A postdoctoral position is available in the Ultrafast Photochemistry
Group at the Chemistry Department of Ecole Normale Supérieure (ENS), in
the centre of Paris.
The Ultrafast Photochemistry Group is specialized in femtosecond optical
spectroscopy, in particular applied to photoactive proteins. Its main
tools are broadband fs transient absorption spectroscopy and fs
fluorescence spectroscopy. In the last few years, the group has studied
the primary photochemistry of several photoreceptor proteins [1-4] and
of photoactive proteins able to repair UV-damaged DNA [5]. The present
project, funded by the Pierre-Gilles de Gennes foundation, deals with a
new class of photoactive proteins, of interest for fluorescence
microscopy. It involves collaboration with F. Rappaport at Institut de
Biologie Physico-Chimique (IBPC; close to ENS) for time-resolved
spectroscopy measurements in the nanosecond time-scale and longer.
The contract will be signed for a period of 18 months, with flexible
starting date from January 2013. Net salary: 2485 euros/months.
Candidates should hold a PhD in biophysics, physical chemistry or
physics and have a solid experience in time-resolved spectroscopy and/or
in the spectroscopy of proteins.
To apply, please send a detailed resume including list of publications,
the names of at least two referees and a brief motivation letter to
Agathe Espagne ([log in to unmask]).
