My methodologic research is to develop statistical models that support scientific learning about human health. My earlier work was on regression models for correlated responses that arise when observations come in clusters, for example in longitudinal research or in sample surveys or when when data are observed over time or space. We have extended generalized linear models (logistic, linear, log-linear and survival models) to be applicable in these cases. More recently, my work has been on Bayesian models for the etiology of childrens pneumonia and on methods for precision medicine, an expanded vision of which at Johns Hopkins we call "individualized health".
