Dr. Hal Halvorson (he/him) - Assistant Professor
Hal earned a B.A. in Biology and Chemistry at St. Olaf College in 2011 and his Ph.D. in Biology at the University of Arkansas with Dr. Michelle Evans-White in 2016. He spent 3 years as a postdoctoral researcher with Dr. Kevin Kuehn at the University of Southern Mississippi before coming to UCA in Fall 2019. In his free time, Hal loves to game, listen to contemporary rock music, and explore outside.
Dr. Felicia Osburn (she/her) - Postdoctoral Associate
Felicia earned her Ph.D. in Biology in 2021 from Baylor University in Dr. Thad Scott's laboratory. She has expertise in harmful algal bloom ecology, especially relationships between water quality and cyanotoxin production. Felicia is continuing this research on our Brewer Lake monitoring program as well as teaching courses like Freshwater Ecology and Ecology at UCA as part of the STOICH EPSCoR project.
Molly Wozniak (she/her) - M.S. student
Molly joins us from Lake Superior State University, where she earned a B.S. in Fisheries Wildlife Management in 2020. She conducted undergraduate research on Didymo blooms in oligotrophic streams. She will be working on the field monitoring project in Arkansas Gulf Coastal Plains streams, in collaboration with the Adams Lab at UCA and the Arkansas Division of Environmental Quality!
Anthony Pignatelli (he/him) - M.S. student
Anthony joined the lab in June 2021 from his undergraduate experience in Biology at Kent State University. At Kent, he studied cotton strip decomposition in urban streams of Atlanta. At UCA, he will be working on the NSF EPSCoR STOICH project, with plans to bridge his interests in GIS and ecological stoichiometry to study urban streams of central Arkansas (and beyond!?)
Lydia Bradshaw (sher/her) - M.S. student
Lydia joined the lab in August 2021 after finishing her Environmental Science (Biology track) degree at UCA. She is studying nutrient dynamics in Brewer Lake, the drinking water reservoir for Conway. Lydia has particular interests in external nutrient inputs into the lake and using GIS/remote sensing to analyze watershed effects on water quality.

Ethan Nettleton - M.S Student @ Southern Miss
Ethan is continuing his undergraduate research project as his M.S. Thesis in Kevin Kuehn's lab at Southern Miss. His project investigates the effects of light on wood decomposition in lake littoral settings. Ethan hopes to attend medical school after he finishes his degree.
Saysha Sebren - Ph.D. Student @ Southern Miss
Saysha began her Ph.D. in 2019 in Dr. Kevin Kuehn's lab at Southern Miss. Based on both past and future experiments, her project will use modern bioinformatics and 'omics' tools to study the interplay between microbial community dynamics and leaf decomposition under contrasting light regimes.
