overview
My primary area of interest is in molecular epidemiology and in particular investigating selection pressures driving bacterial pathogen populations at the interface between humans, agricultural animals, and the environment. I use molecular techniques such as next generation sequencing to investigate how bacterial populations change in response to selection pressures. One example is the unintended consequences of antimicrobial use on E. coli and Salmonella populations in cattle and swine and their environments. I am also interested in using whole genome sequencing to compare bacterial populations and improve upon current typing techniques.
