Prof Mahendra Singh Sodha popularly known as Prof M S Sodha has a distinguished record of achievements in the fields of educational management, scientific research, industrial consultancy and teaching; he has the distinction of serving three universities viz. Devi Ahilya Vishwavidyalaya Indore (MP), Lucknow University Lucknow (UP) and Barkatullah University Bhopal (MP) as Vice-Chancellor. He has also worked as Director of two self-financed engineering/management institutes (in India). Prof M S Sodha has also served Indian Institute of Technology Delhi (IITD) in various capacities, including Professor, Head of Department, Dean Post Graduate Studies and Deputy Director; he was also a Member of the Board of Governors for a term.

Besides extensive research at national and international levels and teaching at the undergraduate and postgraduate levels, Prof Sodha has worked as Chief of Space Physics at Republic Aviation Corporation, New York, U.S.A.; Senior Physicist at Armour Research Foundation, Chicago, USA and Visiting Scientist at the Solar Energy Research Institute, Golden Colorado, USA and Kuwait Institute of Scientific Research, Kuwait. He has also worked as Chief Technical Advisor with the World Bank/Cyprus Government and as a full-time consultant with UNESCO on Energy Planning and Conservation. He has also been a consultant to UNDP, Swedish Industrial Development Agency, Planning Commission and Solar Research Institute, U.S.A. Prof Sodha has served the University of British Columbia, Vancouver, Canada as a PDF, Visiting Professor at Drexel University, Philadelphia, USA and Senior Research Associate at NASA, Hampton, Va, USA.
He is a recipient of several prestigious awards like S S Bhatnagar Award given by CSIR (India) for Physical Sciences in 1974, Pioneer in Renewable Energy award by World Renewable Energy Network and UNESCO in 2002 and Dr K S Rao Memorial national award for lifetime achievement in renewable energy by SESI in 2004. He is one of the two first recipients of Saraswati Samman conferred by the U P Government. Besides being a Fellow of the Indian National Science Academy (INSA), New Delhi and the National Academy of Sciences (NASI) India, Allahabad, he has been President of the Optical Society of India, President of Plasma Society of India and Vice-President of Energy Society.
Prof M S Sodha is credited with having guided 75 candidates upto successful completion of their Ph D programme. In addition, he has authored/edited 15 books which were published by internationally reputed publishers like Plenum, Pergamon, Springer, John Wiley, etc. Most recent one was Kinetics of Complex Plasmas (Springer series in Atomic, Optical and Plasma Physics, 2014). He has also published over 625 research papers including 14 reviews in international journals/monographs/books of repute. He is credited of having coined the term colloidal plasma for a special type of plasma. In addition, he has published 30 articles on different aspects of higher education.
The honor of Padmashri was conferred on Prof Sodha by President of India in 2003. He has been Chief Guest at the Convocation ceremonies of Agra University and Kanpur University, India.
As a visionary, he has been extremely quick in identifying/realizing the importance of an emerging field and would either pursue the same or motivate a close and younger colleague to pursue the same. That is how research on guided wave optics for optical communication and Biophotonics had begun at IIT Delhi almost from its nascent days in early to mid-1970s. He was quick to realize the importance of introducing research in non-conventional energy when the oil crisis began in 1973 and took significant initiative for the establishment of the Center of Energy Studies at IIT Delhi in 1976 as a national center.
