She is the lead statistician for the Northwestern Juvenile Project, a large-scale longitudinal study of psychiatric disorders and risky behaviors in delinquent youth. Her work on the on the National Morbidity Mortality and Air Pollution Study (NMMAPS) used Bayesian methods to estimate generalized linear models with distributed lags to capture short term effects of air pollution on mortality.
