• Ph.D. in Biology from University of Wisconsin–Milwaukee
• B.S. in Biology from University of Wisconsin–Milwaukee

His research focuses on cryptic biological diversity in seedless plants like mosses and ferns, particularly at species-to-population levels within polyploid complexes. He also investigates functional trait evolution, genome duplication events, and the ecological dynamics of Great Lakes peat-accumulating wetlands through bryophyte documentation.

As Herbarium Curator, he maintains botanical collections at the Cofrin Center for Biodiversity. When not working, he engages in field botany and natural history studies.
