Academic highlights

  • Research Scientist: University of Nevada Reno, 2009-2012
  • PhD: University of California Davis, 2008
  • MA-Biology: Humboldt State University, 2004
  • BS: Humboldt State University, 2000 

My research focuses on the ecological maintenance and evolution of infectious diseases in wild animals and how this translates into transmission of disease to humans, domestic animals, and wildlife. I use a mixture of microbiology, molecular biology, and population ecology to investigate empirical infectious disease dynamics in wild animal populations.
