Public Health Program Director & Professor
B.S. in Biology, Roanoke College
Ph.D in Molecular Biology, University of Virginia
Postdoctoral research - Laboratory of Dr. Lucy Shapiro, Developmental Biology, Stanford University
My current research is focused on genomic analysis of the acquisition, regulation, and evolution of antibiotic resistance in commensal and pathogenic E. coli, a common gut bacterium in humans. Antibiotic resistance is a growing public health problem, and understanding how potential pathogens acquire resistance is of biological, epidemiological, and medical significance. During the 2014-15 academic year I was on sabbatical leave working in the laboratory of Dr. Lee Riley, Division of Infectious Diseases, UC Berkeley School of Public Health.
