Hello Colleagues,
In addition to our advertisement for Lake Ecology Research Technicians, we are looking for a PhD student to join our research team at Colorado State University. Please find the position description below:
PhD student position: Food web ecology and management of nonnative Mysis shrimp in Grand Lake, Colorado
Location: Dept. of Fish, Wildlife, & Conservation Biology, Colorado State University, Fort Collins, CO
Description: The Department of Fish, Wildlife, and Conservation Biology at Colorado State University invites applications for a funded PhD student position to study ecology and management of nonnative Mysis shrimp in Grand Lake, Colorado. The successful applicant will be based in the laboratories of Dr. Zoe Almeida and Dr. Dan Preston. Nonnative species can restructure food webs, and Mysis have exemplified such consequences following their introduction from their native Great Lakes region to lakes throughout the Western US. In Grand Lake, where a trans-basin water project has contributed to reduced water clarity, there is strong interest in exploring whether reducing Mysis may restore native zooplankton populations and improve water clarity. The successful candidate will design and conduct research to assess how Mysis affect water clarity through food web interactions in experimental settings, especially using laboratory mesocosms. Research may also include leveraging long-term data on water quality and fish populations, in-lake mesocosm experiments, gut content and stable isotope analyses, bioenergetic modeling, and evaluating the ecological roles of Mysis at broader spatial scales using data synthesis. The successful candidate will collaborate with partners and stakeholders at CSU, Colorado Parks and Wildlife, Northern Water, the Three Lakes Watershed Association, and the Bureau of Reclamation.
Candidates must have:
-
An undergraduate degree in limnology, ecology, biology, or equivalent Demonstrated excellence in science communication (scientific writing, presentations) and quantitative skills Ability to communicate clearly and work collaboratively with a research team
Preferred qualifications include:
-
A Masters degree in a related field and demonstrated ability to publish research Experience with experimental design, limnology, fish ecology, and food web analyses (e.g., gut content, stable isotope, and metabarcoding analyses) Experience working with multiple stakeholders Familiarity with common programs used for data analyses (e.g., R software)
Position Start Date: Preferred start date is summer of 2026, which would provide the opportunity for field work before enrolling as a graduate student in Fall of 2026. A later start date is negotiable, but the ideal candidate would formally enroll during the ’26/’27 academic year.
Funding: The position is conditionally funded for 4 years through support from the Bureau of Reclamation and teaching assistantships. Funding includes stipend, health insurance, and tuition.
Application: Please submit a letter of interest (1 page), a CV, and contact information for three references as one PDF file to: Dr. Zoe Almeida (
l.zoe.almeida@colostate.edu)
and Dr. Dan Preston (
Dan.Preston@colostate.edu) (please use subject “PhD application: Mysis experiments”). Finalists will be invited to apply through the Colorado State University Graduate School.
Closing Date: Review begins immediately with interviews on a rolling basis and will continue until the position is filled.
