Biography

M. A. Pai. born on 5 October 1931 in the south Indian state of Karnataka, did his graduate studies in electrical engineering at the University of Madras and after completing the course in 1953, started his career as an electrical engineer at the Electric Supply Department of Brihanmumbai Electric Supply and Transport, then known as Bombay Electric Supply and Transport (BEST) Undertaking. After a service of 4 years, he moved to the US in 1957 where he completed his master's degree in electrical engineering (MS) at University of California, Berkeley in 1958 and continued at the institution to secure a PhD in 1961. Subsequently, he joined the university as an assistant professor at University of California, Berkeley (1961-62) before taking up Professorship at University of California, Los Angeles (UCLA) in 1962. At UCLA, he had the opportunity to work with Eliahu I. Jury, a Rufus Oldenburger laureate on discrete time systems, and in 1963 he returned to India to join the Electrical Engineering department of the Indian Institute of Technology, Kanpur as an assistant professor. He served the institute till 1981 during which period he held the positions of an associate professor from 1966 to 1969 and a professor thereafter till he went back to the US as a visiting professor at University of Illinois at Urbana-Champaign in 1981. He also had a stint as a consultant to the Uttar Pradesh Power Corporation Limited from 1971 to 1979. After two years of service as a visiting faculty at Illinois, he became a regular professor in 1983 and served out his academic career to superannuate in 2003. In between, he also served as a visiting professor at the Memorial University of Newfoundland and Iowa State University and visited India on a CSIR-UNDP program at Central Power Research Institute. Post-retirement, Illinois University made him an emeritus professor. He also serves as a consultant to Pacific Northwest National Laboratory, advising them on Model Reduction and Dynamic Security of Power System.

Legacy

Pai's early researches were based on power system stability, security and model reduction and his work on Model Reduction of Large-Scale Power Systems has been reported to be of significance to field of power systems. He is known to have introduced Lyapunov's method in researches on power system stability and energy functions. Introduction of computer applications in power systems is another of his contributions and a power system software he has developed is in use with several power distribution networks. Later, he worked on Smart Grid, Microgrid and Renewable Energy and how they could be integrated into the main electrical grid of a power system; earlier, at IIT Kanpur, he encouraged research on Control and Power. He has also contributed in the field of industrial consultancy and has served as a member of the editorial boards of Power and Energy series of Springer.

In 1963, Pai was selected to join IIT Kanpur as one of the earliest member of the Electrical Engineering faculty. Under the guidance of economist John Kenneth Galbraith, IIT Kanpur became the first institute in India to offer Computer science education. The earliest computer courses were started at IIT Kanpur in August 1963 on an IBM 1620 system, which was flown from Princeton to Kanpur. The initiative for computer education came from the Electrical engineering department. An intense outreach program in Computer Education was established during his time at IIT Kanpur. It was during his years at IIT Kanpur, Pai published his first book, Computer Techniques in Power System Analysis. His second book, Power System Stability: Analysis by the Direct Method of Lyapunov, was also published before he moved to US in 1981. This was followed by five more authored books, Com Tech In Power Sys Ana, Power System Dynamics and Stability, Power Circuits and Electromechanics, Energy Function Analysis for Power System Stability and Small Signal Analysis of Integrated Power Systems, the last one published in 2016. In between, he co-edited an Oxford University Press festschrift on Homi J. Bhabha titled Homi Bhabha and the Computer Revolution, which was featured in the Indian edition of MIT Technology Review in May/June 2011. He has also contributed chapters to books published by others and has authored over 125 peer-reviewed articles; the online article repository of Indian Academy of Sciences has listed 107 of them. He is reported to have helped organize two symposia of International Federation of Automatic Control in India and has delivered keynote or invited speeches at several science seminars in India and abroad including the Seminar on Voltage Instability in Power Network organized by the Delhi chapter of the Institute of Electrical and Electronics Engineers in 1991. He has also mentored a number of doctoral scholars in their studies.
