Graduate Students

Talia Wong, VMD, is a PhD student in the Epidemiology Graduate Group at UC Davis. Her work is focused on developing a vector control strategy for the primary vectors of West Nile virus in California, Culex tarsalis and Culex pipiens. Talia earned her VMD from the University of Pennsylvania and is an ACVP board-certified veterinary pathologist.

Karen Click, MPH, is a PhD student in the Epidemiology Graduate Group at UC Davis. She obtained her MPH from UC Berkeley, where she studied how land cover and drought affect Valley fever rates and seasonal patterns in California. Her dissertation will focus on the impacts of climate and health equity on West Nile virus transmission.

Sarah Abusaa, MPH, is a PhD student in the Epidemiology Graduate Group at UC Davis. Her research focuses on predicting the spread of the invasive mosquitoes, Aedes aegypti and Aedes albopictus. She obtained her MPH from Yale University, where she studied factors affecting household-level variation in the abundance of container-breeding mosquitoes on the island of Montserrat.
