Research Overview
Dr. Yan Ma is Assistant Professor of Biostatistics in the Division of Biostatistics and Epidemiology in the Department of Public Health at Weill Medical College of Cornell University.
He received his Ph.D. in Statistics from the University of Rochester in 2008. His research interests in statistical methodology center on inference for instrument reliability and rater agreement, nonparametric estimation and inference, observational studies, causal inferences, longitudinal data analysis, and missing data problems. His experience in applied medical research includes collaborative work on a series of NIH-funded HIV/AIDS, orthopedic, and suicide prevention studies. During his doctoral training, he successfully applied the novel approach proposed in his dissertation to addressing important issues on accuracy of proxy outcomes in patients with depression within a longitudinal data setting in the presence of missing data.
Currently, he is collaborating with investigators across the departments at the Hospital for Special Surgery, providing statistical consulting assistance in study design, grant proposal, and data analysis utilizing rigorous statistical methods. He has a particular interest in the field of national database outcomes associated with rare events such as perioperative death and a number of complications after orthopedic surgery. He was recently awarded a CERT (Center for Education and Research Therapeutics) pilot grant to study inference for Cronbach’s Coefficient Alpha from the Weill Medical College of Cornell University.
