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

I earned a PhD in Solid and Structural Mechanics from the University of Trento in 2017 working in the 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 KAIST. Previously, I received in 2013 the MSc in Structural Engineering from Politecnico di Torino and the Diploma from Alta Scuola Politecnica, and the BSc in Civil Engineering from Politecnico di Torino in 2010. More info here.

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