About Me

I am currently a Professor of Biostatistics and Data Science at the Wake Forest School of Medicine and a Fellow of the American Statistical Association. I have a Ph.D. in Statistics from Harvard University and am currently the Director of the Clinical Research Management Graduate Program and the Director of the Biostatistics Shared Resource of the Comprehensive Cancer Center.  

During my 25+ years at Wake Forest School of Medicine, I have served as the Principal Investigator on federally funded grants and contracts with awards totaling over 25 million dollars. For example, I served as the Director/Co-Director of the Coordinating Center for the CDC/NIDDK funded SEARCH for Diabetes in Youth Study. This is a study of childhood/young adult diabetes that was conducted from 2001-2021. 

I have also served on numerous review panels, advisory boards, and data safety-monitoring committees for the NIH, FDA, and pharmaceutical industry.  

I have over 350 published manuscripts and book chapters in areas of clinical research, statistical methodology, cardiovascular disease, diabetes, and cancer.  

My areas of statistical expertise are primarily in the design and analysis of clinical trials, observational studies and large scale epidemiologic studies. Three areas of particular interest are:

  1. propensity score methods;
  2. methods for handling missing data in research studies, and 
  3. the development of predictive analytical models for outcomes in various diseases.  

I have served on six different editorial boards for medical/statistical journals, and am a co-inventor listed on several United States Patents. 

In addition to my research interests described above, I have been teaching online graduate classes in Research Design and Data Analysis for the students in the Clinical Research Management Graduate Program.
