    Research Interests

    Basic Science Research: A major goal of my research is to understand the mechanisms and molecules that allow efficient protein folding in vivo. My efforts are focused on: (1) expanding our methodological arsenal to study the relationship between protein synthesis and folding in various model systems and (2) interrogating how protein misfolding leads to disease states, with particular emphasis on neurodegeneration.

    Medical and Graduate Education: My main interests are: (1) curriculum design to integrate foundational and clinical sciences based on contextual and causal relationships; and (2) streamlining methodologies to allow efficient incorporation of active learning methodologies into medical and graduate school curricula.
