What if the turtle shell, one of the most famous inventions in vertebrate evolution, was never a solo act? What if amphibian communities carry microbial histories that help explain why some populations collapse and others persist? A new funded M.S. position at Eastern New Mexico University is built around those questions, and it comes with tropical fieldwork, metagenomic sequencing, and close mentorship from a lab that is just getting started.
The Microbial Ecology and Macroevolution Group in the Department of Biology at Eastern New Mexico University (ENMU) in Portales, New Mexico, is recruiting one master’s student for Spring 2027. The student will study how microbes shape the evolution of their animal hosts, working with turtles and amphibians and combining summer field seasons in Panama, and potentially the Ecuadorian Amazon, with shotgun and long-read metagenomics. Full consideration goes to applications received by 2 November 2026.
This is not a generic teaching assistantship with a side project. It is a research-centered graduate assistantship with a defined field program, computational training, and the unusual chance to be the first graduate student in the group.

Why This Funded MS Graduate Assistantship in Microbial Ecology 2027 Stands Out
Most master’s ads promise “flexibility.” This one is more specific. The lab studies how microbes and their metazoan hosts shape biodiversity across levels of biological organization, with special attention to evolutionary novelties, innovations, and constraints on adaptation. Turtles and amphibians are the main study systems.
That framing matters. The project is not only “sequence some microbiomes and compare sites.” It asks whether host-associated microbes help explain major evolutionary outcomes, including the origin of the turtle shell, how microbiomes are transmitted, how they change along environmental gradients, and how they mediate developmental trajectories. Thesis questions are developed with the principal investigator, Joseph Madison, inside that research program. They are otherwise flexible enough to match a student’s strengths.
The student will also join a rare mentoring setup. Because this will be the first graduate student in the group, the working relationship with the PI will be close. Madison has previously mentored undergraduates, graduate students, and postdoctoral researchers and is a Research Associate at the Smithsonian Tropical Research Institute (STRI). The Department of Biology at ENMU already has other graduate students, so the new student will not be isolated, but they will have an unusually direct role in shaping a young lab.

The Science: How Microbes May Shape Host Evolution
The group’s working name on the lab site is the Microbe-host Ecology and Macroevolution (MEME) Group. Its core claim is simple and ambitious: microbial processes leave signatures on biodiversity and health that are visible at organism, population, and clade scales.
Possible thesis directions listed in the official advertisement include:
- How host-associated microbiomes vary along environmental gradients
- How those communities are transmitted across generations or among individuals
- How microbes mediate developmental trajectories, including gene-expression patterns tied to turtle shell formation
- How patterns differ across levels of selection
On the turtle side, the lab is interested in the microbial role in the origin of the shell, using living species across North and South America. Questions include whether microbiomes differ among conspecifics at different sites, whether they are vertically transmitted, and whether they help explain evolutionary-developmental features such as carapacial ridge gene expression and the rib-scapula inversion that produced the shell. On the amphibian side, the work can include host-associated microbes from living animals and, in the broader lab program, from fluid-preserved museum specimens, including questions about diversity, function, land-use change, and disease-related declines.
Methods are mixed by design. The student should expect field collection, laboratory processing, shotgun and long-read metagenomics, multi-omics approaches where they fit, and bioinformatic analysis on high-performance computing resources. Experience with bioinformatics and statistics is desirable, not mandatory on day one, but applicants who already enjoy computational work will have a head start.
For a conceptual overview of the research program, see Madison’s essay Microbe-metazoan macroevolution: new directions for an old research program.
Fieldwork in Panama, and Possibly the Ecuadorian Amazon
Coursework happens in Portales during the academic year. The summers are for the field.
Fieldwork will take place in Panama with the Smithsonian Tropical Research Institute, where the PI is a Research Associate. STRI is the Smithsonian bureau based outside the United States and is one of the world’s main centers for tropical biology. A second possible site is the Tiputini Biodiversity Station in the Ecuadorian Amazon, inside the Yasuní Biosphere Reserve, working with local collaborators. Regional fieldwork in the Chihuahuan Desert around eastern New Mexico is also possible.
Two full summer field seasons are expected. The degree is planned for about two years, which means applicants must be ready to start in January 2027 and stay available for consecutive summer campaigns. Some sites are remote, with limited access to medical care. The PI will plan field safety and emergency logistics with the student, but this is physically demanding work. Applicants should be comfortable in heat, humidity, long days, and conditions that do not resemble a campus laboratory.
Working Spanish is preferred because the international field sites are in Latin America. Tropical field experience, ideally from an undergraduate program, is also preferred. Neither is an absolute barrier if the rest of the file is strong, but both will stand out.
Funding, Location, and Daily Life
Funding is a graduate assistantship plus summer support:
- About $11,000 stipend per 9-month academic year
- Tuition charged at the in-state rate
- Summer stipend of up to $5,000 for each field season
- Support for field costs
- Combined package of about $16,000 per year, plus field expenses
Students are encouraged to apply for external fellowships if they want additional support. Graduate assistantships are also processed separately through ENMU’s employment site after the lab match.
ENMU is a federally designated Hispanic-Serving Institution in Portales, a small town on the High Plains of eastern New Mexico. The cost of living is low compared with most U.S. university towns. That matters on a master’s stipend. The official M.S. in Biology page describes the program as one of the more affordable biology master’s options in the Southwest and offers both thesis and non-thesis paths; this assistantship is clearly intended as a thesis project. Learn more on the ENMU Master of Science in Biology page.
Hours are listed as 30 to 40 per week on the job board posting. In practice, graduate research does not clock out neatly, especially during field seasons.

