I am currently postdoctoral researcher in the Multiscale Mechanics and Materials Modeling Lab (p.i. Prof. Seunghwa Ryu) at KAIST.

I earned a PhD in Solid and Structural Mechanics from the University of Trento in 2017 under the guidance of Prof. Nicola Pugno, director of the Laboratory of Bio-Inspired and Graphene Nanomechanics. Previously, I received a MSc in Structural Engineering from Politecnico di Torino and the Diploma from Alta Scuola Politecnica in 2013, and a 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.
