Research Program
- To understand the pathologic basis of health effects caused by environmental and occupational air pollutants
- Using laboratory animal models of respiratory, cardiovascular, autoimmune and metabolic diseases to explore how chronic diseases effect susceptibility to toxicity caused by inhaled toxicants (ozone, particulate matter and silica dust)
- With the overall goal to experimentally elucidate cellular, molecular or biochemical targets for interventions to prevent (or treat) adverse effects caused by air pollution
- Genetic analysis of COVID-19 susceptibility and resistance determinants (e.g., pulmonary histopathology) in collaborative cross mice
Current Investigation
- Role of group 2 innate lymphoid cells (ILC2s) in air pollutant-induced, allergen-independent asthma and rhinitis
- Mechanisms of dietary lipid prevention/treatment for silica-induced autoimmunity
- Airway and systemic inflammatory/immune responses to short-and long-term exposures to ambient air pollutants individually or as mixtures
