Steven A. Williams earned his Ph.D. from the University of California, Davis.

My laboratory focuses on research designed to elucidate the molecular biology of the parasites that cause elephantiasis and African river blindness. Most of our research relates in one way or another to the goal of eliminating these diseases that afflict 200 million people worldwide. We also study animal parasites that infect endangered wildlife.


The following areas of research are actively ongoing in my laboratory:
