Dave Smith graduated from Colorado State (MS in Fish and Wildlife Biology) and University of Georgia (MS in Statistics and PhD in Forest Resources). Currently, he is a biological statistician at the USGS Leetown Science Center where he focuses on applied quantitative ecology in support of natural resource management and environmental decision making.
His research activities mostly focus on the following topics:
- Adaptive sampling of rare and clustered populations
- Conservation and science of horseshoe crabs in North America and Asia
- Conservation of freshwater mussels
- Application of structured decision making and adaptive management to natural resource management
