RESEARCH

Biological electron transfer reactions are of paramount importance in the metabolism.  My research focuses on the study of the fundamental electron transfer reactions in biology that are relevant to energy and agriculture. The lab uses a variety of different approaches to examine the ecology, physiology, and biochemistry of pathways and reactions that involve oxidation-reduction reactions.

The availability of fixed nitrogen limits global nutrition. We study the process of biological nitrogen fixation that occurs in diverse groups of microorganisms and is an enzymatic process by which atmospheric nitrogen is converted to ammonia.  Through structural and spectroscopic work we study the catalytic mechanism of the enzyme nitrogenase that catalyzes this process. We are also involved in engineering microorganisms to express high levels of the enzymes and excrete ammonia.  This work is aimed in the long term to reduce our dependency on the use of nitrogenous fertilizers in agriculture.

Energy can be stored in H-H, C-H, or N-H bonds and fuel compounds having these bonds can be produced in all forms of life through electron transfer reactions.  We are examining the fundamentals of biological electron reactions as it relates to control of electron flow in organisms to enhance biofuel production.
