I am interested in the ecological, economic and social causes and consequences of species invasions. One main focus of my research is the development of risk assessment tools for predicting the identity of species that are likely to become invasive if they are spread beyond their native range. I am presently working as part of a large project to produce such risk assessment tools for all aquatic taxa currently being introduced to the Laurentian Great Lakes Basin through trade. Additionally, I am working with economist collaborators to calculate the economic benefits from removing these invasive species from trade. Another ongoing project is investigating the implications of invasive species for international environmental justice.
I spend a lot of time meeting and working with policy-makers at the city, state, regional and national levels to ensure that my research addresses important questions, and that my results are communicated to those who can use them.
