Ravishankar K. Iyer is the director of the Coordinated Science Laboratory (CSL) at the University of Illinois at Urbana-Champaign, where he is a George and Ann Fisher Distinguished Professor of Engineering. He holds appointments in the Department of Electrical and Computer Engineering and the Department of Computer Science and he is the codirector of the Center for Reliable and High-Performance Computing at CSL. His research interests are in the areas of dependable and secure systems. He has been responsible for major advances in the design and validation of dependable computing systems. His research focuses on methods and techniques for designing secure and fault tolerant networked systems and applications. He currently leads the ARMORs project at Illinois, which isdeveloping adaptive architectures for supporting a wide range of dependability and security requirements in heterogeneous networked environments. The goal is to provide hierarchical techniques to mask both reliability failure and security bugs via hardware, operating systems, and middleware in a way that can adapt dynamically to the specific, varying reliability and security requirements of applications. In addition to his strong research record, he also has a broad outreach to industry and government, both nationally and internationally, having worked with several major vendors over the years. He is a fellow of the IEEE and the ACM, and an associate fellow of the American Institute for Aeronautics and Astronautics (AIAA). He has received several awards including the Humboldt Foundation Senior Distinguished Scientist Award for excellence in research and teaching, the AIAA Information Systems Award and Medal for "fundamental and pioneering contributions towards the design, evaluation, and validation of dependable aerospace computing systems," and the IEEE Emanuel R. Piore Award "for fundamental contributions to measurement, evaluation, and design of reliable computing systems."
