Olivier L. de Weck, Ph.D., dipl. Ing., is an Associate Professor of Engineering Systems and Aeronautics and Astronautics at the Massachusetts Institute of Technology (MIT). He obtained his degree in Industrial Engineering from ETH Zurich in 1993 and SM and PhD degrees in Aerospace Engineering from MIT in 1999 and 2001, respectively. His research focuses on understanding how complex man-made systems evolve over time and how we can design them to be more changeable while maximizing lifecycle value. Prof. de Weck has developed quantitative and implementable methods and tools that explicitly consider both changeability and commonality. Specific examples of such methods are Time-Expanded Decision Networks (TDN), the Delta-Design Structure Matrix (DSM) and the Technology Infusion Analysis (TIA) process. He is an Associate Fellow of AIAA, and also serves as Associate Editor for the Journal of Spacecraft and Rockets. He won two best paper awards at he 2004 INCOSE Systems Engineering conference, the 2006 Frank E. Perkins Award for Excellence in Graduate Advising at MIT, a 2007 AIAA Outstanding Service Award and the 2008 best paper award from the journal Systems Engineering. Since July 2008 he serves as Associate Director of the Engineering Systems Division at MIT, an academic unit with 53 faculty members and senior staff as well as approximately 440 graduate students.
