  • McGraw can comment on the biology and evolution of viruses, including the coronavirus outbreak.
  • Her research methods involve quantitative genetic, experimental evolution, genomic and molecular biology approaches.
  • Her research group has been studying mosquito-virus interactions and the use of Wolbachia for biocontrol against mosquito-borne diseases for the past 20 years.

Elizabeth McGraw is a professor and Huck Scholar in entomology. McGraw’s research examines how genetic diversity in a virus like dengue, and in its mosquito host, affects how the virus is transmitted. She also studies the relationship between mosquitoes and their endosymbiotic bacteria, Wolbachia. Her lab is investigating how the bacteria prevents harmful pathogens from replicating inside the mosquito — a trait that is the cornerstone of an international effort to develop Wolbachia-based biocontrol against mosquito-borne diseases.

“The droplets that carry viruses do not stay suspended in humid air as long, and the warmer temperatures lead to more rapid virus degradation,” says Elizabeth McGraw, director of the Center for Infectious Disease Dynamics at Pennsylvania State University.

"Coronaviruses tend to be associated with winter because of how they're spread," explains Elizabeth McGraw, who directs the Center for Infectious Disease Dynamics at Pennsylvania State University.
