Pranawachandra Deshmukh
Indian physicist, educator and administrator
From Wikipedia, the free encyclopedia
Pranawachandra Deshmukh[1][2] is an Indian physicist and educator renowned for his contributions to theoretical atomic physics, atomic collisions, light–matter interactions, ultrafast atomic processes, and applications of Lambert W Function in pure and applied physics. He has made significant contributions to physics education, including publishing foundational classical and quantum physics textbooks.[3] Throughout his teaching career, he has instructed courses in classical mechanics,[4] electrodynamics, quantum mechanics, and quantum collision physics.[5][6] Many of his lectures are freely accessible through the National Programme on Technology Enhanced Learning[6][7][4][5][8](NPTEL), Swayamprabha where they benefit students and educators across India and beyond. His research group is one of the main contributors to the relativistic many-body studies of atomic photoionization,[9][10][11][12][13] particularly the photoionization processes of free and confined atoms. His work includes studies of attosecond time delay, highlighting the role of electron correlations, relativistic effects and interchannel coupling. His broader research interests also include quantum information science and mathematical physics.[14][15][16][17]

Prof. Deshmukh has authored over 300 research publications, including approximately 150 journal articles and around 200 conference contributions. He has supervised 17 doctoral theses and over 20 master's and undergraduate theses.[1]
Prof. Deshmukh has been awarded the prestigious ANRF Prime Minister Professorship[18] in Dec 2025. Currently, he serves as a professor in the Dept. of Physics, Central University of Kerala[19] where he plans to mentor researchers and help build an advanced research eco-system. Prior to this he was the Founder-Convenor and Mentor of the Center for Atomic, Molecular, and Optical Sciences ad Technologies (CAMOST[20])[21] in Tirupati. CAMOST is a joint initiative of the Indian Institute of Technology Tirupati (IITT)[22] and the Indian Institute of Science Education and Research Tirupati (IISERT).[23] Concurrently, he is RV Chair Professor at the Centre for Quantum Science and Technology (CQST), School of Computer Science and Engineering (SoCSE)[24] at RV University, where he guides research and educational efforts in quantum science, drawing on his vast expertise to support the center's growth and innovation. Besides, he is the Chief Technology Advisor to the Vivekananda Institute of Professional Studies (VIPS), Delhi[25]
Early life and education
Deshmukh was born in Amravati, Maharashtra, on 12 September 1950. He completed his higher education in Nagpur,[26] where he studied at the Saraswathi Vidyalaya, Hadas High School, Institute of Science, and the Postgraduate Department of Physics of Nagpur University.[2] He obtained a Bachelor of Science degree in 1970 and a Master of Science (Physics)[26] in 1972. After his master's degree, he obtained a Ph.D. in physics at Nagpur University in 1979 under the supervision of Dr. C. Mande and Dr. P. L. Khare.[1]
Career and research
Following his doctoral work,[20] Deshmukh was a DANIDA fellow at the University of Aarhus in the Department of Theoretical Chemistry (1978–1979), where he worked with Professor Jan Linderberg. He then worked as a research associate at the University of Notre Dame with Professor Robert Hayes and Professor W. R. Johnson.[27] From 1980 until 1983, Deshmukh was a research associate and adjunct assistant professor at Georgia State University, collaborating with Professor S. T. Manson.[28]
In 1984, Deshmukh joined the Department of Physics at the Indian Institute of Technology Madras[1] as an assistant professor of physics, becoming a full professor in 1995, a position he held until 2016. During his tenure at IIT Madras, he was appointed on deputation as professor of physics and dean of academics at the Indian Institute of Technology Mandi (2009–2010).[2]
In 2016, Deshmukh joined the Indian Institute of Technology Tirupati as a professor of physics.[23] Simultaneously, the Indian Institute of Science Education and Research Tirupati invited him to deliver several courses and mentor its students. In 2020, Deshmukh set up CAMOST, a joint initiative of IITT and IISERT.[20]
Professor Pranawachandra Deshmukh has supervised numerous Ph.D. students:[1] Dr. N. Shanthi, Dr. R. Padma, Dr. E. W. B. Dias, Dr. Tanima Banerjee, Dr. Hari R Varma, Dr. S. Sunil Kumar, Dr. Jobin Jose, Dr. Gagan Bihari Pradhan, Dr. Manas Ranjan Parida, Dr. N. M. Murthy, Dr. K. Sindhu, Dr. A. K.
