Exhaled breath analysis is a unifying theme with ongoing work on exhaled gas and particle phase biomarkers for lung inflammation and studies of exhaled particles as the vehicle of airborne communicable disease transmission.Specialties: Airborne infection transmission, respiratory infection, occupational and environmental asthma, bioaerosols, endotoxin, occupational and environmental epidemiology.
