Research Summary: 
Bacterial Pathogenesis
Research Detail: 

Dr. Pepperell's research focuses on the ecology and evolution of human pathogens. Infectious diseases differ from other human diseases in that they involve the interplay between distinct species with mostly antagonistic goals. Many of the techniques developed in the field of evolutionary biology are well suited to the study of these dynamic systems and are promising tools in the search for improved methods to control and treat infectious diseases.
