I spent my childhood in Amritsar, India, also known as the city of the Golden Temple. I received my B.E. degree in Computer Science Engineering from Motilal Nehru Regional Engineering College, Allahabad, India in 1983. I then worked with Engineers India Limited for three years. I received my M.S. (Computer Science) from the University of Arkansas, Fayetteville in 1987, and Ph.D. (Computer Science) from the University of Nebraska, Lincoln in 1991. Since Fall 1991, I have been with the Department of Mathematics & Computer Science at the University of Missouri at St. Louis . In between, I spent a year (2002-03) at Southern Illinois University Edwardsville. I have published in the areas of human face perception, image databases, knowledge acquisition, machine learning, and information retrieval. I am also interested in computer security. I am a member of ACM and AAAI.
