My research seeks to identify the mechanisms that regulate the structure, function, and dynamics of freshwater and marine ecosystems with a particular emphasis on understanding the impacts of human-driven change on aquatic food webs and the fish populations and communities that they support.

While conducting this research, I have had the honor and pleasure of acting as steward of a decades old Fish Management in Ohio Partnership between the Aquatic Ecology Laboratory (AEL) and Ohio Division of Wildlife (DOW), which was established in the 1980s by my former Ph.D. advisor, Roy Stein. In my current role as director of this partnership, I work with AEL colleagues, DOW biologists, and other university researchers to address fisheries ecology and conservation problems in Lake Erie and Ohio’s inland lakes and reservoirs.

Through this partnership, as well as research collaborations with other Great Lakes and coastal management and regulatory agencies, I use my passion for conducting ecological research and understanding how our natural world operates to benefit the management of our vital ecosystems, including the valued fish populations and the fisheries that they support.


I am currently seeking graduate students to begin in Fall 2022. Please check out the postings on the Aquatic Ecology Lab opportunities page or find a copy of the posting here [pdf].

We have recently announced a Fisheries Science Training Workshop for undergraduates. Application information can be found on the workshop website; applications are due January 17, 2022.


Outreach is a guiding principle of my work since it paves the way for stewardship in the broader community. Science is not complete until we effectively share our findings, so we work hard to share ours with all parts of our community.

Check out that many ways that the Ludsin Lab seeks to share our research with the broader community on the Aquatic Ecology Lab outreach page.
