About me

I received my Ph.D. in Statistics from the Department of Statistics at the University of North Carolina at Chapel Hill in 1987 under the direction of Raymond J. Carroll . My interests include statistical methods for estimating optimal treatment regimes from data; methods for analysis of clinical trials and observational studies, including approaches for drawing causal inferences; statistical models and methods for analysis of longitudinal data, especially nonlinear mixed effects models; methods for handling missing and mismeasured data; and pharmacokinetic and pharmacodynamic analysis. In addition to my position here at NCSU, I have a position as Adjunct Professor of Biostatistics and Bioinformatics at Duke University, and I collaborate with clinicians and biostatisticians at Duke Clinical Research Institute on problems in cardiovascular disease research.
