Giovanni Maria Vanacore studied Physics Engineering at the Politecnico di Milano (Milano, Italy), with a major interest toward condensed matter physics, nanotechnology and lasers. During his Ph.D. in co-tutorship between the Politecnico di Milano and the École Polytechnique X (Paris, France) under the guidance of Prof. Alberto Tagliaferri, Dr. Nicholas Barrett, Prof. Henri-Jean Drouhin, he worked on the investigation of electronic and structural properties of semiconductor nanostructures using spectro-microscopy techniques. In November 2011, he joined as postdoctoral scholar the group of Prof. Ahmed H. Zewail at the California Institute of Technology (Caltech), where his research activity was focused on the investigation of ultrafast phenomena in nanomaterials by means of ultrafast electron diffraction and ultrafast electron microscopy. In February 2016, he moved to Switzerland at the École Polytechnique Fédérale de Lausanne (EPFL) in the group of Prof. Fabrizio Carbone as senior scientist, while partially supported by the EPFL Fellowship program co-founded by Marie Sklodowska-Curie. Here, he explored new methods for the coherent longitudinal and transverse phase manipulation of a free-electron wave function using light pulses with attosecond precision. Since December 2019, he is a Tenure Track Assistant Professor at the University of Milano-Bicocca where his activity is dedicated to the investigation of ultrafast phenomena in nanoscale low-dimensional materials using ultrafast electron microscopy.
