Area of Interest

My research focuses on examining how disease outbreaks, community structure, and stochasticity influence population dynamics by combining field-based experimental and theoretical modeling approaches. I'm particularly interested in:

  • Virus transmission and insect outbreaks
  • Variability in disease transmission
  • Disturbance and riparian community structure
  • Population viability and rare species management

If you're interested in joining my research group, please email me. I'm seeking both students and post-docs to work on projects involving either population or community ecology. In particular, I take a quantitative approach to ecological questions and would require that my students have some interest or training in mathematical ecology/modeling. While students may work on projects closely affiliated with my research, I encourage them to seek out their own research identity.
