He is currently Director of Exceptional Class Research at the French National Centre for Scientific Research (CNRS). His primary areas of study include statistical physics, non-equilibrium thermodynamics, and complex systems. Kurchan's research often explores topics such as glassy dynamics, stochastic processes, and the behavior of disordered systems, focusing on understanding the fundamental principles underlying the statistical mechanics of complex and out-of-equilibrium systems.<ref>{{Cite web |title=Simons Collaboration on Cracking the Glass Problem |url=https://scglass.uchicago.edu/our-team/ |language=en-US}}</ref><ref>{{Cite web |date=2019-06-24 |title=El Invitado de RFI - Jorge Kurchan un físico en la Noche de la Filosofía de Buenos Aires |url=https://www.rfi.fr/es/cultura/20190624-jorge-kurchan-un-fisico-en-la-noche-de-la-filosofia-de-buenos-aires |website=RFI}}</ref><ref name=":2">{{Cite web |last=Kurchan |first=Jorge |date=December 24, 2012 |title=J.

== Education and career == Kurchan was born in Buenos Aires, Argentina. He completed his master's degree in 1985 and his Ph.D. in 1989, both in physics at the University of Buenos Aires under Daniel R. Bes. He conducted postdoctoral research at the Weizmann Institute of Science in 1990<ref>{{Cite web |title=Group Members {{!}} Prof. Eytan Domany |url=https://www.weizmann.ac.il/complex/compphys/group-members |website=www.weizmann.ac.il |language=en}}</ref> in the group of Eytan Domany and at the Sapienza University of Rome from 1991 to 1994. Kurchan joined École normale supérieure de Lyon as an associate researcher. In 1996, he became a CNRS research director at ESPCI ParisTech's physics and mechanics lab. He served as Deputy Director of the Henri Poincaré Institute from 2010 to 2013 and as Director of the Statistical Physics Laboratory at École normale supérieure in Paris from 2014 to 2018. Kurchan co-edited Europhysics Letters from 2002 to 2005 and currently edits Journal of Statistical Physics (2003–2014, 2018–present) and SciPost (2018–present).<ref name=":2" />
