Elizabeth McGraw

McGraw was an undergraduate biology student at the University of Michigan.^[when?] She moved to Pennsylvania State University where she studied the evolution of virulence genes in human pathogens and was awarded a PhD in 1998.^[6]

After her PhD, she joined Yale University for her postdoctoral research, where she studied the Wolbachia insect system. She was particularly interested in being able to ask questions about the evolution of mutualism. She moved to the University of Queensland as a postdoctoral researcher.

McGraw was appointed to the faculty at the University of Queensland, then moved to Monash University as a Larkins Fellow in 2011, where she studied how bacteria affect host biology and how insects invest in response to a symbiont.^[7] She has extensively studied the endosymbiont Wolbachia. Wolbachia prevents harmful pathogens replicating inside mosquitos, which may offer hope for biocontrol against mosquito-borne diseases.^[8] Her research showed that when Wolbachia was inside mosquitoes it could prevent viruses from replicating.^[9] She showed that Dengue virus could not become resistant to Wolbachia, and that Dengue viruses grown with Wolbachia were less effective at infecting mosquito cells and were less able to replicate.^[9][10]

In 2017, McGraw joined Pennsylvania State University as a professor in entomology.^[11]

McGraw was elected Fellow of the American Society for Microbiology in 2023.^[8]
