Dr. Ezenwa has a joint appointment in the Odum School of Ecology and the Department of Infectious Diseases, College of Veterinary Medicine.

Education

Ph.D. - Princeton University

B. A. - Rice University

 

Research Interests

  • Ecology and evolution of infectious diseases
  • Behavioral ecology
  • Host physiology and behavior as drivers of variation in parasite susceptibility and exposure
  • Links between biodiversity loss and infectious disease

Research Projects

Effects of host behavior on parasitism and the role of parasites in the evolution of host behavior; co-infection and its consequences for patterns of disease at multiple scales; community ecology of infectious disease from the host and parasite perspectives. My lab is currently addressing these questions in ungulate host systems in both the western U.S. and sub-saharan Africa.
