'''Daya Shankar Kulshreshtha''' (born December, 1951) is an Indian theoretical physicist, specializing in formal aspects of [[quantum field theory]], [[string theory]] and [[general relativity]].Dirac's instant-form and [[light-front quantization]] of field theories and [[D-brane]] actions, [[boson stars]], [[black holes]] and [[wormholes]] in [[general relativity]].<br />
<br />
==Education and career==<br />
Kulshreshtha obtained B.Sc. (1969) and M.Sc. (1971) degrees from [[Jiwaji University]], Gwalior. He received his Ph.D. in 1979 from the [[University of Delhi]], under the supervision of R. P. Saxena. Following an appointment as lecturer in physics at [[Rajdhani College]] of the University of Delhi in 1977, Kulshreshtha worked as a postdoctoral researcher at the [[University of Kaiserslautern]] (1982–1984). He then held a five-year position of a UGC-Research Scientist of the University Grants Commission of India at the University of Delhi (1986–1991) followed by a five year position at the University of Kaiserslautern, Germany (1990–1994) before being appointed a professor at the University of Delhi in 1994. Kulshreshtha remained a professor at the University of Delhi until 2016, serving as Head of the Department of Physics and Astrophysics during 2007–2010.<ref> Profile at [[University of Delhi]] [http://www.du.ac.in/du/uploads/departments/faculty_members/Physics_Astrophysics/2884.pdf]</ref> Since 2011 he was several times visiting faculty in the Nuclear Physics Theory Group at [[Iowa State University]] and at Carl von Ossietzky [[University of Oldenburg]].<br />
<br />
==Research==<br />
Kulshreshtha's research focuses on formal aspects of [[quantum field theory]], [[string theory]] and [[general relativity]]. In particular, he studies the canonical structure, constrained dynamics and instant-form and [[light-front quantization]] of field theory, [[string theory]] and [[D-brane]] actions using the Hamiltonian and [[path integral formulation]] as well as the [[BRST quantization]].<ref name="inspirehep.net">{{cite web|url=http://inspirehep.net/author/profile/D.S.Kulshreshtha.1|title=Shankar Kulshreshtha, Daya - Profile - INSPIRE-HEP|website=inspirehep.net}}</ref> He is a member of the International Light Cone Advisory Committee.<ref>[http://www.ilcacinc.org/ International Light Cone Advisory Committee]</ref> He helped organize the 2012 International Conference on Light-Cone Physics<ref>{{cite web|url=http://www.sciencedirect.com/journal/nuclear-physics-b-proceedings-supplements/vol/251/suppl/C|title=ScienceDirect|website=www.sciencedirect.com}}</ref> at the [[University of Delhi]].<ref>[https://sites.google.com/site/lcconference2012delhi/ 2012 International Conference on Light-Cone Physics]</ref> He also studies [[boson stars]], boson shells, [[black holes]] and [[wormholes]] in [[general relativity]],<ref name="inspirehep.net"/> work which was profiled by the [[American Physical Society]]'s ''PhysicsCentral'' site.<ref>[http://physicsbuzz.physicscentral.com/2016/05/new-study-shows-rich-physics-in-models.html Physics Buzz Blog: New Study Shows Rich Physics in Models of Hypothetical Boson Stars]</ref><ref>{{cite web|url=http://physicsbuzz.physicscentral.com/2018/05/research-revisited-knotted-hearts-boson.html|title=Research Revisited: Knotted Hearts, Boson Stars, and Magnetic Particles}}</ref><br />
