Joel Bostic, Research Scientist
Photo of Joel BosticJoel earned a Ph.D. in 2021 from the MEES program, and was co-advised by Dr. Keith Eshleman. Joel’s dissertation investigated the effect of land use patterns on the export of nutrients in streams within the Chesapeake Bay watershed. Joel received a B.S. in science education from Western Carolina University and a M.S. in marine science from the University of South Carolina. He is currently a scientist in the lab in the summers and assistant professor at nearby Potomac State College during the academic year. When he’s not doing research or teaching, Joel enjoys hanging out with his wife and sons, biking and trail running in the mountains, and whitewater kayaking.

 

 

 

Sarah Endyke, Ph.D. Studen

Before beginning graduate school, Sarah earned her B.S. in environmental science from the University of Massachusetts, Amherst.

 

 

 

 

 

Nicole Ibrahim, Ph.D. Student

Nicole is using stable isotopes to understand bird migration in western North America and Kazakhstan. She earned a B.S. in wildlife ecology from the University of Wisconsin Madison in 2021.

Jonathan Johnson, Ph.D. Student

Jonathan is using paleoecological tools, including carbon isotope analyses of fossil pollen grains, to investigate factor(s) controlling abrupt shifts in forest tree community composition during the Holocene in the Great Lakes region of North America. He participates in the U.S. Geological Survey’s Pathways Program where he studies forensic palynology and geomorphology. Before beginning graduate school, he served in the U.S. Air Force for 6 years and later completed his B.S. in geology at West Virginia University. During his off time he enjoys spending time with his wife, friends, exercising, and hockey.

Juliet Nagel, Ph.D. Student

Juliet is studying the population dynamics of migratory tree-roosting bats using acoustic and genomic data. She works with Drs. Nelson, Gates, and Gugger. Juliet received a B.S. in Wildlife Ecology and Management from the University of Wisconsin Stevens Point and a M.S. in Zoology from the University of Western Ontario.

 

 

 

 

Grace O’Hara, M.S. Student

Grace earned a B.S. in environmental science from Union College in 2022. She is investigating the effect of “green” stormwater infrastructure on nitrogen cycling in a rapidly urbanizing Chesapeake Bay watershed.  She is co-advised by Dr. Keith Eshleman.

Caitlin earned her M.S. degree in the Wildlife and Fisheries program in 2018 from the Department of Biology at Frostburg State University. She  studying the movements of migratory tree-roosting bats using stable isotope data and geospatial modeling. She has begun her Ph.D. studies in Hannah’s lab in the Department of Biology at the University of Florida.

 

 

 

 

Hannah Vander Zanden, Postdoctoral researcher, 2016-2017

Hannah was affiliated with the lab as a postdoctoral researcher using stable isotope analyses to identify the geographic extent of wildlife fatalities at renewable-energy facilities in California in collaboration with Drs. Nelson and Katzner. She’s currently an assistant professor in the Department of Biology at the University of Florida.

 

 

 

 

 

Vanessa Cunningham, 2014-2016

Vanessa earned her M.S. degree in 2016 through the MEES program and was co-advised by Dr. Andrew Elmore. Vanessa used a combination of remote sensing and isotopic techniques to investigate factors controlling the stability of growing-season canopy greenness in the eastern deciduous forest.

 

 

 

 

Cortney Pylant, 2012-2014

Cortney earned her M.S. degree in the Wildlife and Fisheries program in 2014 from the Department of Biology at Frostburg State University and was co-advised by Dr. Stephen Keller. Her research investigating the impacts of wind-turbine mortality on bat populations using stable isotopes and molecular techniques was awarded an EPA STAR Fellowship.  She’s currently a biologist in a conservation genetics lab at the University of Florida.
