The information published in this page are entirely managed by PATRICK KEVIN O'KEEFFE who is completely responsible for it.

After extended periods (total 10 years) of postdoctoral work at the University of Oxford, the CNRS (French National Research Council) in Paris and the University "La Sapienza" in Rome, he joined the National Research Council of Italy as a permanent researcher in 2009. Much of his research interests in the above years were concentrated on charged particle gas phase spectroscopy making use of advanced detection systems together with optical lasers, synchrotron radiation and free electron lasers, to study the dynamics of atoms, molecules and clusters subsequent to photoexcitation. During these years he has worked at large scale photon facilities throughout Europe and the US. More recently, he has changed his principal research interests to optical femtosecond pump-probe spectroscopy and manipulation of nanomaterials in solution and the study of their interactions with molecules, nanowires, surfaces etc. He has been a recipient of both a Marie Curie Individual Fellowship and Marie Curie Reintegration Grant and has been unit leader in national projects assigned by the Italian Ministry for Research.
