Welcome to my research webpage. Here you can find information about my scientific activity, link to publications and resources I have developed, and updates on outreach activities.

I am a structural engineer working in the fields of materials science and applied physics, currently as research scientist at the Fraunhofer Institute for High-Speed Dynamics, Ernst-Mach-Institut, EMI.

I received a PhD in Solid and Structural Mechanics from the University of Trento in 2017 (Laboratory of Bio-Inspired and Graphene Nanomechanics). From 2017 to 2019 I have been postdoctoral researcher in the Multiscale Mechanics and Materials Modeling Lab at the Korea Advanced Institute of Science and Technology (KAIST). Previously, I received the MSc in Structural Engineering from Politecnico di Torino and the Diploma from Alta Scuola Politecnica in 2013, and the BSc in Civil Engineering from Politecnico di Torino in 2010.

My research focuses in understanding the fundamental mechanisms that govern the behavior of materials and structures under extreme conditions, such as hypervelocity impacts and shock, via multiscale and multiphysics computational simulations, from atomic to macro scale. I am also interested in developing computational strategies and tools towards a more efficient and accurate modeling of such phenomena.
