About me
My main research focus is in ecology and evolution of avian parasitic diseases. Since 1999 I have been developing a research program that addresses the evolution and ecology of host-parasite interactions, with a primary emphasis on avian blood parasites. The field encompasses many aspects of biology including ecology, evolution, parasitology and conservation genetics. In collaboration with researchers at the Center for Tropical Research at UCLA, JPL/NASA, UC Davis, and the Institute of Ecology at Vilnius University, Lithuania, I study the effects of deforestation on the spread of infectious diseases in African rainforest birds.
