"I like to take two approaches to finding the 'best method' for solving aproblem. One tries to devise an efficient algorithm for the problem, and the other tries to establish limits on the efficiency of the algorithm."

Biography

Dorit S. Hochbaum is a full professor at UC Berkeley. She is a professor of Business Administration and of Industrial Engineering and Operations Research (IEOR). Professor Hochbaum holds a Ph.D from the Wharton school of Business at the University of Pennsylvania. Prior to joining UC Berkeley in 1981, Profeesor Hochbaum held a faculty position at Carnegie Mellon university's GSIA. Her research interests are in areas of supply chain management, efficient utilization of resources, computer algorithms and discrete optimization. She did work on locations of plants and bank accounts; on movement of robots; on routing and distribution problems; on feasibility of VLSI designs; on distribution of data bases on computer networks; on clustering problems and on layout and scheduling problems among others. She has contributed to the analysis of heuristics and approximation algorithms in the worst case, and on the average, and to the complexity analysis of algorithms in general, and nonlinear optimization algorithms in particular. Her recent applications work is on problems related to the semiconductor industry in layout, scheduling and testing, in production planning and supply chain streamlining for high tech industries and in logistics and planning problems in various industries. Recent theoretical work focuses on particularly efficient techniques for network flow related problems and inverse problems.

Professor Hochbaum served as the chair of the Manufacturing and Information Technology group at the Haas School of Business. She is the founder and director of the UC Berkeley Supply Chain Initiative. She is the founder and co-director of the RIOT project.

Professor Hochbaum is the author of over 90 papers that appeared in the Operations Research, Management Science and Theoretical Computer Science literature. She serves as department editor for Management Science department of Optimization and Modelling and on the editorial board of Networks. She served in the past on the editorial boards of Operations Research and Operations Research Letters.
