Dr ashoke sen on winning biggest jackpot in the world of science

Ashoke Sen, FRS (; Bengali: অশোক সেন; born 1956) is an Indian theoretical physicist and distinguished professor at the Harish-Chandra Research Institute, Allahabad. He also is the Morningstar Visiting professor at MIT and a distinguished professor at the Korea Institute for Advanced Study. His main area of work is String Theory. He was among the first recipients of the Fundamental Physics Prize “for opening the path to the realisation that all string theories are different limits of the same underlying theory”. Of the prizes for theoretical physics, the Fundamental Physics Prize is the one which pays the most prize money.

After completing his schooling from the Sailendra Sircar Vidyalaya and the Scottish Church Collegiate School in Kolkata, he earned his Bachelor of Science degree in 1975 from the Presidency College under the University of Calcutta, and his master’s a year later from the Indian Institute of Technology Kanpur. During his undergraduate studies at Presidency, he was greatly inspired by the work and teaching of Amal Kumar Raychaudhuri. He did his doctoral work in physics at Stony Brook University.


Ashoke Sen made a number of major original contributions to the subject of string theory, including his landmark paper on strong-weak coupling duality or S-duality, which was influential in changing the course of research in the field. He pioneered the study of unstable D-branes and made the famous Sen conjecture about open string tachyon condensation on such branes. His description of rolling tachyons has been influential in string cosmology. He has also co-authored many important papers on string field theory. In 1998 he won the fellowship of the Royal Society on being nominated by the theoretical physicist Stephen Hawking. His contributions include the entropy function formalism for extremal black holes and its applications to attractors. His current research interests are centered on the attractor mechanism and the precision counting of microstates of black holes. Recently he has joined National Institute of Science Education and Research (NISER), Bhubaneswar, India as an honorary fellow.
