Biography

My primary research is as an applied statistician/biostatistician working on collaborative projects. I greatly enjoy the opportunity this affords me to learn new things about many different fields and disciplines. A very small sample of research I have had the fortune to support includes perinatal outcomes, diabetes, physical fitness, physical therapy, orthopedic surgery, anesthesia, infectious disease spread and diagnosis, sports analytics, traumatic brain injury and heart disease. I have particular interest in statistical modeling of categorical data, logistic regression, and survival analysis. Additional research interests involve statistical and mathematical education. A particularly fun aspect of this latter pursuit is the use of games for teaching statistics.

I am a retired U.S. Army Colonel, and served on active duty for 27-years after graduating from West Point. I completed my military service at West Point after I was selected as an Academy Professor. During this time, I founded and directed the West Point Center of Data Analysis and Statistics (CDAS) and earned the academic rank of Professor of Applied Statistics. After retirement I spent time as Associate Professor of Clinical Public Health in the Biostatistics Division of the College of Public Health at The Ohio State University, where I also served briefly as Chair for Biostatistics. I then took a position as Professor at Azusa Pacific University, building and directing a new M.S. in Applied Statistics and Analytics. Most recently, I worked as a research biostatistician for the Henry M. Jackson Foundation for the Advancement of Military Medicine supporting research at the Uniformed Services University of Health Sciences. I am married to Mandy and have two children: Chelsea (Grove City College, 2009), and Steven (Baylor, 2016). Chelsea has two sons, Erik and Marcus. I enjoy playing the violin and running, not at the same time.
