Elizabeth A McGraw

Elizabeth "Beth" McGraw is a biologist and entomologist. She is a professor of entomology and head of the Department of Biology at the Pennsylvania State University. Her research focuses on mosquito vector biology, Wolbachia–host interactions, and vector-borne diseases. She was elected a Fellow of the American Society for Microbiology.

Early life and education McGraw received a Bachelor of Science with honours in biology from the University of Michigan–Flint in 1993. She completed a Ph.D. in biology at the Pennsylvania State University in 1998.

Career Following her doctoral studies, McGraw held postdoctoral appointments at Yale School of Medicine from 1999 to 2001 and at the University of Queensland from 2001 to 2002. In 2002, McGraw joined the University of Queensland as an assistant professor in genetics.

McGraw joined the Monash University School of Biological Sciences in 2011 as a Larkins Fellow. She became a professor in 2017.

In 2017, McGraw joined Pennsylvania State University as a professor of entomology. In 2021, she became head of the university's Department of Biology.

She has extensively studied Wolbachia in mosquitoes, particularly its role in limiting the replication of pathogens and its potential use in biological control strategies for mosquito-borne diseases.

McGraw has also studied the genetics and ecology of mosquito-borne disease transmission, including dengue and chikungunya. Her work has addressed how temperature, thermal stress, mosquito population differences, and viral adaptation may influence mosquito competence and the geographic distribution of vector-borne diseases. Her research has examined the ability of Wolbachia to inhibit viral replication in mosquitoes. She has also investigated whether dengue virus can develop resistance to Wolbachia-mediated blocking and how viral exposure to Wolbachia affects infection and replication in mosquito cells.

At Pennsylvania State University, McGraw's research has also included pathogen surveillance through wastewater monitoring. This work has examined the use of wastewater data to track respiratory and enteric viruses in university and community settings.
