Staff Members

Erica Clites, Oakland County CISMA Director
Erica is a Michigan native who spent 10 years in California and Arizona getting a Master’s degree in Geology, running a field monitoring program for the National Park Service and managing a national collaboration of nine museums digitizing fossil clams and snails. Now Erica is excited to apply her natural resource training and love of partnership projects to the work of the Oakland County CISMA in preventing the spread of invasive species in Michigan’s second-most populous county.  Erica enjoys hiking, biking and cross-country skiing as well as taking her dog for walks in natural areas.

Emily Messick, Oakland County CISMA Technician
Emily has experience in aquatic ecology in Michigan and holds a Bachelor’s degree in Biology. She is also working on her Master’s degree in Biology/Aquatic Ecology from Oakland University. Her thesis project focuses on the utilization of cotton fabric as a means of measuring organic-matter decomposition in streams in the Upper Peninsula of Michigan. With experience in aquatic fieldwork, she spends her time with CISMA surveying for aquatic invasive species, like the newly invasive European Frogbit. In her spare time, Emily likes to travel to Michigan’s parks for camping, hiking, kayaking, biking, and some occasional bird-watching.
