Brett Hayhurst successfully defended his PhD on November 18, congratulations! His dissertation is on evaluating the largescale application of clean dredge material as effective in aquatic habitat restoration in the Great Lakes. His project encompasses the St Louis River Estuary near Duluth, Minnesota, one of the largest freshwater estuaries in the Great Lakes. He has been a graduate student at Cornell University as an employee of the US Army Corps of Engineering. His committee chair was Jim Watkins, and includes Lars Rudstam, Todd Walter (Biological Environmental Engineering) and Joe Kreitinger (retired US ACE). Brett intends to continue as an US ACE employee and to collaborate with our Great Lakes programs at Cornell University.
