Integrating Cyber Innovations with Physical World

Dr. Shangping Ren is a Full Professor at the Department of Computer Science, Illinois Institute of Technology. She obtained her Ph.D in CS from UIUC in 1997. Before she joined IIT in 2003, she worked as a software engineer in industry for over five years. Her main research interest is in the areas of cyber-physical systems, real-time scheduling and cloud computing with focus on safety improvement of medical cyber-physical systems, software architecture and development, system reliability analysis under resource constraints, scheduling algorithm design for meeting reliability and deadline requirements, and resource optimization under cloud environment. She is one of the organizers for the first and second international workshop on Cyber-Physical Systems. The workshop now becomes the international conference on CPS. Her research is funded by NSF, Air Force Research Laboratory and Fermi National Accelerator Laboratory.
