Agathe Espagne

Agathe Espagne is a CNRS Research Fellow and Lecturer at the École normale supérieure (ENS), PSL University, Paris. Her research focuses on photochemical mechanisms in light-sensitive proteins and molecules, including cis/trans photoisomerization, photoinduced electron and proton transfer, and fluorescent proteins (photophysics, photochemistry, engineering, and applications). She employs time-resolved spectroscopy (transient absorption, time-resolved fluorescence) across femtosecond to millisecond timescales.

• Education: PhD in Physical Chemistry (2005), École normale supérieure (ENS), Paris
• Postdoctoral Training: Caltech (femtosecond fluorescence), MBI Berlin (femtosecond IR)

Her work spans fluorescent protein engineering, photophysics, and ultrafast spectroscopic analysis to explore protein dynamics, light-induced reactions, and imaging applications. Recent studies highlight trends in photoswitchable proteins, dynamic contrast imaging, and gold-catalyzed photochemical reactions.

Agathe Espagne collaborates with interdisciplinary teams at institutions like CEA-Saclay, LCP Orsay, and ENS, advancing time-resolved spectroscopy and fluorescence imaging techniques. Her research contributes to understanding photoactive protein mechanisms and optimizing fluorescent probes for biomedical applications.
