1986. He has been a Research Staff Member at the IBM Almaden Research
Center since 1987, where a major focus of his work has has been the application
of probabilistic and statistical techniques to database systems. He invented a
number of methods used by the DB2 query optimizer to estimate query
processing costs, as well as methods for estimation of catalog statistics that have
been incorporated into the DB2 RUNSTATS utility. He was a principal
implementor of the correlation analyis and linear regression functions in DB2
UDB, and helped provided similar functionality to the DB2 Warehouse Manager
product. He also developed technology for interactive online processing of
complex aggregation queries, and led an effort to develop a prototype "online
aggregation" interface to DB2. This work earned him the IBM Research Division
1999 Best Paper Award and an Honorable Mention at the 1999 ACM SIGMOD
conference. Recently, he has been leading an effort to provide sampling and
estimation functionality in DB2, and is helping to develop the proposed ISO
standard for sampling in SQL queries. He is a member of the Institute for
Operations Research and Management Sciences and is currently an Associate
Editor for the journal "Operations Research". Since 1999, he has been affiliated
