Renata Kallosh

Renata Ernestovna Kallosh (Russian: Рената Эрнестовна Каллош; born 1943) is a theoretical physicist. She is a professor at the Department of Physics of Stanford University.
Kallosh is best known for her contributions to the theory of supergravity---the supersymmetric generalization of Einstein's theory of gravity. She was the first to quantize supergravity, obtaining the full set of Feynman rules including a new, unexpected ghost particle (now called the Nielsen-Kallosh ghost). This paper also gave one of the first applications of BRST symmetry to express the gauge invariances of gravity, and, incidentally, introduced the name "BRST". She also was the first to understand the structure of divergences in quantum theories of supergravity, showing, among other results, that supergravity with N=8 supersymmetry is finite at least up to 8 loops. She is the author of many papers on black hole solutions in supergravity theories. A particularly influential work is the recognition, in collaboration with Sergio Ferrara, that black hole solutions with higher supersymmetry correspond to attractor solutions of analogue mechanical systems.
Kallosh is also known for her contributions to string theory, in particular finding (along with Sandip Trivedi, Andrei Linde, and Shamit Kachru) the first models of accelerated expansion of the universe in low energy supersymmetric string theory, referred to as "KKLT" models after the authors' last names.

Renata Kallosh completed her Bachelor's from Moscow State University in 1966 and obtained her Ph.D. from Lebedev Physical Institute, Moscow in 1968. She was then a professor at the same institute, before moving to CERN for a year in 1989. Kallosh joined Stanford in 1990 and continues to work there (as of 2014).

Professor Kallosh is married to Andrei Linde. They have two sons.
