Joseph M. Hellerstein is professor of Computer Science at the University of California, Berkeley, where he works on database systems and computer networks. After receiving a bachelors degree from Harvard University and a master's degree from UC Berkeley, he received his PhD from the University of Wisconsin, Madison in 1995, for a thesis on query optimization supervised by Jeffrey Naughton and Michael Stonebraker. He has made seminal contributions to many areas of database systems, such as ad-hoc sensor networks [Samuel Madden, Michael J. Franklin, Joseph M. Hellerstein, W. Hong: TAG: a Tiny AGgregation Service for Ad-Hoc Sensor Networks. 2002] [Samuel Madden, Michael J. Franklin, Joseph M. Hellerstein, W. Hong: The design of an acquisitional query processor for sensor networks. Proc. ACM SIGMOD International Conference on Management of Data, 2003] , adaptive query processing [Ron Avnur, Joseph M. Hellerstein: Eddies: continuously adaptive query processing. Proc. 2000 ACM SIGMOD International Conference on Management of Data, 2000.] , approximate query processing and online aggregation [Joseph M. Hellerstein, Peter J. Haas, Helen J. Wang: Online Aggregation. SIGMOD Conference 1997: 171-182.] , declarative networking, and data stream processing [Sirish Chandrasekaran, Owen Cooper, Amol Deshpande, Michael J. Franklin, Joseph M. Hellerstein, Wei Hong, Sailesh Krishnamurthy, Samuel Madden, Vijayshankar Raman, Frederick Reiss, Mehul A. Shah: TelegraphCQ: Continuous Dataflow Processing for an Uncertain World. Proc. CIDR 2003.] .

His work has been recognized via awards including an Alfred P. Sloan Fellowship, MIT Technology Review's inaugural TR100 list, and two ACM-SIGMOD "Test of Time" awards. Key ideas from his research have been incorporated into commercial and open-source database software released by IBM, Oracle Corporation, and PostgreSQL. He has also held industrial posts including Director of Intel Research Berkeley, and Chief Scientist of Cohera Corporation.
