"Robust Optimization in Engineering Design"

Abstract: In principle, complex systems can be optimized to improve performance with respect to desired functionalities. There is numerous evidence showing that if possible errors are not taken into account during the design process, we might lose the actual phenomenon. With this in mind, the eld of robust optimization started within the mathematical programming community. Most results, however, were con ned to problems with convex objectives. But modern engineering problems have objectives and constraints that are not explicitly given, e.g. numerical simulations describing the problem. In this talk, I will describe the recent advancements in this eld which allowed to bridge the gap and provided methods for generic robust design. Because of their generality, the presented methods can be applied to a wide range of engineering design problems. I will discuss three examples: in nanophotonic antenna design, ultrafast optics using chirped mirrors, and in cancer treatment with intensity modulated radiation therapy. Surprisingly, the robust solutions in question come at a fairly low price indicating that the advantages are worth the negligible sub-optimality.

Bio: Prof. Omid Nohadani is an Associate Professor in the department of Industrial Engineering and Management Sciences at Northwestern University since September 2013. Prior to that, he was an Assistant Professor of Industrial Engineering and the graduate advisor for Computational Science and Engineering at Purdue University since January 2010. His research focuses on robust optimization problems arising in a variety of settings: statistics, nano-technology, ultrafast optics, cancer radiation therapy, high-performance computing and vehicle routing. More recently, his interests have focused on the area of healthcare engineering, both from the methodological as well as treatment design aspect. He received a Diploma degree (equivalent to M.S.) in mathematical physics from the University of Bonn, Germany and a Ph.D. in physics from the University of Southern California. He was a postdoctoral researcher at the Operations Research Center at MIT from 2006 until December 2009 as well as a research fellow and instructor at Harvard Medical School from 2007 until 2009.
