Patricia M Dieter
Patricia Dieter is a Biological Science Technician based in Ann Arbor, MI.
I began working with USGS as a contractor on the GLRI funded CSMI efforts on Lake Huron in 2012. This project involved researching foodweb energy transfer from nearshore to offshore waters. I continued this research on Lakes Erie and Michigan during their intensive field years in the CSMI cycle. I am now a Biological Science Technician maintaining involvement in CSMI as well as other projects at USGS.
