Category: Research Experiences

Adding here various experiences that I gained during my research work.

My Contribution to Nuclear Fusion Technology

For nearly four decades, I have been involved in the Nuclear Fusion work due to a midnight patriotic feeling while on my way out of the country for higher studies and since then have continued to play a role in developing or promoting nuclear fusion in India. I hope to continue contributing to this and expect to see applications happening in India too!

Starting in 1983 at Lawrence Berkeley Laboratory (and Univ of California, Berkeley) till 2002, I did full-time research in the area of Nuclear Fusion in USA and India. I contributed through modeling, development of data acquisition and control system, variety of system development, experiments, and operational improvements as well as solving technical problems to enhance the performance of both the first generation Tokamaks(a type of Nuclear Fusion Reactor) in Saha Institute of Nuclear Physics(SINP), Kolkata and Institute for Plasma Research(IPR), Gandhinagar to international levels of performance. At IPR, I was project leader of Aditya Tokamak from 1996 to 2002. I was also Project Leader of SST-1(Superconducting Tokamak) Operation and Control Group from 1997-2002.

Here I describe my contribution during the continued contribution to Nuclear Fusion for almost 4 decades.

How Did I Start Working in the Disability Sector

My chance entry to the disability sector through a student project changed my life for better and made me a better human being as I learned to be more positive and to “Count the ability and not the disability”

Getting Initiated

In DA-IICT, we had introduced design thinking in the second semester of BTech(ICT) program. This was followed by an internship in summer(later changed to winter) in a rural area and a Zero Credit Design project in the second year. Idea was to let them explore some area of societal benefit for a full year without any pressure of grades and timeline.


Two students, Pallavi and Ramya(both from Hyderabad) approached me(most likely in 2007) to work with me on design project with an interest in helping persons with visual impairment. They visited Blind People’s Association in Ahmedabad to get an idea of various needs. Later in summer vacation, they came across news about a girl, Bhawana from Chennai, who had passed class 10th. Normally this does not make news but Bhawana was not in a position to move or talk. She did not have fine finger movement just a coarse movement of hands. In spite of these conditions, her passing of 10th was worthy of news. Pallavi and Ramya visited her in Chennai to understand how she studies and carries out other functions.

Nuclear Fusion in India : Past, Present and Future

This is video of a plenary talk that was given at Bihar Science Conference on Dec 3, 2020 held online. Talk gives overall progress of nuclear fusion in last 4 decades in India and where we need to go. The talk also makes historic announcement regarding a privately funded Nuclear Fusion project in India code named – Project Sanlayan. Here is the link to video – talk starts after 3:00 minutes.

DYPIU : National Science Day discussion on Nuclear Fusion

Prof Prabhat Ranjan, Vice Chancellor, D Y Patil International University, Akurdi, Pune leads a discussion on use of Nuclear Fusion for a clean energy for world. This was organized on the occasion of National Science Day (Feb 28, 2021). He is joined by Dr Akash Singh, Inventor and Investor and Mr Paul Mahal, a semiconductor expert and CEO, Stanford Ventures – both based out of Silicon Valley, USA.

Remembering Charu Khandal

This is story of Charu Khandal, Lead Animator of Shahrukh Khan’s movie Ra-One, who met with a terrible accident. I tried to help her through assistive technology and as she was about to get back to Bollywood, we lost her!

Facebook memory showed up a post of mine from Jan 17, 2017 where I had shared a sad news about shocking demise of Charu Khandal – Ra-One movie animator. I felt compelled to narrate her story as I know it.

Dancing Sparks in ADITYA Tokamak(Nuclear Fusion Reactor)

This blog talks about how we started to notice sparks at different location on the top of machine, which had nothing to do with insulation failures but improper grounding and kept us clueless for long time.

Sudden Silence in ADITYA Tokamak(Nuclear Fusion Reactor)

This blog is about an accident on Dec 1, 1999, when two of the ADITYA’s magnet coils broke apart from their support system and got thrown out. Important lessons can be learnt from this incident.
