Join the lab!

Prospective graduate students

Graduate (MS or PhD) Students- I will be accepting 1-2 graduate students to begin Fall 2021. Graduate students should expect to conduct research along the major themes of the lab (see Research and Publications), although there is flexibility for grad students to design projects that best suit their interests. Potential study topics may include evolution of plant defense across climate gradients, influence of neighboring plants on herbivory rates and population dynamics, variation in the effectiveness of biocontrol insects on invasive plants, plant-soil-insect interactions, among others.

Students can pursue an MS or PhD in Entomology through the Department of Entomology and Nematology or through the Interdisciplinary Ecology program in the School of Natural Resources and the Environment. Funding may be available through competitive departmental or university fellowships. Strong applicants will need to apply to the University of Florida by 15 January 2021. Applicants for an MS degree should hold a BS in biology, ecology, entomology, or closely related field. Applicants for a PhD degree should have a MS or equivalent experience. I encourage interested graduate students to check out fellowship opportunities that you may be eligible for (e.g., NSF GRFP, USDA-NIFA, and other opportunities on the UF-EntoNem page).

Prior to applying, please send an inquiry email and CV to Dr. Phil Hahn at For best consideration, please inquire by November, 2020. In the body of the email or a separate attachment, please describe your research interests and experience, career goals, and three potential study topics you may be interested in pursuing.

Gainesville is a great place to live, with affordable cost of living, ample outdoor recreational opportunities, and more. UF has a very strong ecology program across many departments and recently ranked as one of the top universities in the world for ecology.

Postdoctoral researchers and technicians

I am always excited to chat with potential postdoctoral research associates about developing research ideas and fellowship proposals. See here for a list of potential postdoc fellowships. See below for current (funded) postdoc and tech opportunities:

NEON postdoctoral fellowship: NEON recently opened a call for postdoctoral fellow applications (due May 8, 2020). UF has one NEON site near campus (Ordway-Swisher) and two other sites nearby. If you have ideas for projects that use NEON data related to plant ecology, insect ecology, functional traits, or species interactions, please get in touch if you are interested in collaborating!

Postdoctoral Research Associate– We are accepting applications for a new postdoctoral position. We seek a motivated and enthusiastic scientist who will join a NSF-funded collaborative project between Drs. Phil Hahn (University of Florida) and John Maron (University of Montana). The project aims to test hypotheses regarding the evolution of plant defense.  Specifically, we seek to understand how resource availability shapes evolutionarily fixed and plastic growth~defense tradeoffs both within and among plant species. Field work takes place in Wisconsin and western Montana. The successful candidate will take a strong leadership role on the project as well as actively participating in activities within the Hahn lab. Specific duties include coordinating research activities in the field, lab, and greenhouse, supervising research technicians, collecting/analyzing data, writing manuscripts, and presenting talks at scientific meetings. Although the position will be based at the University of Florida, the candidate will work at field sites in Wisconsin and/or Montana during the field season (May-Sept.). Expertise in plant, insect, and chemical ecology (along with a strong conceptual foundation in ecology and evolution) is preferred although expertise in a subset of these areas may suffice.

This is a one-year position, but with the strong possibility of it extending for an additional 1.5 years (2.5 years total). Minimum salary is $47,476, with a start date between January-March 2020 (although there is some flexibility for a start date later in spring 2020). To apply, please submit a single pdf document containing a cover letter/statement of interest (1-2 pages), CV, list of three references (email and phone), and two recent publications to Dr. Phil Hahn ( In the statement of interest, please describe your past research accomplishments, future directions, and how your research interests align with the goals of the project. For inquires or to discuss the position prior to applying, please contact Phil Hahn via email. For further information on Phil Hahn’s lab at UF see: The position will remain open until filled, but please apply or inquire by 31 Oct. 2019 for best consideration.

Lead Technician: We will soon be recruiting for a lead technician position located in Gainesville with travel to Wisconsin and/or Montana during the field season.

Undergraduate research opportunities

Undergraduate students play a critical role in the lab. Highly motivated students with interests in insect ecology and plant-herbivore interactions may enter the lab through various avenues: 1) research volunteers, 2) student researcher interns (for credits through the Dept. Ento/Nem), or 3) as paid research technicians. Please take a look at our Research page and list of publications for more info about our research projects. Contact Dr. Phil Hahn to inquire about working in the lab.
