Ashoke Sen, FRS (/
|Residence||Allahabad, Uttar Pradesh, India|
|Known for||Contributions to string field theory|
After completing his schooling from Scottish Church Collegiate School and Sailendra Sircar Vidyalaya 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 recent important works include the attractor mechanism and the precision counting of microstates of black holes, and new developments in string perturbation theory. He joined the National Institute of Science Education and Research (NISER), Bhubaneswar, India as an honorary fellow.
