Overview of Focus

My research program is directed at exploring and understanding the factors that influence the emergence and persistence of emerging and re-emerging diseases at the human- wildlife interface. My program embraces a systems biology approach to ecosystem health integrated with public health, beginning within host - pathogen dynamics and extending to the rural livelihoods of communities living with wildlife, including the impact on ecosystem function and local communities themselves.

Courses Taught

molecular lab

Dr. Alexander has established a field laboratory in her study site in Northern Botswana which has both molecular genetics and bacteriological investigations capacity-the first of its kind in the region. The focus of her work is directed at understanding disease transmission dynamics at the human-wildlife interface. In Botswana, Risa Pesapane, previous graduate student, processes DNA from bacteria cultured from banded mongoose fecal samples.
