Personal Statement:

My background in medical and molecular entomology and vector biology has led to my role as a principal investigator on many research projects on vector-borne diseases (particularly dengue, Chagas and West Nile virus), instructor of graduate courses on vector biology and ecology at the Department of Tropical Medicine at the Tulane School of Public Health and Tropical Medicine, director of the training program in vector-borne diseases at Tulane, and director of Tulane's Vector-Borne Infectious Diseases Initiative.  My research interests include the ecology of arbovirus transmission, host-pathogen co-evolution, development of novel vector control strategies and tools, and examining the effects of vector-borne pathogen infection on human pregnancy outcomes.  I have mentored more than 120 graduate (MSPH and PhD) students and numerous post-doctoral researchers.

Research Interests:

Ecology of arbovirus transmission; host-pathogen coevolution; development of novel vector control strategies and tools; effect of arbovirus infection on human pregnancy outcome; medical entomology; novel vector control methods
