Dr Yoshie Murooka
"Magnetic dynamics studied by time-resolved electron microscopy"
Biography:
He received his PhD at the Cavendish Laboratory, University of Cambridge on the project to reveal electron beam induced chemical/structural dynamics under sub-nanometer probe, by developing time- and momentum-resolved EELS on a dedicated STEM.
In order to investigate much faster dynamics at nanoscale, he joined Prof. Ruan’s group at Michigan State University in 2005 to develop and apply Ultrafast-Electron-NanoCrystallography at 30keV that achieved the time resolution of ~600fs. With this technique, laser induced structural dynamics were studied for nanomaterials and nanosurfaces.
To reveal even faster dynamics, he then joined Prof. Tanimura’s group at Osaka University in 2008 to develop and apply Ultrafast-Relativistic-Electron-Diffraction using RF-photocathode, i.e. 3MeV and ~100fs. Laser induced electronic/structural dynamics were studied combined with ultrafast optical spectroscopy. Since 2013, he joined Prof. Carbone’s group at EPFL to apply Dynamics Transmission Electron Microscopy for fast dynamics in magnetic materials.
