I received my M.Sc. degree in Statistics from University of Mysore, Mysore, India, in 1974, and Ph.D. degree in Statistics from Iowa State University, Ames, in 1980.  I have been at Ohio State ever since.  I am interested in order and record statistics, general distribution theory, applied probability models, and biostatistical applications.