How to Apply for Funded MS Graduate Assistantship At Eastern New Mexico University
Do not start with a generic graduate-school form if you want this specific assistantship. The lab wants a targeted packet first.
Email the following to joseph.madison@enmu.edu with the subject line “ENMU MS Position”:
- A statement describing your interest in the lab, this project, and your career goals
- Your CV
- Unofficial transcripts
- Contact information for two references
Applications are reviewed as they arrive. Full consideration is given to packets received by 2 November 2026. After a successful match, the student applies for the graduate assistantship through ENMU’s employment site and completes Graduate School admission.
Read the full advertisement before writing: https://kvasir7.github.io/ENMU_MS_ad_2026.pdf. Then look at the lab site, https://kvasir7.github.io/, so the statement of interest sounds like it was written for this group and not copied from another microbiome lab.
Questions are welcome at the same address. Use the specified subject line so the message is not lost.
How to Write a Statement That Gets Read
A strong statement for this funded MS graduate assistantship in microbial ecology 2027 should do four things quickly.
First, show that you understand the intellectual bet. The lab is not only surveying microbes on turtles and frogs. It is asking whether microbes help produce, constrain, or transmit evolutionary outcomes. Mention a concrete question you would like to pursue, even if it will change.
Second, prove that you can finish hard field seasons. Remote tropical work rewards people who have already carried a project through bad weather, broken plans, and incomplete data. Describe what you actually did, not only where you traveled.
Third, be honest about skills. If you have used R, QIIME 2, command-line tools, or high-performance computing, say so. If you have not, say what you are ready to learn and how you have learned technical skills before.
Fourth, explain why ENMU and this PI. Being the first graduate student is a feature and a risk. It means more attention and more responsibility. If that appeals to you, say why.
Keep the statement specific. Named field sites, named methods, and a short account of an independent project are more persuasive than broad enthusiasm for “biodiversity and conservation.”
Timeline and Practical Checklist
- Now through early October 2026: Read the PDF ad and lab site. Draft the statement. Ask two references if they will speak to research potential and field reliability.
- By 2 November 2026: Submit the email packet for full consideration.
- November–December 2026: Interviews, follow-up questions, and Graduate School materials if invited to proceed.
- 11 January 2027: Planned start in Portales.
- Summer 2027 and Summer 2028: Expected field seasons in Panama and possibly Ecuador.
Also prepare a passport with enough validity for international travel, confirm that you can hold a driver’s license, and think through vaccinations and medical planning for remote fieldwork. Those details are not the first thing the PI will score, but they determine whether a January start is realistic.

Final Word
Funded master’s positions that combine a clear evolutionary question, tropical fieldwork at STRI, and training in modern metagenomics are uncommon. Positions that also make you the first graduate student in the group are rarer still. The stipend is modest by R1 standards, but in-state tuition, summer field pay, covered field costs, and a low cost of living in Portales change the arithmetic. The work itself is the main draw: turtles, amphibians, microbes, Panama, and the chance to test whether host-associated communities help explain how animal body plans and communities evolve.
If that combination matches your training and your tolerance for remote fieldwork, contact Joseph Madison at joseph.madison@enmu.edu with the subject line “ENMU MS Position,” and send a complete packet before 2 November 2026.
