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).

Projects
DataDepot, DataDepot and its associated toolchain enable the fast construction and easy maintenance of very large real-time stream warehouses.
