Research Interests & Approach:

I have a general interest in fisheries biology with emphasis on research questions related to population and community ecology. My research focuses on streams, lakes, and wetlands. In addition to fishes, benthic macroinvertebrates are often a focal study species. I enjoy both empirical and theoretical approaches to research, and I strive to include mathematical modeling in my research.  I have a strong interest in experimental design and statistical analyses, which are critical for planning and executing empirical research.

My current research includes studies that examine the distribution and ecological impacts of the invasive round goby in the Great Lakes ecosystem, assess the long-term dynamics of fish populations in a local lake impacted by current and past anthropogenic activities, evaluate sampling bias of fishes, investigate the role of fish predation in structuring stream food webs, and identify recruitment bottlenecks in fish populations.  Undergraduate and graduate students are an important component of my research program, and I pride myself in mentoring students.
