Jorge Pullin

from Wikipedia, the free encyclopedia

Jorge A. Pullin (born February 26, 1963 in Buenos Aires ) is an Argentine theoretical physicist who deals with quantum gravity .

Pullin studied electrical engineering at the University of Buenos Aires and physics at the Instituto Balseiro of the Cuyo University in Bariloche with a master's degree in 1986 and a doctorate in 1988 with Reinaldo J. Gleiser. He was a post-doctoral student at Syracuse University and the University of Utah (1991). From 1993 he was Assistant Professor, 1997 Associate Professor and 2000 Professor at Pennsylvania State University . He has been the Hearne Professor of Theoretical Physics at Louisiana State University and Co-Director of the Hearne Institute of Theoretical Physics since 2001 .

Pullin is one of the pioneers of loop quantum gravity and has worked in this area since 1990 with the Uruguayan physicist Rodolfo Gambini . For example, they discovered connections with knot theory and showed that the Jones polynomial is the solution of the quantized Einstein equations in loop quantum gravity.

With Gambini he predicted non-classical forms of light propagation from loop quantum gravity.

He also deals with numerical general relativity, for example in the calculation of collisions between black holes, for which he uses supercomputers. He published his first work on this in the 1990s (introduction of the close approximation , in which two very closely spaced black holes are viewed as one deformed black hole).

He was a Sloan Research Fellow in 1995, a Guggenheim Fellow in 1999 and a Fulbright Fellow in 2001. He is a Fellow of the American Physical Society and the American Association for the Advancement of Science . He is also a member of the National Academies of Science of Uruguay, Mexico, Argentina and the Latin American Academy of Science. In 1995 he received a Career Award from the National Science Foundation and in 2001 the Edward Bouchet Award from the APS.

He is married to Gabriela González , who is also a gravitational physicist at the LIGO collaboration.
