Seeking grad students, Fall 2021

Graduate Student Positions in Aquatic/Fisheries Ecology

Research opportunities:  Dr. Stuart Ludsin ( has openings available for up to three M.S. and Ph.D. students to conduct basic and applied research in aquatic ecology. Research topics include: 1) the ecology of Lake Erie yellow perch (e.g., Are invasive species affecting yellow perch foraging, movement, and vulnerability to anglers?); 2) the ecology of blue catfish and channel catfish in Ohio reservoirs (e.g., Do these species compete for food and habitat?); and 3) the impact of cyanobacteria blooms and hypoxia on Lake Erie’s food webs (e.g., How do these stressors affect habitat use, feeding interactions, energy flow, and (or) cyanotoxin accumulation in the food web?). Students would help design their projects, with each project potentially allowing for the opportunity to do fieldwork (e.g., telemetry), modeling, and experiments.

Location: Successful candidates will join a dynamic, interactive group of students, post-docs, and faculty at The Ohio State University’s Aquatic Ecology Laboratory ( within the Department of Evolution, Ecology, and Organismal Biology (

Qualifications: Successful applicants will be creative, motivated, and capable of working effectively both independently and in collaborative groups. A Bachelor’s degree and (or) M.S. degree in biology, ecology, fisheries, general aquatic sciences, or a related field is required. Strong writing, quantitative, and people-management skills are essential.

Stipend: $2,389/month plus full tuition waiver and health benefits. Graduate Research Assistantship support exists for the first listed two projects, whereas the third project has Graduate Teaching Assistantship support.

Start date: Fall 2021.

How to apply: Application review will begin on Nov. 15, with applications accepted until suitable candidates are found. If interested, please email Dr. Stuart Ludsin ( 1) a letter of interest that briefly describes your educational and research background, as well as  your research interests/goals; 2) a curriculum vitae (or resume); 3) an unofficial copy of your transcript(s); 4) contact information for at least three professional references; and 5) your GRE scores (although they are not mandatory for admission), and if applicable, TOEFL/TSE scores. Please put “Ludsin Graduate Positions” in the subject line.

Congratulations Becca!

Dr. Becca Dillon successfully defended her dissertation today! Her dissertation is titled:

Re-evaluation of north-temperate reservoir food web interactions and their assessment

We are very proud of all of her hard work!

Congrats Undergrads!

Undergrads Brady Rude and Luke Bobay both successfully defended honors theses this week.

  • Brady Rude: Do cyanobacteria blooms increase parasite loads in Lake Erie yellow perch?
  • Luke Bobay: To what degree do preferred prey abundance and temperature influence growth rates of larval yellow perch in Lake Erie?

Great job to both students, and additional congratulations to Brady who is slated to graduate this semester.

Postdoc Manju Manubolu honored

Dr. Manubolu was asked to create a poster for the Fourteenth Annual International Scholar Research Exposition of the Office of International Affairs. This expo showcases the research of current international visiting scholars at The Ohio State University, and only a small group of finalists are asked to create posters for display.  Dr. Manubolu’s poster will be on display in Bricker Hall in November and December. We are proud to have such a great researcher at the AEL!

Stu on the Lake Guardian

Dr. Ludsin joined the Great Lakes Sea Grant Network aboard the Lake Guardian on a Lake Erie cruise for the Cooperative Science and Monitoring Initiative (CSMI) the last week in September.  The cruise was collecting data in central Lake Erie’s hypoxic zone to investigate the impact of hypoxia on the food web.

Like two ships passing in the night, the Lake Guardian met with the Canadian Department of Fisheries and Oceans vessel Cisco to exchange samples and information while on the cruise.

And the beauty of our Great Lake was certainly on display with wonderful sunsets and gorgeous weather.

Dr. Ludsin elected faculty chair of Arts and Sciences Senate

Dr. Ludsin was recently elected faculty chair of the College of Arts and Sciences Faculty Senate. In this role he will preside at meetings of the ASC Faculty Senate and the ASC Senate Steering Committee, the bodies that guide and formulate policy for faculty of the College of Arts and Sciences.  Congratulations to Dr. Ludsin on this appointment!

Stu at ESA 2019

Dr. Ludsin along with post-doc Mike Fraker attended and presented at the Ecological Society of America Meeting in Louisville, KY.

  • Stu’s talk: Modeling physical, chemical, and biological responses to agricultural conservation in a changing climate: Insights from Lake Erie
  • Mike’s talk: Stress hormone-mediated antipredator morphology improves escape performance in wood frog tadpoles
