DESCRIPTION:Speaker: Beatrice Ferrari\nhosted by Charles Roques-Carmes\nAbs
 tract: You can also attend the talk via Zoom (https://istaustria.zoom.us/j
 /65059499044?pwd=d2ogSLRMdYzA5mb6Z8miUbcrysITpz.1). In this seminar\, I w
 ill share my journey in femtosecond-time-resolved electron microscopy\, be
 ginning with the development of a custom ultrafast TEM as the first PhD st
 udent in Prof. Vanacore's group at UniMiB (Milan). This project integrated
  a photonic-based electron modulator\, enabling pre-sample electron beam s
 haping using light. Shaped electron beams could open up new possibilities 
 for ultrafast TEMs: they could be used to selectively probe low-frequency 
 excitations in materials\, to enable low-dose imaging of sensitive scatter
 ers\, to enhance image resolution and to increase contrast.  Currently\, 
 I am doing part of my PhD at EPFL (Lausanne)\, in a more standard ultrafas
 t TEM laboratory. Here\, my focus is on studying the phononic response to 
 optical excitation of charge carriers in quasicrystalline\, 30° twisted b
 ilayer graphene. Using time-resolved electron energy-loss spectroscopy\, w
 e investigate changes in the electronic response of the material which rev
 eal the phonon dynamics.  As I am considering the possibility of joining 
 ISTA as a postdoctoral researcher\, the purpose of this seminar is not onl
 y to share my work but also to introduce myself to your community. Expect 
 a mix of science and personal anecdotes as I share the challenges and triu
 mphs of navigating the frontiers of ultrafast science. I am looking forwar
 d to meet you and I hope this talk sparks engaging discussions.  Useful

 -Bicocca with a degree in Solid State Physics. For her master’s thesis\,
  she joined Giordano Scappucci’s group at TU Delft\, where she conducted
  magnetotransport characterization of a germanium double-quantum well fiel
 d-effect transistor.Currently a PhD student in Prof. Gianmaria Vanacore’
 s group at the University of Milano-Bicocca\, Beatrice has been instrument
 al in establishing his femtosecond time-resolved transmission electron mic
 roscopy (TEM) laboratory\, also known as ultrafast TEM (UTEM). As part of 
 her doctoral studies\, she is currently working at EPFL in Prof. Fabrizio 
 Carbone’s UTEM laboratory in Lausanne.In science and beyond\, Beatrice i
 s passionate about bringing people together to climb mountains and tackle 
 challenges that would be scary alone.
