About

1. Dr. Akhilanand Pati Tiwari is a Visiting Faculty in the School of Computing and Electrical Engineering. Prior to coming to IIT Mandi, he served as Director, Knowledge Management Group at Bhabha Atomic Research Centre and Senior Professor, Electrical Sciences, Homi Bhabha National Institute, Mumbai, Department of Atomic Energy. Akhilanand did his B. S. Engineering from Aligarh Muslim University, Aligarh, India in 1984; Orientation Course in Nuclear Science and Engineering during September 1984 – July 1985 from the Bhabha Atomic Research Centre Training School Mumbai; and Ph. D. in Systems and Control Engineering from the Indian Institute of Technology Bombay, Mumbai, India in 2000. He was on deputation to Gesellschaft fuer Anlagen- und Reaktorsicherheit (GRS) GmbH (formerly known as Gesellschaft fuer Reaktorsicherheit), Garching, Munich, Germany during June 1988 to May 1989 (one year) to carry out research work in the area of ‘Reactor Dynamics Studies for Control Analysis.’ He visited International Atomic Energy Agency (IAEA) Headquarters, Vienna, Austria in 1999, 2009 and 2017 and Tokyo, Japan in 2007 to participate /give invited talks in Technical Meetings/Workshops. Akhilanand is recipient of the prestigious Homi Bhabha Science and Technology Award of the Department of Atomic Energy and Distinguished Faculty Award of the Homi Bhabha National Institute, Department of Atomic Energy. For his significant research and development contributions in engineering, he has been elected as Fellow, National Academy of Engineering (FNAE). Akhilanand’s research areas are Control and Estimation, especially the Singular perturbation and two time—scale methods, Large scale systems control, Multirate output feedback control, Sliding mode control, Kalman filtering, and Principal Component Analysis. He has successfully applied the control analysis and design techniques to small and large Nuclear Reactors.
