NIMBioS Postdoctoral

NIMBioS has many opportunities for postdoctoral scholarship at the interface between mathematics and biological science through grant-funded projects led by researchers working at NIMBioS. If you are interested in joining our community in such a role, please check out currently available positions. If you are thinking more in the long term and would like to discuss collaborating on a proposal that would include postdoctoral support, please contact us and we will see if we can find a likely partner to discuss preparing future grants together.

Since our first cohort of postdoctoral fellows in 2009, NIMBioS has supported 48 researchers for two-year fellowships. The NIMBioS Postdoctoral Fellowship program is designed to help fellows succeed in future endeavors, whether as a faculty member at a R1 institution or liberal arts college, a position in government, or conducting research in industry. More than 85% of NIMBioS postdoctoral fellows accept faculty positions at the world's top institutions (Top 500, Shanghai Rankings), a far higher success rate than most postdoctoral programs. Through their NIMBioS fellowship, postdocs have produced over 200 journal papers, nearly 200 presentations or posters, and a handful of book chapters.

Meet our Postdocs

Chuck Price

Chuck Price works with Mona Papes and Todd Schroeder of the U.S Forest Service. His research utilizes both drone and terrestrial based lidar to quantify the volume and structure of Mangrove forests along the Florida coast, Puerto Rico, and the U.S. Virgin Islands to better estimate changes in structure and biomass due to disturbances, such as hurricanes.

Kimberlyn Roosa

Kimberlyn Roosa works Nina Fefferman’s lab, where she studies infectious disease epidemiology, looking at how personal or community interventions can impact the overall population disease dynamics and also works with the University of Tennessee One Health Initiative.

Brittany Story

Brittany Story is a second year postdoctoral researcher at University of Tennessee Knoxville as a part of NIMBioS under Vasileios Maroulas. Her current work looks at using topology to understand neural connectivity.

Denis Tverskoi

Denis specializes in mathematical modeling of human behavior, collaborating with DySoC Director Dr. Sergey Gavrilets at UTK. Together, they create models exploring individual decision-making, belief formation, and the evolutionary origins of these behaviors.

Matthew Hasenjager

Matthew Hasenjager's background in studying networks brought him here to work in NIMBioS Director Nina Fefferman’s lab, to use network analysis to understand complex systems of interacting agents.

Jennifer Peters

Jennifer joined NIMBioS last year to work on a joint project with the US Forest Service, using remotely sensed imagery to study forest canopy structures on a large scale. This project dives into the use of remotely sensed data to improve the USFS inventing mission. She is also using the data from this project to investigate forest structure recovery after fires occur.

Wyatt Mackey

Wyatt Mackey works in Vasileios Maroulas’ lab here at the University of Tennessee, working to help artificial intelligence work more like the human brain—and to try to understand the brain in the first place! Wyatt tries to draw ideas from a number of different fields: biology, topology, information theory, and computer science are all things he thinks about on a daily basis.

Narayani Barve

Ecology and Evolutionary Biology

Sam Jantz

As a postdoctoral fellow with the Armsworth, Giam, and Papes labs, Sam focuses on creating land-use change projections for the Appalachians to understand climate and land-use impacts on biodiversity.


Our mission is to foster the growth of transdisciplinary approaches within mathematics and biology
