Curriculum Vitae

  • Profile

    Dr. Priscilla Erickson is an assistant professor of biology at the University of Richmond. She received a B.A. in molecular biology from Kenyon College and a Ph.D. in molecular and cell biology from the University of California, Berkeley. She conducted postdoctoral research with Dr. Alan Bergland at the University of Virginia, studying rapid evolution in fruit flies. Her current research focuses on a species of fruit fly that was accidentally introduced to the United States. This tropical species is highly successful in Virginia orchards in the summer but cannot survive sub-freezing winters. The Erickson lab is interested in learning how this species may be adapting to our seasonal environment here in Virginia as a model of how invasive species evolve and succeed in new environments. The lab uses a combination of fieldwork, lab experiments, and genome sequencing to study rapid evolution in these flies. Learn more about the Erickson lab at ericksonlab.net. Dr. Erickson teaches courses in molecular biology, evolution and ecology, genetics and genomics, and bioinformatics.
