Jacques-Edouard Moser directed the Group for Photochemical Dynamics (Moser Group) of EPFL until his retirement in 2023.
He is a graduate of the École polytechnique fédérale de Lausanne (EPFL), where he received a diploma degree (MSc) in chemical engineering in 1982. After two stays in 1984 and 1985 at Concordia University in Montréal (Canada), he earned in 1986 his Ph.D. in physical chemistry at EPFL (Michael Grätzel, thesis advisor).
In 1986, he joined the Eastman Kodak Corporate Research Laboratories at Rochester (NY, USA) as a postdoctoral fellow and was later associated with the NSF Center for Photoinduced Electron Transfer at the University of Rochester. Returning to Switzerland, he was appointed as a lecturer of physical chemistry at EPFL in 1992 and was awarded the habilitation and the venia legendi in 1998. He is titular professor since 2005.
His research activity focused on the study of the dynamics of photoinduced electron transfer and charge carrier separation at donor-acceptor heterojunctions and in nanostructured semiconductors. He is the author and co-author of more than 250 scientific papers (h-index 84). He taught general physical chemistry to freshmen students in chemistry. He gave two classes on general- and redox photochemistry in the MSc program in chemistry and chemical engineering and the doctoral programs in energy and photonics. He still teaches Photochemistry I at the Master level.
Jacques-E. Moser presided the Swiss Society of Photochemistry and Photophysics (1995-1998) and chaired the jury of the Grammaticakis-Neumann international prize in photochemistry (1999-2001). He was a member of the board of the Swiss Chemical Society (2007-2012). He served as a member of the standing committee of the European Photochemistry Association (1992-2000) and of the executive committee of the division for fundamental research of the Swiss Chemical Society (1999-2014). He was the director of the Section of Chemistry and Chemical Engineering of EPFL and a member of the direction of the School of Basic Sciences from 2007 to 2015.

The research of the Moser Group concentrated on the preparation and characterization of donor-acceptor heterojunction photovoltaic systems and aimed at the understanding of the mechanisms and dynamics of light-induced and relaxation processes at the basis of their functioning.
Systems under investigation encompassed dye-sensitized nanodispersed metal oxides, lead halide perovskite nanoparticles and thin films of various composition and dimensionality, and small molecules-based organic semiconductors.
Ultrafast time-resolved techniques were mainly used to scrutinize the dynamics of fundamental phenomena, which prevail in nanostructured materials and at their interfaces. Identification of reaction intermediates and quantification of the kinetics of the numerous steps involved in photoinduced charge separation were achieved by a combination of ultrafast transient absorption, fluorescence up-conversion, and time-resolved THz spectroscopies.
Specific investigation methods, such as ultrafast diffuse reflectance, time-resolved electroabsorption, ultra-broadband THz, and optical pump/IR push/THz probe spectroscopies have been developed in our lab to address important scientific questions related to photonic materials and systems close to working conditions..
