Enzyme structure, function and evolution; comparative biochemistry

Research and Professional Interests:

Over the years I have been interested in cellular energy homeostasis in animals with emphasis on the evolution and physiological roles of a family of enzymes called the phosphagen (guanidino) kinases. These enzymes include the more familiar creatine kinase which plays a critical role in mitigating spatial and temporal mismatches in ATP supply and demand in certain cell types. Our work has benefited from substantive collaborations with a structural biology group as well as several molecular evolution labs.
