"We are in an exciting era in optimization research where a series of mathematical discoveries and algorithmic innovations, coupled with the advances in computer technology, make it possible to offer solutions to problems in a variety of areas, ranging from fleet logistics to electronic financial exchanges, from power systems design to genetics with massive data sets."


Alper Atamturk is a Professor of Industrial Engineering and Operations Research at the University of California, Berkeley. He received his Ph.D. from the Georgia Institute of Technology in 1998. His current research interests are in integer programming (conic, mixed, combinatorial), optimization under uncertainty with applications to power systems, portfolio/network design, logistics of production, distribution, transportation systems and treatments for cancer. He serves on the editorial boards of Operations Research, Mathematical Programming Computation, Discrete Optimization, Journal of Risk, and Networks; and has in the past served on the editorial board of Management Science. Dr. Atamturk is a National Security Science & Engineering Faculty Fellow of the US Department of Defense.
