'''Kalyan Bidhan Sinha (K.B. Sinha)''' (born 3 June 1944) is an Indian [[mathematician]]. He is a professor at the Jawaharlal Nehru Centre for Advanced Scientific Research,<ref>[http://www.jncasr.ac.in/tsu_faculty.php] JNCASR </ref> and Professor Emeritus for life of the [[Indian Statistical Institute]].

Sinha is the author of numerous scientific works<ref>[https://scholar.google.com/scholar?hl=en&as_sdt=0%2C7&q=sinha+kalyan+b&btnG=] Google Scholar</ref> in [[scattering theory]], [[spectral theory]] of [[Schrödinger operator]]s, [[quantum stochastic calculus]], [[noncommutative geometry]], and, more broadly, in [[mathematical physics]].

==Education and career==
Kalyan Bidhan Sinha graduated from [[Hindu School, Kolkata|Hindu School, Calcutta]] in 1960. He studied Physics at [[Presidency College, Calcutta]], obtaining his Bachelor's degree from the [[University of Calcutta]] in 1963, and then studied at the [[University of Delhi]] where he was awarded a Master's degree in 1965. He obtained his Ph.D. in Physics from the [[ University of Rochester]] in 1969.

Sinha was a post-doctoral research associate at the University of Geneva. During this time he co-authored, with Werner Amrein and [[Josef-Maria Jauch]], a well-known book<ref>Amrein, Werner O.; Jauch, Josef M.; Sinha, Kalyan B. Scattering theory in quantum mechanics. Physical principles and mathematical methods. Lecture Notes and Supplements in Physics, No. 16. W. A. Benjamin, Inc., Reading, Mass.-London-Amsterdam, 1977</ref> on scattering theory, which used mathematically rigorous methods to develop the subject.

Sinha served on the faculty of the [[Indian Statistical Institute]] from 1978 to 2005, serving as Director of the institute from 2000 to 2005. He has held numerous visiting faculty positions, at RIMS ([[Kyoto|Kyoto University]]),<ref>[http://www.kurims.kyoto-u.ac.jp/en/index.html/ RIMS, Tokyo]</ref> [[University of Texas, Austin]], [[University of Geneva]], among many other institutions. He was Ulam Visiting Chair Professor at the [[University of Colorado, Boulder]] in 1980. He is currently Honorary Professor, [[Jawaharlal Nehru Centre for Advanced Scientific Research]], [[Bangalore]]. He is also Distinguished Associate of Institute Mathematics Initiative, [[Indian Institute of Science]], and Professor Emeritus, [[Indian Statistical Institute]].

Sinha is President of the ''Association for Quantum Probability and Infinite Dimensional Analysis''<ref>[https://sites.google.com/site/associationqp/scientific-committee/ AQPIDA]</ref> (since 2013). He has served on numerous editorial boards, including those of ''Infinite Dimensional Analysis, Quantum Probability, and Related Topics'',<ref>[https://www.worldscientific.com/worldscinet/idaqp IDAQP]</ref> [[Reviews in Mathematical Physics]], and the ''Journal of Stochastic Analysis''.<ref>[https://digitalcommons.lsu.edu/josa/ JOSA]</ref>

==Honors==
In 2019 Sinha was awarded the Srinivasa Ramanujan Medal of the [[Indian National Science Academy]].<ref>[http://insaindia.res.in/recipients.php/Srinivasa Ramanujan Medal]</ref> He received the [[Shanti Swarup Bhatnagar Prize for Science and Technology]], the highest science award in [[India]], in the mathematical sciences category in 1988.<ref name=List>{{cite book|author1=Sukumar Mallick|author2=Saguna Dewan|author3=S C Dhawan|title=Handbook of Shanti Swarup Bhatnagar Prize Winners(1958 - 1998)|year=1999|publisher=Human Rsource Development Group, [[Council of Scientific & Industrial Research]]|location=New Delhi|pages=118|url=http://www.csirhrdg.res.in/ssb.pdf|access-date=25 June 2013|archive-url=https://web.archive.org/web/20160304043957/http://www.csirhrdg.res.in/ssb.pdf|archive-date=4 March 2016|url-status=dead}}</ref> In 2004 Sinha was awarded the P.C.
