Field(s) of Research:
  • Aquatic Invasive Species
  • Limnology / Freshwater ecology

Research Description:
My current research interests include addressing a wide variety of questions pertaining to aquatic invasions in the Great Lakes and the Arctic. My main research interests include planktonic invaders, vectors and pathways of introduction, risk assessment and developing and evaluating strategies to prevent introductions. I am also interested in exploring the relationship between population density and invasion success. My lab has an array of automated tools, including a FlowCAM, high resolution Laser Optical Plankton Counter with Acrobat towbody, and epi-fluorescent microscope system to facilitate our research. Our lab is very active and productive; most of the research we do is based on MSc and PhD research projects in collaboration with various people in DFO, universities, and other research institutes. Potential graduate students or post-docs with an interest in applied invasion biology are welcome to contact me to explore opportunities to work/study in my lab.
