Graduate Student Positions in Aquatic/Fisheries Ecology - Dr. Ludsin

Research opportunities:  Dr. Stuart Ludsin (u.osu.edu/ludsinlab) 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 impact of harmful algal blooms (HABs) on western Lake Erie’s food web (e.g., How do HABs 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 (ael.osu.edu) within the Department of Evolution, Ecology, and Organismal Biology (eeob.osu.edu). 

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 Lake Erie yellow perch project (project 1 above), whereas Graduate Teaching Assistantship support exists for the Lake Erie HABs project (project 2 above).

Start date: Fall 2022.

How to apply: Application review will begin on November 15, 2021, with applications accepted until suitable candidates are found. If interested, please email Dr. Stuart Ludsin (ludsin.1@osu.edu), with the subject line "Ludsin Graduate Positions" and include the following information:

  1. A letter of interest that briefly describes your educational and research background, as well as  your research interests/goals;
  2. Your 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.

Independent Study

The Aquatic Ecology Laboratory (AEL) is interested in energetic, committed undergraduate students who are interested in conducting independent research, for OSU credit, that focuses on ecologically oriented projects in freshwater ecosystems. For all projects, we ask students for, at minimum, a commitment of one year. For more information, please contact Drs. Stuart LudsinElizabeth Marschall, or Jim Hood

Work Study

We are looking for qualified students to fill work-study positions at the AEL. Specific tasks for our Work-Study students include field sampling, in-lab sample processing, and data entry. We strive to ensure that Work-Study students also have opportunities to participate in lab and field research associated with other ongoing projects. AEL graduate students and faculty are committed to educating Work-Study students in the art of scientific research in a cooperative and supportive work environment.
