Brief Research Description

  • Calculus of Variations

    I am mainly interested in Fundamental theory of multi-marginal optimal transport (transport plans, densities, potentials, existence and regularity of transport maps); Gamma-convergence. Computational realizations of Multi-marginal Optimal Transport (MOT), Convex/Entropic regularization of MOT.


  • Computational Chemistry

    The focus of my current research is to extend the accuracy of electronic Density Functional Theory (DFT) to systems in which electronic correlation plays a prominent role. In particular using the SCE formalism in the study of ground state properties of many-electrons system (existence and next-order corrections of SCE DFT) and time-dependent DFT (1d). I am also developing Non-commutative Optimal Transport methods to One-body Reduced Density Matrix (1RDM) functional theory.

  • Mathematical and Computational Aspects of Machine Learning

    I am developing tools to improve the understanding of density estimation and generation in GANs, VAES and Normalizing Flows; and developing novel deep learning methods for Computational Chemistry.
