Joe is currently working on his doctorate with Dr. Colden Baxter in collaboration with Dr. Kurt Fausch at Colorado State University. He received his M.S. in Biology at Boise State University. His Master’s project investigated factors influencing the presence of nonnative brook trout. In his current research, Joe combined his interests of nonnative species with community ecology and ecosystem processes by comparing the direct and indirect effects of brook trout on aquatic-terrestrial linked food webs to those exhibited by native cutthroat trout. To accomplish this, he is using a combination of field experiments and multi-scale comparative studies. The results of this research will provide managers with a better understanding of how nonnative brook trout and native cutthroat trout interact with aquatic biota, identify possible indirect effects of brook trout on terrestrial organisms, and lead to and understanding of the true effects of nonnative trout in general.
