Hubert Girault (born 13 February 1957 in Saint-Maur-des-Fossés, France) is a Swiss chemist and is Emeritus Professor at the École Polytechnique Fédérale de Lausanne (1992-2022).

He was the director of the Laboratoire d'Electrochimie Physique et Analytique, with expertise in electrochemistry at soft interfaces, Lab-on-a-Chip techniques, bio-analytical chemistry and mass-spectrometry, artificial water splitting, CO2 reduction, and redox flow batteries.

Three years after that, in 1982, he completed his PhD thesis, entitled "Interfacial studies using drop image-processing techniques",[1] at the University of Southampton, England.

In 1992, he became a professor of physical chemistry at the École Polytechnique Fédérale de Lausanne (EPFL), where he continues to teach today.

[2] He has served twice as chairman of the Department of Chemistry, now called Institute of Chemical and Engineering Science (ISIC) for the periods 1995-1997 and 2004–2008.

[3] During the period 2011–2014, he was Dean of Bachelor & Master Studies at EPFL and has supervised a comprehensive teaching reform, with the definition of new curricula starting September 2013.

As Dean, he introduced measures to improve the quality control of education,[4] in particular by setting up, for each section, an academic commission responsible for auditing yearly all the programs.

30 former PhDs and post-docs are now professors in Canada, China, Denmark, Finland, France, Ireland, Italy, Japan, Korea, Singapore, UK & USA.

Education has been a major part of his activities, and his lecture notes have formed the basis of a textbook entitled: "Electrochimie Physique et Analytique" (now in the third edition); translated in English "Analytical and Physical Electrochemistry".
