Geoff Potvin completed his doctorate in theoretical physics at the University of Toronto before taking up a science education postdoctorate in the Curry School of Education at the University of Virginia. Prior to coming to FIU in January 2014, he spent five years as a faculty member in the Department of Engineering & Science Education at Clemson University. He is a member of the APS Forum on Education's Executive Committee and the American Association of Physics Teachers' Committee on Diversity. His research is focused on understanding diversity issues in the physical sciences and engineering at the undergraduate and graduate levels. Using an identity lens, he studies how educational practices and other experiences influence students' attitudes and career intentions, especially for those who are traditionally marginalized from STEM. He is working with the APS Bridge Program to understand how departmental admissions and retention practices can help to grow a more diverse body of future physicists, and the factors that affect student success in graduate physics.
