Biography
Frédérique Battin-Leclerc?is?a?CNRS?research?director at?LRGP?in?Nancy.?Her?studies?concern?combustion,?particularly?the?gas-phase?combustion?of?hydrocarbons including biofuels, in order to develop cleaner-burning?automotive?fuels.?She was awarded an ERC Advanced Grant in 2008, received the CNRS Silver Medal in 2010, and was appointed Knight of the "Ordre national du Mérite" in 2012. In 2012, she was appointed as a Program Co-Chair of the 34th International Symposium on Combustion, in 2018, she was elected to the inaugural class of Fellows of the Combustion Institute, and in 2022, she was honored with the Polany Medal of the Royal Society of Chemistry.
