Barry McKnight once again heads to McCall Hall on the Troy campus, where this month he talks with Dr. Brian Helms of the Department of Biological and Environmental Science. Dr. Helms is passionate about his active, hands-on research about the removal of the Elba Hydroelectric Dam’s effect upon the Pea River populations of indigenous fish and mussels, and he shares that passion (and another exciting project) on the latest Trojans Talk Research Podcast.
