Biography

Joseph M. Hellerstein is a Professor of Computer Science at the University of California, Berkeley, whose work focuses on data-centric systems and the way they drive computing. He is an ACM Fellow, an Alfred P. Sloan Research Fellow and the recipient of two ACM-SIGMOD "Test of Time" awards for his research. In 2010, Fortune Magazine included him in their list of 50 smartest people in technology , and MIT's Technology Review magazine included his work on Distributed Programming on their 2010 TR10 list of the 10 technologies "most likely to change our world". Key ideas from his research have been incorporated into commercial and open-source software from IBM, Oracle, and PostgreSQL. He is a past director of Intel Research Berkeley, and currently serves on the technical advisory boards of a number of computing and Internet companies.
