Research Interests
Research in my laboratory is dedicated to understanding the basis of infectious disease at molecular and cellular levels. We focus on mechanisms by which virulence factors produced by pathogenic microbes interact with host cell targets and thereby modulate host cell behavior during infection. We study these interactions in structural detail (i.e., at the level of atomic resolution through X-ray crystallography) in order to carry out precise biochemical, genetic, and cell biological experiments aimed at elucidating the mechanism of action of bacterial virulence factors in their cellular and organismal contexts.
