My teaching philosophy is centered on the premise that everyone should have a basic knowledge of science in order to make connections between different aspects of biology and everyday life. My classroom is a place for students to foster new ideas and to piece together scientific concepts in order to understand broad concepts and encourage lifelong learning in the sciences. Microbiology and virology are my areas of expertise and my research focuses on factors impacting the transmission of mosquito-borne viruses.

I study arthropod-borne viruses (arboviruses) and the mosquitoes that transmit arboviruses. My research interests focus on understanding biotic and abiotic factors that influence transmission dynamics of mosquito-borne viruses such as dengue virus, West Nile virus, and Zika virus.  Typically, the best way to control these viruses is to prevent transmission by a mosquito host; however, this is no simple task.  Recently, it was discovered that bacteria and fungi in the mosquito midgut can actually limit transmission of some arboviruses and exploiting this has become one proposed method for limiting virus transmission thus decreasing disease burden.  Problematically, little is understood about the complex relationship between the mosquito, the virus, and the community of bacteria harbored by the mosquito.
