Short bio

Michele completed his master degree at the University of Parma (Italy) in 2011 and received his Ph.D. degree in Physics from the University of Basel (Switzerland) in 2015. During his doctorate he focused on studying the effect of electric fields and ultrashort laser pulses in magnetic materials and multiferroics using soft x-ray spectroscopies both at synchrotrons (Swiss Light Source (CH), Diamond (UK), BESSY (DE)) and at the free electron laser FLASH in Hamburg. He joined Andrea's group in 2016.

Michele’s research interests involve the control of quantum materials using intense THz and mid-infrared pulses. He is particularly interested in organic materials, where excitation of local molecular vibrations can modify the electronic interaction parameters to reveal dynamical states not accessible at equilibrium. To this end, he uses different time-resolved spectroscopies to track the changes in materials’ properties induced upon photoexcitation.
