Gary Thiede

Gary Thiede on the Utah State University campus.


  • MS Utah State University 1997
  • BS University of Wisconsin-Madison 1990


After receiving his BS at UW-Madison and gaining valuable experience at the Center for Limnology, Gary was a research technician at the Aquatic Ecology Lab at The Ohio State University for two years. He then completed his MS thesis research with Dave Beauchamp (when Dave was still at USU) working with lake trout food-web dynamics in Lake Tahoe. He then worked a few years as a research associate in Todd Crowl’s ecology lab at USU before joining the Peace Corps, serving in Zambia, 1997 - 1999. From 2000 – 2001, Gary worked with Oregon Department of Fish and Wildlife in Portland, and then on Lake Billy Chinook. In 2001, he joined Phaedra Budy at the UT USGS Coop Unit at USU, and has been a research associate, lab manager, and fisheries biologist in her lab ever since. Gary has enjoyed work and research trips to other countries including Zambia, Spain, Pakistan, and New Zealand, and hopes to continue research in interesting locations worldwide.

Research Interests

Gary is generally interested in aquatic ecology in lakes and streams. His specific interests include predator-prey dynamics, food-web dynamics, bioenergetics, fisheries management, sampling techniques, and native fish conservation.
