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 working on understanding the role of marine aggregates (marine snow) in transmission of aquatic pathogens by modeling bacterial dynamics and species interactions. 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.
