Biographical sketches of authors

Keith Whisnant Center for Reliable and High-Performance Computing, University of Illinois at Urbana-Champaign, 1308 W. Main Street, Urbana, Illinois 61801 (electronic mail: kwhisnan@crhc.uiuc.edu). Mr. Whisnant is currently a Ph.D. student at the University of Illinois. He holds a B.S. and an M.S. degree in computer engineering, also from the University of Illinois. While in graduate school, he has been the lead architect and system designer for the Chameleon ARMORs project, which uses a reconfigurable software infrastructure to provide a wide variety of fault-tolerant services to user applications. He has worked with the Jet Propulsion Laboratory in applying the ARMOR concepts to a software-implemented fault-tolerant environment for protecting parallel scientific applications that execute in space.

Zbigniew T. Kalbarczyk Center for Reliable and High-Performance Computing, University of Illinois at Urbana-Champaign, 1308 W. Main Street, Urbana, Illinois 61801 (electronic mail: kalbar@crhc.uiuc.edu). Dr. Kalbarczyk is currently Principal Research Scientist at the Center for Reliable and High-Performance Computing in the Coordinated Science Laboratory of the University of Illinois at Urbana-Champaign. He holds a Ph.D. in computer science. After receiving his doctorate, he worked as Assistant Professor in the Laboratory for Dependable Computing at Chalmers University of Technology in Gothenburg, Sweden. Currently he is one of the leading researchers on the project to explore and develop approaches and techniques for providing an adaptive software infrastructure that allows different levels of availability requirements to be supported in a network environment. Dr. Kalbarczyk's research also involves developing automated fault/error injection techniques for validation and benchmarking of dependable and secure computing systems. He has served as a program co-chair of the International Performance and Dependability Symposium (IPDS), a track of the Conference on Dependable Systems and Networks (DSN 2002), and is regularly invited to work on the program committees of major conferences on design of fault-tolerant systems.

Ravishankar K. Iyer Center for Reliable and High-Performance Computing, University of Illinois at Urbana-Champaign, 1308 W. Main Street, Urbana, Illinois 61801 (electronic mail: iyer@crhc.uiuc.edu). Professor Iyer is Director of the Coordinated Science Laboratory (CSL) at the University of Illinois at Urbana-Champaign, where he is 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. He is Co-Director of the Center for Reliable and High-Performance Computing at CSL. His research interests are in the area of reliable networked systems. He currently leads the Chameleon ARMORs project at the University of Illinois, which is developing adaptive architectures for supporting a wide range of dependability and security requirements in heterogeneous networked environments. Professor Iyer 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.”
