My background is in Mathematics with focus on some geometrical and computational aspects. My interests lie within all sorts of numerical methods and discretization techniques for Scientific Computing. In my undergraduate and Master's studies at the University of Siena, Italy, I was fascinated by Computational Geometry and Computer-Aided Geometric Design techniques with applications in Animation and Computer Graphics. Subsequently, I obtained my PhD in Applied Mathematics at the New Jersey Institute of Technology in May 2018 with a dissertation in Computational Fluid Dynamics, in which I conducted numerical simulations of the dynamics of viscoelastic fluids. I am currently a PostDoctoral Research Associate at the University of Colorado at Boulder, under the supervision of Jed Brown developing an efficient, extensible, portable mathematical library (libCEED), within the Center for Efficient Exascale Discretization (CEED) of the Exascale Computing Project (ECP): a collaborative effort of the Office of Science (OOS) and the National Nuclear Security Administration (NNSA) of the Department of Energy (DOE).
