Research Scientist

I am a bio-physical limnologist and ecosystem scientist specializing in lower-trophic food web dynamics in the Great Lakes.

Current research and/or projects

My research is focused on the role of phytoplankton and zooplankton to support of healthy ecosystems and sustainable fisheries within the Great Lakes. I employ a combination of empirical collection and modeling approaches, and I use modern sensor technology to collect information on plankton composition, distribution and size. Projects include impairments in phytoplankton and zooplankton within Areas of Concern, food web impacts of invasive species such as Dreissenid mussels and predatory cladocera such as Bythotrephes and Cercopagis, impact of Harmful Algal Blooms and hypoxia on planktonic food webs, and the binational Cooperative Science and Monitoring Initiative. I am particularly interested in feeding interactions and growth of zooplankton. Much of our work is in collaboration with other Canadian and US federal and provincial/state agencies.
