Ashoke Sen (Bengali: অশোক সেন) (born 1956) is among India's most famous theoretical physicists. He has 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,[1] 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. One of his most recent contributions include the entropy function formalism for extremal black holes and its applications to attractors. His current research interests are centered around the attractor mechanim and the precision counting of microstates for black holes in string theory. Of his nearly 200 research papers, as many as 47 papers have over 100 citations each [1].
Sen received his PhD from Stony Brook University. During his early career, he worked as a research scientist at Fermilab and the Stanford Linear Accelerator Center (SLAC). Later he joined the Indian Tata Institute of Fundamental Research (TIFR) before finally moving to the Harish-Chandra Research Institute (HRI) where he currently works. He is married to Dr. Sumathi Rao, a condensed matter physicist at HRI.
Sen was awarded the ICTP Prize in memory of Hideki Yukawa in 1989[2] the S.S. Bhatnagar award in 1994 and the Padma Shri in 2001. In 1998 Sen was made a Fellow of the Royal Society.[3]
The Outlook magazine of April 23, 2007 has listed him amongst India's 25 people who will not make it to the power list, yet have made significant contributions to society.
