Dr. Larson-Casey research interests focus on environmental toxins and the critical role of lung monocytes and macrophages within chronic pulmonary diseases. Dr. Larson-Casey studies include investigating the macrophage subset and mechanism(s) by which environmental toxins (fine particulate matter, cadmium, asbestos) regulate the development and progression of chronic lung diseases by focusing on macrophage/monocyte redox signaling, mitochondrial bioenergetics, and immunometabolism.
