My work in physics education research focuses on the modeling of student learning of physics. Presently, I am investigating student reasoning about quantum physics and advanced mechanics and the role of everyday knowledge in understanding highly abstract and seemingly
counter-intuitive ideas. I have also studied student reasoning about
mechanical waves, sound, the use of mathematical reasoning in physics, the assessment of large-scale reform of laboratory courses in physics, and the analysis of common research tools within physics education research.

In my teaching, I use research-based small group activities, large-group interactive lectures, and modeling laboratories for introductory physics, advanced physics, and pre-service and in-service teachers. I also teach educational psychology courses and courses in science education to non-science and non-education students. My work draws on both physics and other disciplines, including psychology, cognitive science, education, and human development.

I am an assistant professor in Physics and Astronomy and a cooperating assistant professor in the College of Education and Human Development. Also, I serve as director of the Physics Education Research Laboratory (http://perlnet.umephy.maine.edu/). We presently have 2 active faculty, several associated faculty, and 7 graduate students. Of these, 3 seek a Ph.D. in physics with a focus on physics education research, 2 seek an MST degree, and 2 seek both degrees.
