The introductory lab can be a critical space for the development of students’ skills, understandings, and interest in physics. My research focuses on developing and evaluating new learning materials and instructor professional development for introductory physics labs. I’m interested in questions like: How can the introductory physics lab be made equitable and supportive for traditionally-marginalized students? What does successful professional development for lab TAs look like? What does it take to make meaningful inquiry learning work in our introductory labs?
