I am an Associate Professor in the Division of Biostatistics of the Department of Preventive Medicine at the University of Southern California (USC). My work focuses on on statistical methods and applications in environmental epidemiology and exhaled breath biomarkers. I lead an NIEHS-funded R01 on statisical methods for exhaled nitric oxide and I lead the statistical group working on methods for sensor-based, integrated health monitoring systems for measuring environmental, physiological, and behavioral factors in epidemiological studies of asthma in children.
