Hudson Professor of Electrical and Computer Engineering, in the Edmund T. Pratt, Jr. School of Engineering, he is head of Duke High Availability Assurance Laboratory (DHAAL). He holds the Hudson Chair in the Department of Electrical and Computer Engineering at Duke University, in Durham, North Carolina. He has been on the Duke faculty since 1975. He received his B.S.E.E. degree from the Indian Institute of Technology (India) in 1968; his M.S. degree in 1972 and his Ph.D. in 1974, both from the University of Illinois, Urbana-Champaign. He is known as a leading international expert in the domain of reliability and performability evaluation of Dependable systems, and has made seminal contributions to stochastic modeling formalisms and their efficient solution. He is currently carrying out experimental research in software reliability during operation where he is researching software fault tolerance through environmental diversity. This work, including software bug classification, empirical study of real failure data and associated theory of affordable software fault tolerance, has already gained significant attention. He has made key contributions to his field in many ways. He has encapsulated developed algorithms into usable and well circulated software packages, and applied research results to practical problems working directly with industry. This work has not only been able to solve difficult real-life problems but also produce new research based on the problems. He has published over 500 articles, has supervised 45 Ph.D. dissertations and more than 30 postdoctoral associates. He is a Fellow of the Institute of Electrical and Electronics Engineers and a Golden Core Member of IEEE Computer Society. He has served on many editorial boards and conference committees and is the recipient of IEEE Computer Society 2008 Technical Achievement Award Recipient, "For pioneering contributions to the understanding of the phenomena of software aging and software rejuvenation". He is on ISI?s highly cited list with an h-index of 82, and has received grants from such governmental agencies as NASA, NATO, NSF, DARPA, AFOSR, ARO, NIH, NSWC, ONR, and RADC. He has also helped several high-profile companies carry out reliability/availability prediction of their products under design or in existence, including 3Com, Avaya, Boeing, Cisco, DEC, EMC, GE, HP, Huawei, IBM, Lucent, NEC, TCS, Union Switch and Signals, Wipro. Most notable among these, is his help in reliability modeling of the current return network subsystem of the Boeing 787 for FAA certification. The algorithm he developed for this problem has been jointly patented by him and Boeing. He led the reliability/availability modeling of SIP on IBM WebSphere; this model was responsible for the sale of the system by IBM to AT & T. Furthermore, he has written several influential books, including textbooks. He is the author of a well-known text entitled, Probability and Statistics with Reliability, Queuing and Computer Science Applications, originally published by Prentice-Hall; a thoroughly revised second edition (including its Indian edition) has been published by John Wiley. He has also published two other books titled, Performance and Reliability Analysis of Computer Systems, published by Kluwer and Queueing Networks and Markov Chains, John Wiley. He is completing a new book on Reliability and Availability Engineering for Cambridge University Press. He is the author or co-author of several publications including: with Mondal, S.K., Yin, X., Muppala, J.K., and Alonso Lopez, Defects per Million Computation in Service-Oriented Environments, IEEE Transactions on Services Computing, vol 8 no. 1 (2015), pp. 32-46 [10.1109/TSC.2013.52] [abs]; with Yin, X., Ma, X., and Vinel, A., Performance and Reliability Evaluation of BSM Broadcasting in DSRC with Multi-Channel Schemes, IEEE Transactions on Computers, vol 63 no. 12 (2014), pp. 3101-3113 [10.1109/TC.2013.175] [abs]; with Sebastio, S., Wang, D., and Yin, X., Fast computation of bounds for two-terminal network reliability, European Journal of Operational Research, vol 238 no. 3 (2014), pp. 810-823 [10.1016/j.ejor.2014.04.035] [abs]; with Ghosh, R., Longo, F., Xia, R., and Naik, V.K., Stochastic Model Driven Capacity Planning for an Infrastructure-as-a-Service Cloud, IEEE Transactions on Services Computing, vol 7 no. 4 (2014), pp. 667-680 [10.1109/TSC.2013.44] [abs]; and with Xia, R., Yin, X., Alonso Lopez, J., and Machida, F., Performance and Availability Modeling of ITSystems with Data Backup and Restore, IEEE Transactions on Dependable and Secure Computing, vol 11 no. 4 (2014), pp. 375-389 [10.1109/TDSC.2013.50] [abs]. In addition, he has published two books entitled, ?Performance and Reliability Analysis of Computer Systems?, published by Kluwer Academic Publishers and ?Queueing Networks and Markov Chains?, John Wiley; second edition published in 2006. He has also edited two books, Advanced Computer System Design, published by Gordon and Breach Science Publishers, and Performability Modeling Tools and Techniques, published by John Wiley & Sons.
