Anuradha Roy holds a Ph.D. in applied statistics from Oakland University in Michigan, an M.Stat. in advanced probability and mathematical statistics from the Indian Statistical Institute and a B.Sc. in mathematics from Calcutta University (Presidency College) in India.
Professor Roy’s research interests include developing classification rules for multi-level multivariate data with structured mean vectors and structured covariance matrices. She also works on linear models for multi-level multivariate data. As an applied statistician she has a passion to work with applied problems. Areas of application include medical and biomedical sciences and engineering applications.
Professor Roy’s research has appeared in numerous journals including Computational Statistics and Data Analysis, Journal of Statistical Planning and Inference, Statistics in Medicine, Biometrical Journal, Bone and Journal of Clinical Oncology, as well as a book chapter. She has reviewed three scholarly books, including the recent 2011 Negative Binomial Regression by Joseph M. Hilbe.
