Steven Giddings is an American theoretical physicist known for work on black hole information paradox, quantum gravity, and the interface of general relativity with quantum mechanics. He has contributed to conceptual and technical developments in string theory, Hawking radiation studies, and proposals addressing unitarity in black hole evaporation. His career spans academia, research institutes, and collaborative efforts linking communities such as Institute for Advanced Study, Perimeter Institute, and CERN.
Giddings was born in the United States and pursued undergraduate studies at Harvard University where he engaged with faculty including Sidney Coleman and exposure to seminars featuring Richard Feynman and Murray Gell-Mann. He completed graduate work at Princeton University under the supervision of John Wheeler, interacting with scholars such as Kip Thorne, Bryce DeWitt, Roger Penrose, and Stephen Hawking. His doctoral research connected to themes in quantum field theory and general relativity, and he participated in programs at Caltech, Institute for Advanced Study, and summer schools organized by Les Houches and Niels Bohr Institute.
Giddings held faculty positions at University of California, Santa Barbara and collaborated with researchers at institutions including SLAC National Accelerator Laboratory, Brookhaven National Laboratory, Lawrence Berkeley National Laboratory, and Stanford University. He taught courses relating to general relativity, quantum mechanics, and string theory, supervising students who later worked with groups at Princeton University, MIT, Harvard University, and Cambridge University. Giddings participated in conferences such as Strings Conference, GR Conference, and workshops at Perimeter Institute, KITP, CERN, and Aspen Center for Physics.
Giddings made notable contributions to the study of the black hole information paradox, proposing frameworks that interact with concepts from unitarity, entanglement entropy, and S-matrix theory. He investigated modifications to semiclassical descriptions of Hawking radiation and explored implications for AdS/CFT correspondence developed by Juan Maldacena and colleagues like Edward Witten and Gerard 't Hooft. His work on nonlocality and information retrieval drew on ideas from Don Page's analysis, Polchinski's firewall debate, and thought experiments related to Bell's theorem and Einstein–Podolsky–Rosen paradox discussed by Albert Einstein and Niels Bohr. Giddings examined black hole scattering, trans-Planckian issues raised by Jacobson and Unruh, and proposed phenomenological signatures potentially accessible to observatories such as LIGO, Event Horizon Telescope, and particle facilities like Large Hadron Collider. He engaged with mathematical structures from Calabi–Yau manifolds in string compactification dialogues with researchers like Andrew Strominger, Cumrun Vafa, and Michael Green. His proposals intersected with notions from quantum information theory developed by Peter Shor, John Preskill, and Alexei Kitaev.
Giddings' work has been recognized by invitations and fellowships at institutions including Institute for Advanced Study, Perimeter Institute, and Kavli Institute for Theoretical Physics. He has delivered named lectures at venues such as Royal Society, National Academy of Sciences, and American Physical Society meetings. His research has been cited in review articles and texts alongside contributions by Stephen Hawking, Roger Penrose, Kip Thorne, Edward Witten, and Juan Maldacena.

Giddings has participated in interdisciplinary collaborations involving scholars from philosophy of science circles, engineering groups at Caltech and MIT, and outreach with media such as Scientific American and Nature. He has served on advisory panels and refereed for journals associated with American Physical Society, Physical Review Letters, and Journal of High Energy Physics, interacting with editorial boards featuring editors from Oxford University Press and Cambridge University Press. His public lectures have connected to audiences at Royal Institution, World Science Festival, and university colloquia at Harvard University, Princeton University, and University of Cambridge.
