 Graduate Students

Michaela Woods (BS, MS), PhD Student

Michaela Woods completed her BS in Biological Sciences at Wright State University in 2016 and her MS in Biological Sciences (December 2018) also at Wright State University.  During her MS Michaela focused on soil ecology in relationship to Amur honeysuckle invasion in Dr. Megan Rua’s lab.  As a PhD student in the McEwan Lab Michaela is aiming to investigate the interconnections between soil biology, plant invasion, and ecological restoration in Midwestern Forests.  She is particularly interested in collaboration with the Five Rivers Metroparks which manages 16,000+ acres of natural areas in the Dayton Area.
