My research activity has been mainly devoted to the analysis and construction of numerical methods and mathematical models for partial differential equations of hyperbolic and kinetic type. These problems have been addressed using different methodologies in various fields of applied sciences, ranging from classical physics and engineering (gas dynamics, semiconductor, plasma physics, granular materials, quantum mechanics) to socio-economic and life sciences (traffic flow, opinion formation, wealth distribution, finance, epidemiology). Recently, my interests have focused on problems of uncertainty quantification, optimal control and machine learning.
