Area of Interest

 Respiratory Immunology & Toxicology

 The main goal of my laboratory is to determine if exposure during early life to environmental factors (i.e. allergens, pollutants, and respiratory viruses) leads to predisposition, development of, or exacerbation of respiratory disease in the adult. We believe that adult respiratory diseases result, in part, from environmental impacts that occur during a critical phase of immuno-maturation. In the short term, we seek: (1) to define the cellular and molecular changes in the pulmonary microenvironment following gestational and/or neonatal exposure; (2) to determine if urban pollutants (e.g. particulates such as diesel exhaust particles), initiate cellular/molecular events in the developing lung which lead to increased susceptibility to airways disease later in life; (3) to define the impact of respiratory viral infection on pulmonary pathophysiology of the infant; and (4) to understand how urban pollutants impact host defense resulting in enhanced morbidity and increased mortality from respiratory infections.

 The long-term objective of my laboratory is to realize the initiators of the immune and pathophysiological changes that occur during the early stages of pulmonary airways disease and ultimately to develop effective interventions and therapies.
