Marie Erard got her PhD in Chemistry (major Bioelectrochemistry) as student of the Université Pierre et Marie Curie (Paris, France) in 2002. She was hired in 2003 as assistant professor at the Université Paris Sud (Orsay, France) and has been promoted professor in 2016. Marie Erard is affiliated to the BioPhysique Group of the Laboratoire de Chimie Physique (http://www.lcp.u-psud.fr/spip.php?rubrique82).
She focus her research activities on the development of physico-chemical methods to analyze biological phenomena at the single cell level mainly using micro-spectroscopic techniques (FLIM, FRET, FCCS). Her aim is to allow new insights on the spatio-temporal diversity of cellular behaviors and to offer original solutions for the detection and the quantification of complex biological phenomena. She has major contributions in the field of fluorescent proteins and their applications as genetically encoded biosensors to detect physicochemical parameters, metabolites or probe protein-protein interactions. She collaborates with cell biologists of various fields. Over the past years, she dedicated part of its activities to design imaging strategies adapted to the study of NADPH oxidase complexes, key enzymes of oxidative stress.
