The round goby, a small but aggressive fish native to the Black and Caspian Seas, has quietly rewritten the rules of North American freshwater ecosystems. First detected in the Great Lakes in 1990 via ballast water, this prolific invader has marched south through the Chicago Area Waterway System, down the Illinois River, and into the Upper Mississippi River Basin. It outcompetes native benthic fishes, preys on eggs and mussels (including species of conservation concern), and thrives in degraded habitats that many native species cannot tolerate. Now researchers face a critical window: map its current distribution, quantify its ecological impacts, and generate data that managers can use before the invasion accelerates further into the vast Mississippi River system.
If you hold a master’s degree in biology, ecology, fisheries, wildlife biology, or a related field and want your doctoral research to deliver real-world management outcomes, Illinois State University’s Andres Lab is recruiting a fully funded PhD student for exactly this challenge. This is not a purely theoretical project. It is a funded research assistantship that combines cutting-edge molecular tools with aquatic fieldwork and direct collaboration with state and federal scientists.

Why This Fully Funded PhD in Freshwater Invasion Ecology Matters
Aquatic invasive species rank among the most urgent threats to freshwater biodiversity and ecosystem services in the United States. The round goby (Neogobius melanostomus) exemplifies the problem. In the Great Lakes it has reached high densities, altered food webs, and even contributed to shifts in recreational fisheries. Its recent establishment in the Illinois Waterway and documented presence near the confluence with the Mississippi River raise the stakes dramatically. Once established in large river systems, control becomes exponentially harder.
The Andres Lab project addresses this gap head-on. The successful PhD student will use environmental DNA (eDNA) to detect the species’ current distribution at scales that traditional sampling often misses, apply diet metabarcoding to reveal what round gobies are actually eating in novel habitats, and employ genomics to understand population structure and invasion pathways. The results will feed directly into management decisions by agencies charged with protecting the Upper Mississippi River Basin. Students who complete this work graduate with a rare combination of field skills, molecular expertise, and policy-relevant experience that is highly valued by academic, government, and non-profit employers.

Requirements for Fully Funded PhD in Freshwater Invasion Ecology at Illinois State University
Ideal Candidate Profile
Competitive applicants will hold an M.S. degree and demonstrate:
- Excellent written and verbal communication skills
- Ability to work both independently and as part of collaborative teams
- Evidence of research productivity appropriate to career stage (publications, presentations, or strong thesis work)
- Strong experience with aquatic fieldwork
- Familiarity with molecular laboratory techniques such as DNA extraction, PCR, qPCR, library preparation, or next-generation sequencing
Prior experience with eDNA, metabarcoding, or invasion ecology is advantageous but not strictly required; the lab provides training in these methods. The most successful candidates will show genuine curiosity about freshwater systems, a commitment to conservation-relevant science, and the resilience needed for both field and lab work.
How the Research Unfolds
Fieldwork will focus on the Illinois and Mississippi River systems as the round goby expands its range. Sampling designs will integrate eDNA surveys with traditional fish sampling to validate detections and estimate occupancy. Diet metabarcoding will illuminate trophic interactions—whether round gobies are preferentially consuming native invertebrates, fish eggs, or mussels—and how those interactions change across environmental gradients. Genomic approaches will help reconstruct invasion history and identify source populations, information that is essential for preventing further secondary spread.
Because the project is designed with management applications in mind, the PhD student will interact regularly with agency partners. This collaboration accelerates the translation of results into monitoring protocols, risk assessments, and potential response strategies. It also builds a professional network that often proves valuable after graduation.
Life and Research at Illinois State University
Illinois State University’s School of Biological Sciences offers a research-active environment with sequences in Behavior, Ecology, Evolution, and Systematics among other areas. The campus in Normal provides a supportive setting for graduate study, with access to laboratory facilities for molecular work and proximity to major river systems for fieldwork. The Andres Lab emphasizes inclusive, collaborative research focused on conserving aquatic biodiversity in the face of anthropogenic change. Lab members gain experience with the full pipeline of modern invasion ecology—from sample collection and laboratory processing to data analysis, manuscript preparation, and scientific communication.
More information about the lab’s broader research themes and the School of Biological Sciences can be found on the official faculty and departmental pages. Prospective students are encouraged to explore these resources before applying.
