I’m a science educator, teacher, and researcher. More specifically, I am an Associate Professor of science education at the University of Colorado Denver in the School of Education and Human Development. I currently teach pre-service and in-service science teachers, undergraduate peer Learning Assistants (LAs), and doctoral students. My research focuses on peer learning support in undergraduate science courses across the disciplines, although my experience and particular interest is in physics education research (PER). Prior to entering academia, I taught science in grades 7-12 for seven years in US public schools, primarily physics in 11th and 12th grade.
