Dave was raised in North Dakota. He completed his B.S. in Wildlife Biology at Utah State University (USU) in 2000. From 2002 to 2010 he completed an M.S., Ph.D., and postdoc at USU working on sage-grouse research and conservation. He worked at the Small Game Specialist for the State of Kansas from 2010 to 2013, and then return to USU as an Extension Associate. In 2016, Dave accepted an assistant professor position as the Rangeland Wildlife Habitat Extension Specialist.
