Since January 2022 I am an assistant professor (UD) in the Department of Applied Mathematics of UT within the group Mathematics of Imaging and AI (MIA).

My main research interests are in analytic (mostly variational) methods for inverse problems in imaging, shape analysis and machine learning. The approaches I am involved in tend to have a geometric flavor, either in the domain of definition of the functions involved or in the convex geometry arising from the minimization problems.

After studying for MSc degrees in both pure mathematics and telecommunication engineering in Madrid, I obtained my doctoral degree in mathematics in the University of Vienna in 2015. While working as a postdoctoral research scientist in the Radon Institute for Computational and Applied Mathematics in Linz, I received a habilitation degree (also from the University of Vienna) in 2021 with a thesis entitled "Applications of geometric variational problems to shape analysis, inverse problems and viscoplastic fluids".
