Paul Steinhardt

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), made in 1975 in Harvard his master's degree and his doctorate there in 1978. Afterwards it was until 1981 a Junior Fellow at Harvard. He conducted research at Harvard and from 1981 at the University of Pennsylvania, where he received a professorship in 1989. Since 1998 he is a professor at Princeton University, where he is the Albert Einstein Professor since 2001.

Steinhardt is known for his work in theoretical cosmology, where he was instrumental in the development of theories of cosmic inflation ( the so-called new inflationary model, together with his PhD student Andreas Albrecht 1982) and quintessence was involved. He also worked on the methodological foundations of cosmological models can explain by astronomical observations properties.

His most recent work dealt with the Branenkosmologie, especially with the ekpyrotischen universe and cyclical world models ( with Neil Turok ). Furthermore Steinhardt working on quasicrystals, for which he also holds several patents.

Steinhardt was 1982-1986 Alfred P. Sloan Fellow and 1994/5 Guggenheim Fellow. In 2002 he was awarded the Dirac Medal ( ICTP ). In 2010 he received with Dov Levine and Alan Mackay Oliver E. Buckley Condensed Matter Prize for his work on quasicrystals.
