Paul Joseph Steinhardt (born December 25, 1952 in Washington, DC ) is an American theoretical physicist .

Steinhardt studied at the California Institute of Technology ( Bachelor 1974), obtained his master’s degree from Harvard in 1975 and did his doctorate there in 1978 with Sidney Coleman . He was then a Junior Fellow at Harvard until 1981. He conducted research at Harvard and, from 1981, at the University of Pennsylvania , where he received a professorship in 1989. He has been a professor at Princeton University since 1998 , where he has been Albert Einstein Professor since 2001.

Steinhardt is known for his work in theoretical cosmology , where he was instrumental in the development of the theories of cosmic inflation (the so-called new inflationary model , together with his doctoral student Andreas Albrecht 1982) and Quintessenz (1998). He also worked on the methodological foundations to elucidate the properties of cosmological models through astronomical observations.

His latest work dealt with brane cosmology , especially with the ekpyrotic universe and cyclic world models (with Neil Turok ), as an alternative to inflationary models. According to his own statement, he is disappointed with the direction that the inflation theory had taken in the meantime with the emphasis on the existence of multiverses and considers this to be a dead end. Steinhardt also works on quasicrystals , for which he also holds several patents.

Steinhardt was an Alfred P. Sloan Research Fellow from 1982 to 1986 and a Guggenheim Fellow in 1994/5 . In 1986 he became a Fellow of the American Physical Society and in 1998 a member of the National Academy of Sciences . In 2002 he received the Dirac Medal (ICTP) . In 2010 he received the Oliver E. Buckley Condensed Matter Prize with Dov Levine and Alan Mackay for his work on quasicrystals.
