Analysis, partial differential equations, differential geometry. More specifically, I am interested in the mathematical analysis of differential equations with a geometric background, like the Einstein equations in the context of the classical theory of general relativity. One of my main goals is to understand the nature of singularities that are typically found in the interior of black holes or at the Big Bang.
This Fall (2022) I am teaching a basic course of ODEs.
I am an organizer of the Joint online Mathematical Relativity Colloquium (JoMaReC). To receive notifications for upcoming colloquia, you are invited to subscribe to our newsletter.
Seminar of Differential Equations and Numerical Analysis at the Department of Mathematics & Applied Mathematics. If you wish to give a talk, please send me an email.

Πᾶσά τε ἐπιστήμη χωριζομένη δικαιοσύνης καὶ τῆς ἄλλης ἀρετῆς πανουργία, οὐ σοφία φαίνεται. (Πλάτωνος Μενέξενος)
All knowledge cut off from rectitude and the rest of virtue has the look of low cunning, not wisdom. (Plato's Menexenus)
