My dissertation work is focused on the implementation of UDL within post-secondary physics and chemistry courses. Over the past two years, I have interviewed 19 students with disabilities on their experiences in post-secondary courses, particularly those considered STEM. This information was then used to train and support physics faculty and chemistry teaching assistants in UDL implementation. I have also supported the analysis of how aligned popular physics curriculum are with UDL. I have presented two professional talks at the American Association of Physics Teachers Conference on UDL and students with disabilities. A smaller subset of this information from this proposal was presented in a poster presentation at the Physics Education Research Conference.
