Research Interests:
Family-based genetic association and linkage disequilibrium methods, Bayesian methods in genetic analysis, genetic epidemiology, population structure, likelihood-based inference.
Dr. Varghese George joined the Medical College of Georgia in 2005 as Professor and Chair of the Department of Biostatistics. Dr. George has a well-established track record of methodological and collaborative research in Biostatistics, Statistical Genetics and Genetic Epidemiology, which started with his doctorate in Statistics from the University of Missouri-Columbia followed by his post-doctoral fellowship in Statistical Genetics at the Louisiana State University Medical Center in New Orleans under Professor Robert Elston. He continued his career as faculty in the Department of Biometry and Genetics at LSUMC, in the Division of Biostatistics at the Medical College of Wisconsin (MCW), and in the Department of Biostatistics at the University of Alabama at Birmingham (UAB). His primary methodological focus at present is on family-based association and linkage disequilibrium methods, population structure and Bayesian methods in genetic analysis. He is the recipient of several NIH-funded grants as Principal Investigator or Co-investigator. Dr. George has extensive experience in the academic world as an administrative leader, a scientist, a mentor, and an educator. During his tenure at UAB and MCW, he was the Director of Graduate Programs in Biostatistics at both places. Also, while at UAB, Dr. George served as the Director of a NIAMS-funded Annual Short course in Statistical Genetics, as the Co-Director of a NHLBI-funded post-doctoral training program in Statistical Genetics and as the Co-Director of a NIDDK-funded Annual Short Course in Statistical Genetics.
Teaching Areas: Graduate teachings in Biostatistics include Probability, Statistical Inference, Statistical Models and Methods, Nonparametric Statistics, Clinical Trials, Likelihood Principle, Applied Regression, Longitudinal Data Analysis, Statistical Genetics, Bayesian Inference, and Advanced Theory of Inference. Other teachings include Biostatistics for Medical Students and MS students in other Health Sciences areas.
