The lung is constantly exposed to various environmental pollutants, allergens, and toxins, which interact with airways and alveoli and result in inflammation, injury, and disease. My laboratory primary research interest has been centered on the paradigm that respiratory exposures to pollutants and toxicants contribute to development and progression of chronic lung diseases, and may further yield systemic effects well beyond lungs. Under this paradigm, my research activities have focused on understanding the physiologic and immunologic mechanisms via which environmental exposures contribute to chronic lung diseases and how knowledge of these mechanisms could be translated to ways to better define, prognosticate, and manage disease burden at both individual and societal levels.
I have dedicated my efforts to (1) investigate the biology of airway immune cells using inhalational exposure to ozone in humans as a model of lung injury simulating exacerbation in chronic lung disease, and (2) characterize the early cardiopulmonary changes due to exposure to tobacco smoke and the pathophysiology and biology associated with those changes.
