As an educator and ecologist, I am intrigued by the natural world, perplexed by the impact humans are having on it, and optimistic that we can change course. Research in the Theobald Lab focuses on equity in higher education STEM classes. We use quantitative and sometimes qualitative approaches to: 1) describe inequities; 2) identify instructor and systemic practices that disrupt inequities; and 3) scale equitable practices to all classes in all STEM disciplines.
