Mac graduated in 1993 from Bowdoin College in Brunswick, Maine, with a Bachelor’s degree in Physics. He earned his Ph.D. in physics at the University of Pennsylvania in Philadelphia. After working at the University of Washington as a Postdoctoral Research Associate and Research Assistant Professor in Physics Education Research for almost 10 years, Mac joined the Physics Education Research Laboratory in Fall 2011.

Since 2001, Mac has been deeply involved in developing research-based and research-validated instructional materials for undergraduates and K-12 teachers. His current research interests include TA and K-12 teacher ability to assess student understanding, the professional development of TAs and future physics faculty, as well as student understanding of topics such as electric circuits and mechanical waves.

Over the past few years, a primary focus of Mac’s work has been an in-depth investigation of student understanding of analog electronics, primarily in the context of upper-division laboratory courses on the topic. In addition to identifying specific conceptual difficulties and examining the impact of such courses on student learning, he is leading the collaborative development of research-based instructional materials for use in these upper-division courses.
