Biography
Dr. Irwin received graduate degrees from Auburn University and Cornell University and was a post-doctoral researcher at the Quantitative Fisheries Center at Michigan State University prior to joining the Georgia Cooperative Research Unit in 2012. He currently is an Assistant Unit Leader and an Adjunct Associate Professor of the Warnell School of Forestry and Natural Resources at the University of Georgia. Brian’s research interests are in areas of ecological change, fish population dynamics, and decision making linked to long-term monitoring and management of natural resources. He has worked on a number of natural-resource management problems where he has applied a “Structured Decision Making” process to evaluate alternatives and consider the role of uncertainty. Projects have also used quantitative models to explore how populations respond to anthropogenic and natural influences. He enjoys collaborative projects, which have included federal, state, and university cooperators. At UGA, he regularly interacts with graduate students and teaches courses which introduce concepts and analyses relevant to modeling data, conservation decision making, and sustainable use of exploited natural resources.
