Research Interests

  • Low density populations
  • Extinction
  • Invasive species
  • Coexistence
  • Allee Effects

Research Projects

A portion of my work is developing species distribution models for aquatic invasive species in the Great Lakes, including the use of machine learning algorithms and presence-only data for model development. I am using network models to better understand spatial spread of disease, focusing on white-nose syndrome in bats. I am part of a long-term project on zooplankton population recovery following fish removal in Sierra Nevada lakes. Several other projects are focused on understanding postive density dependence (Allee effects) in small populations.
