Environmental Science student journeys from Army service to leading Ohio River research

Environmental science major Stephen Balko is combining undergraduate research, fieldwork and conservation planning to help improve understanding of the Ohio River and its ecosystems.

After discovering the Ohio River Way Challenge as a Marshall student, Balko joined the program’s research team in 2025 and returned this year as its leader. Working alongside students and conservation partners, he helped coordinate fish habitat surveys, water quality testing, insect sampling and GIS mapping along hundreds of miles of river.

“I think that was really cool outside of the wildlife stuff, because initially I just came in for working with animals, but now I work more with people and communicating along the river,” Balko said.

A former Army servicemember, Balko has also gained research experience through the Department of Natural Resources & Earth Sciences and has presented his work at professional conferences.
