engineering and mathematics?

We need everyone in STEM, and anything is possible if one follows his/her/their passion. Research is fun but progress is built on failure and resilience.

 

Cato T. Laurencin Named 2023 Priestley Medalist

from UConn Today

Dr. Cato Laurencin
Scientist and engineer, Dr. Cato T. Laurencin, has been honored for seminal and lasting research benefiting humankind.

Cato T. Laurencin, the University Professor and Albert and Wilda Van Dusen Distinguished Endowed Professor at the University of Connecticut will receive the 2023 Priestley Medal, the highest honor of the American Chemical Society.

He is recognized as the leading international figure in polymeric biomaterials chemistry and engineering who has made extraordinary scientific contributions, while at the same time he has had profound contributions to improving human health through the results of his work. While trained in polymeric chemistry, Laurencin’s overall training is broad and interdisciplinary. He received his B.S.E. in Chemical Engineering from Princeton University. He received his Ph.D. in Biochemical Engineering/Biotechnology from the Massachusetts Institute of Technology and simultaneously received his M.D., Magna Cum Laude from the Harvard Medical School. He then joined the faculty of the Massachusetts Institute of Technology and opened a polymer chemistry research laboratory. At the same time he trained and became a board certified orthopaedic surgeon.

Dr. Laurencin produced seminal work on polymeric nanofiber chemistry technology for biomedical purposes, heralding the new field. He pioneered the understanding and development of polymer-ceramic systems for bone regeneration for which the American Institute of Chemical Engineers named him one of the 100 engineers of the modern era at its Centennial celebration. In a three decade collaboration with Professor Harry Allcock at Penn State, Laurencin worked in the development of polyphosphazenes for biomedical purposes. Dr. Laurencin has had breakthrough achievements in the areas of materials chemistry and engineering of soft tissue implants for regeneration of tissue including the development of the Laurencin-Cooper (LC) Ligament for anterior cruciate ligament regeneration (knee). The development of the LC Ligament was highlighted by National Geographic Magazine in its “100 Discoveries that Changed the World” edition.

In his latest work, Dr. Laurencin has pioneered a new field, Regenerative Engineering, described as the Convergence of areas such as nanomaterials science and chemistry. His work has described the chemistry of signaling molecules for tissue regeneration and he published this work in Plos One (https://doi.org/10.1371/journal.pone.01016272014). He demonstrated the ability these molecules in combination with polymeric materials chemistry to induce tissue regeneration.  In his most recent work he has used principles of polymer chemistry to create cell-like structures. This has allowed the creation of what is being considered a new class of stem cells: synthetic artificial stem cells (SASC). The work was recently published in the Proceedings of the National Academy of Sciences.

The impact of the new field has become clear. The NIH Awarded him their highest and most prestigious award, the NIH Director’s Pioneer Award for his field of Regenerative Engineering. The NSF awarded him their most transformative grant, the Emerging Frontiers in Research and Innovation Grant (EFRI) for Regenerative Engineering. Dr. Laurencin is the Editor-in-Chief of Regenerative Engineering and Translational Medicine, a journal published by Springer Nature. He is the Founder of the Regenerative Engineering Society (now a community of the American Institute of Chemical Engineers). The American Institute of Chemical Engineers Foundation created and endowed the Cato T. Laurencin Regenerative Engineering Founder’s Award honoring Dr. Laurencin’s work and legacy in this new field. He is the first individual to receive highest distinctions across science, engineering, medicine and technology for this work. In science, he received the Philip Hauge Abelson Prize from the American Association for the Advancement of Science awarded “for signal contributions to the advancement of science in the United States”.  He was awarded both the highest/oldest honor of the National Academy of Engineering (the Simon Ramo Founders Award) and one of highest/oldest honors of the National Academy of Medicine (the Walsh McDermott Prize). And he received the National Medal of Technology and Innovation, our nation’s highest for technological achievement in ceremonies at the White House.  Most recently, he received the 2021 Spingarn Medal given for the “highest or noblest achievement by a living African American during the preceding year or years in any honorable field.”  The highest award of the NAACP, they stated “his exceptional career has made him the foremost engineer-physician-scientist in the world.”

Dr. Laurencin has also profoundly contributed to mentoring and fostering diversity. He has been responsible for the development of a generation of underrepresented engineers and scientists. In receiving the American Association for the Advancement of Science Mentor Award, it was noted that the majority of African-American faculty in bioengineering had been mentored by Laurencin. For his work in mentoring, he was honored by President Barack Obama with the Presidential Award for Excellence in Science, Math and Engineering Mentoring. Remarkably, he received the 2021 Hoover Medal given jointly by the American Institute of Chemical Engineers, the American Society of Mechanical Engineers (ASME), the American Society of Civil Engineers (ASCE), the American Institute of Mining, Metallurgical and Petroleum Engineers (AIME) and the Institute of Electrical and Electronics Engineers (IEEE), The purpose of the medal is “to recognize great, unselfish, non-technical services by engineers to humanity.” Dr. Laurencin’s extraordinary commitment to inclusion, equity and fairness along with his legendary work in mentoring lead to his selection.

Dr. Laurencin’s life, career and philosophy are contained in his recently published biography entitled “Success is What You Leave Behind,” published by Elsevier.
