He holds joint appointments in the Departments of Electrical & Computer Engineering and Computer Science as well as the Coordinated Science Laboratory (CSL), the National Center for Supercomputing Applications (NCSA), and the Carl R. Woese Institute for Genomic Biology. The winner of numerous awards and honors, he was the founding chief scientist of the Information Trust Institute at UIUC—a campus-wide research center addressing security, reliability, and safety issues in critical infrastructures. Zbigniew T. Kalbarczyk is a Research Professor in the Department of Electrical & Computer Engineering and the Coordinated Science Laboratory of the University of Illinois Urbana-Champaign, USA. He is a member of the IEEE, the IEEE Computer Society, and IFIP Working Group 10.4 on Dependable Computing and Fault Tolerance. Dr. Kalbarczyk’s research interests are in the design and validation of reliable and secure computing systems. His current work explores emerging computing technologies, machine learning-based methods for early detection of security attacks, analysis of data on failures and security attacks in large computing systems, and more. Nithin M. Nakka received his B. Tech (hons.) degree from the Indian Institute of Technology, Kharagpur, India, and his M.S. and Ph.D. degrees from the University of Illinois Urbana-Champaign, USA. He is a Technical Leader at Cisco Systems and has worked on most layers of the networking stack, from network data-plane hardware, including layer-2 and layer-3 (control plane), network controllers, and network fabric monitoring. His areas of research interest include systems reliability, network telemetry, and hardware-implemented fault tolerance.
