Dr. Erick Gagne holds a PhD in Ecology and Evolutionary Biology from Tulane University. He recently completed his post-doctoral research in Dr. Sue VandeWoude’s Lab at Colorado state University, his work there used genomic data to determine how landscape characteristics shape disease spread in wildlife. In addition, their research was investigating disease spillover -transmission of a pathogen from a reservoir host population to a novel host- between domestic animals, wildlife, and humans.


Erick's work uses molecular and ecological techniques to better understand population structure of wildlife as well as the origin and epidemiology of infectious disease in wildlife. The goal of this work is to further our understanding of the ecology and evolution of wildlife as well as their pathogens in order to guide remediation and prevention of wildlife disease.
