Helene Bouchiat (born 1958) is a French condensed matter physicist specializing in mesoscopic physics and nanoscience. She is a director of research in the French National Centre for Scientific Research (CNRS), associated with the Laboratoire de Physique des Solides at Paris-Sud University. Topics in her research include supercurrents, persistent currents, graphene, carbon nanotubes, and bismuth-based topological insulators.
Bouchiat is the daughter of physicists Marie-Anne Bouchiat and Claude Bouchiat, and was a student at the Ecole normale superieure. Her 1986 doctoral dissertation, Transition verre de spin : comportement critique et bruit magnetique, was supervised by Philippe Monod [fr] at Paris-Sud University. With the exception of an 18-month postdoctoral research visit at Bell Labs, she has spent her entire career with the CNRS.
Bouchiat is a member of the French Academy of Sciences, elected in 2010. The academy also gave her their Anatole and Suzanne Abragam Prize in 1994, and their Jaffe Prize [fr] in 1998. She won the CNRS bronze and silver medals in 1987 and 2007 respectively.
