Jeffrey is an Extension Associate and PhD candidate. He works alongside Dr. Bill Hunt as a member of the Stormwater Engineering Group where he provides extension, research, project management, and engineering design for stormwater projects. While the primary focus of Jeffrey’s research is on bioretention, specifically, impacts of aging, maintenance, and design modifications, he has experience in research and design for a wide range of projects including rainwater harvesting, wetland design improvements, and nutrient crediting for stream restorations. Jeffrey holds both undergraduate and master’s degrees from NC State University and expects to complete his PhD this fall. In his free time, Jeffrey loves to travel the world with his wife, Traci, and hang out with their two dogs, Dash and Coco.
