ÖZLEM SEL – CNRS RESEARCHER CRCN-HDR

Ozlem Sel joined the « Centre national de la recherche scientifique (CNRS) » as a principal investigator in 2011 and is currently working at the « Solid-State Chemistry and Energy Lab (CSE) » at Collège de France, Paris. Her research interests include the use of piezoelectric sensors in conjunction with electrochemical analysis for real-time monitoring of the interfacial processes occurring in energy storage devices.

She obtained her Ph.D. degree in materials chemistry at the Max Planck Institute of Colloids and Interfaces in Germany in 2007. Her Ph.D. research focused on the synthesis, characterization, and applications of hierarchically porous metal oxides under the supervision of Prof. Markus Antonietti. Following her Ph.D., she moved to France and joined the group of Prof. Clement Sanchez (LCMCP, Sorbonne University-UPMC) as a post-doctoral researcher from 2007 to 2009. During this time, she concentrated on nanostructured hybrid materials and their characterization for energy conversion devices.

In the period from 2010 to 2011, she conducted research at UC-Davis in the group of Prof. Alexandra Navrotsky in the USA within the framework of the Energy Frontier Research Centers (EFRCs) program. Prior to joining the CSE lab at Collège de France, she worked as a principal investigator at the « Laboratory of Interfaces and Electrochemical Systems, CNRS-UMR8235 » and obtained her research habilitation at Sorbonne University, Paris.

Over the years, she has developed expertise in nanostructured energy materials and electrochemistry, as well as operando methods for surface and interface characterization. She is particularly interested in Electrochemical Quartz Crystal Microbalance (EQCM) and its coupling with Electrochemical Impedance Spectroscopy (EIS), with more than 15 years of active involvement in this area of research.
