PhD position in Arthropod Biodiversity & Evolution University of Arkansas, Fayetteville, Arkansas, USA The Forest Ecology & Health Lab at the University of Arkansas is seeking a student interested in pursuing a PhD studying arthropod biodiversity, evolution, and forest ecosystem function. The focal project will be to sample arthropods from high-elevation sites in the Ouachita Mountains of Arkansas and Oklahoma, employ high-throughput DNA barcoding methods to uncover biodiversity patterns, and relate those patterns to environmental variables and ecosystem function. Prospective applicants should have research interests in entomology, ecology, and evolutionary biology, and should have strong field, lab, and analytical skills. Applicants with previous experience using molecular techniques (e.g., PCR, NGS library preparation, metabarcoding, etc.) and bioinformatics are preferred. Experience with GIS and/or R is also desirable. Financial support will be provided through a combination of teaching and research assistantships. Assistantships come with a full tuition (not fees) waiver and 67% of the student health insurance paid for by the university. The selected applicant would need to be admitted to a PhD program at the University of Arkansas for the Spring 2026 semester, which begins January 12, 2026. Students admitted to a PhD program may also be eligible for a U of A Doctoral Fellowship that adds to their assistantship stipend for 4 years. More information about these fellowships can be found at: https://graduate-students.uark.edu/cost-and-funding/index.php. Note that applications for these fellowships require the GRE General Test even if it is not required for admission to a graduate program. Applicants who would be competitive for a doctoral fellowship will be viewed favorably. Continued support will be contingent on satisfactory performance and progress. Research in the Forest Ecology & Health Lab uses field experiments and naturally occurring environmental gradients to examine how biogeochemistry and nutrients impact community structure and trophic interactions among soil arthropods and ant species primarily in forest ecosystems. This project is in collaboration with Dr. Donald Shepard in the University of Arkansas, Department of Biological Sciences, and Dr. Ashley Dowling in the University of Arkansas, Department of Entomology and Plant Pathology. More information about their research and labs can be found at: https://shepardlab.wixsite.com/home and https://adowling.hosted.uark.edu/index.html. Information about the PhD in Entomology program and its requirements is provided here: https://enpl.uark.edu/programs/phd-program.php. Depending on their interests and goals, the selected applicant may have the option to apply through the PhD in Biology program: https://biology.uark.edu/academics/graduate/index.php. To apply, send an email to Dr. Natalie Clay (nclay@uark.edu) that includes as attachments: 1) a cover letter expressing your interest and highlighting your qualifications for the position as well as your future career goals, 2) your curriculum vitae, 3) an unofficial copy of your college transcripts, and 4) names and contact information for three professional references. To receive full consideration, submit your application by August 1, 2025; however, applications will be considered until the position is filled. Note: the selected applicant will still need to apply to and be accepted into a PhD program at the University of Arkansas. The application deadline for Spring 2026 admission is September 1 for Entomology and October 1 for Biology. Please email Dr. Clay (nclay@uark.edu) with any questions or concerns about the project/position. Natalie A.
