My research focuses on understanding and preventing the introduction, spread, and impact of non-native species in aquatic ecosystems. My work ranges from genetic approaches for reconstructing invasion histories (determining sources of invaders and tracking their spread, primarily in coastal systems), development of and implementation of molecular tools for early detection, monitoring, and control of invasive populations, and application of geospatial analyses for understanding the drivers of aquatic invasions and their ecological and socio-economic impacts, particularly their role in the decline of native aquatic biodiversity.

Coordinated development of exposure research in the Sustainable and Healthy Communities Research Program.
