Dr. Kauffman grew up in rural southern Oregon, the son of a horse logger and an elementary schoolteacher. He received his B.S. in Biology from the University of Oregon in 1992 and his Ph.D. in Environmental Studies from the University of California, Santa Cruz in 2003. Kauffman is a wildlife biologist with a broad organismal background. He has worked across a number of ecological disciplines, blending traditional fieldwork with ecological models to address conservation and management issues.

Teaching Interest

I teach graduate courses in quantitative analysis of spatial wildlife data, community ecology of wildlife, and migration ecology.

Research Interest

Matt leads a scientific team at the University of Wyoming that has broken new ground exploring the long-distance migrations of Wyoming's large ungulates and communicating their importance to the public. His research seeks to understand how and why ungulates migrate, by evaluating the role of forage, movement, fat dynamics, reproduction and survival. Increasingly, he has sought to understand how the persistence of ungulate migration is threatened by landscape change. In 2012, Matt co-founded (and now directs) the Wyoming Migration Initiative (, whose mission is to advance the understanding, appreciation, and conservation of Wyoming's migratory ungulates. Since 2006, Matt has worked as a USGS researcher with the Wyoming Cooperative Fish and Wildlife Research Unit and as faculty in the Department of Zoology and Physiology at the University of Wyoming; in 2010 he assumed leadership of the Wyoming Coop Unit.
