Subject matter expert in Data warehouse, data stream, stream warehouse, data quality

I received a B.S in Mathematics from the Johns Hopkins University in 1986, and a Ph.D. in Computer Science from the Courant Institute of NYU in 1990., receiving the Janet Fabri award for best dissertation in the department.  From 1990 through 1996, I was an Assistant Professor, then Associate Professor, in the Computer and Information Science and Engineering department at the University of Florida.  In 1996 I joined the Database Research department of AT&T Labs - Research, abd have been here since.  In 2004 I received an AT&T Science and Technology for my work in the Bellman database browser.  I have authored two books, "Distributed Operating Systems & Algorithms" (with Randy Chow), and "Exploratory Data Mining and Data Cleaning" (with Tamraparni Dasu).
