General info

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 models and methods for analysis of longitudinal data, especially nonlinear mixed effects models; methods for handling missing and mismeasured data in statistical models; statistical methods for analysis of clinical trials and observational studies, including approaches for drawing causal inferences; pharmacokinetic and pharmacodynamic analysis; combining mechanistic mathematical and statistical modeling of disease progression to design treatment strategies and clinical trials; and statistical inference in general. In addition to my position here at NCSU, I have a position as Adjunct Professor of Biostatistics and Bioinformatics at Duke University, and I spend most Wednesdays at Duke Clinical Research Institute collaborating with clinicians and biostatisticians there on interesting problems in cardiovascular disease research.
