Steve Kroiss has a Ph.D. in Biology from Washington University in St. Louis and a B.S. in Biology from the University of Wisconsin Madison. For his postdoctoral work at the University of Washington in Seattle, he studied the effects of climate change on the geographic range boundaries and population dynamics of forests on Mt. Rainier. For his dissertation, he studied the effectiveness of different land management strategies for restoring rare plant populations in the Ozark Mountains and on the California coastline. He also worked at the Chicago Botanic Garden and consulted for Point Reyes National Seashore, helping to monitor and manage rare plant species. As an Education Research Fellow at the Center for Integration of Research, Teaching and Learning, he helped develop evidence-based teaching methods for improving students’ understanding of primary research articles. As a Teaching Associate at UW Seattle, he helped formulate several courses in ecology and statistical modeling. Additionally, he led a volunteer teaching team in the Young Scientist Program, a science outreach program for public school students. Steve has joined the Polio team as a research scientist to support polio eradication efforts by creating and improving statistical risk models, mapping disease spread, and analyzing vaccination campaign data.
