  • NIH Postdoctoral Fellow, University of California at Berkeley, 1977-80
  • Ph.D., Boston University, 1977
  • B.S., Memphis State University, 1972

Research Focus

  • Solar energy capture and conversion in natural and synthetic systems
  • Energy and electron transfer in photosynthesis
  • Structure and function of biological pigments and pigment-protein complexes
  • The use of steady-state and ultrafast time-resolved optical spectroscopy and electron paramagnetic resonance as probes of the mechanisms of biological photoprocesses
  • How plants and algae adapt to varying environmental conditions and deal with high-light stress
