He is a Fellow of the American Statistical Association, Fellow of the Institute of Mathematical Statistics and an Elected Member of the International Statistical Institute. His research interests include ordered data analysis, censoring methodology, univariate and multivariate distribution theory, reliability theory, and survival analysis.

He holds a Ph.D. in Biostatistics from the University of Michigan and his main research focuses on developing likelihood ratio tests in multivariate analysis and obtaining their exact distributions in closed finite form, whenever possible, or developing the so-called near-exact distributions for the other cases, which are sharp asymptotic distributions that are asymptotic for all parameters involved.
