Dave’s great interest in water resources grew from his love of paddle-sports as a teenager. Designing and building canoes and kayaks and working as a buyer for a specialty canoe and kayak retailer taught him to be self directed and learn independently. As an undergraduate and masters student at the UW - Madison, he gained valuable experience as a teaching assistant, research assistant, and as a project manager for multiple national champion student competition teams in both the ASCE Concrete Canoe competition and the Metcalf and Eddy student wastewater treatment design competition. He is currently applying his background and training in management, environmental modeling, geospatial information science, and environmental data analysis at the USGS Water Mission Area. Outside of work, Dave is an avid cyclist. He competes in both road and cyclocross disciplines and enjoys exploring new places by bike every chance he gets.
