Dr. Brian Irwin

Brian Irwin


  • Ph D Cornell University 2006
  • MS Auburn University 2001
  • BS University of Illinois 1998


I am Assistant Unit Leader (Fisheries) at the GA Cooperative Research Unit and a faculty member of the Warnell School of Forestry and Natural Resources at the University of Georgia.

Research Interests

My research interests are in the areas of ecological change, fish population dynamics, and decision making linked to conservation and management of natural resources. Current projects involve using quantitative models to explore how populations respond to anthropogenic and natural influences.

Teaching Interests

My courses introduce concepts and analyses relevant to conservation decision making and sustainable use of exploited natural resources.
