Joseph M. Hellerstein (born 7 June 1968[1]) 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,[2][3] adaptive query processing,[4] approximate query processing and online aggregation,[5] declarative networking, and data stream processing.[6]
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. He is a Fellow of the Association for Computing Machinery (2009).[7] 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.
