My goal is to develop and apply theoretical tools to phenomena arising from real world applications.

My research interest lies in the field of Nonlinear Analysis. I focus on the study of existence, multiplicity and chaotic behaviors of solutions for boundary value problems (BVPs) associated with ordinary differential equations (ODEs) and with partial differential equations (PDEs).

I am an expert user of Mathematica and LaTeX.

Bio & CV

Currently, I am a PostDoc Researcher funded by FSMP (Fondation Sciences Mathématiques de Paris) at CNRS - CAMS (Centre d'Analyse et de Mathématique Sociales) - EHESS (École des Hautes Études en Sciences Sociales), Paris (France), supervised by Prof. Henri Berestycki.

From January 2019 till November 2019, I have been a PostDoc funded by INdAM (Istituto Nazionale di Alta Matematica) at Department of Mathematics and Geosciences, University of Trieste (Italy), supervised by Prof. Pierpaolo Omari. From July 2018 till December 2018 I have been a PostDoc at CMUP-Centre for Mathematics of the University of Porto (Portugal) under the supervision of Prof. Isabel Labouriau.

On February 2018, I got my PhD in Computer Science, Mathematics and Physics with mention Doctor Europaeus under the supervision of Prof. Fabio Zanolin at the University of Udine. During my PhD, I have got the opportunity to carry out research and training activities off-site at the "Center for Mathematics, Fundamental Applications and Operations Research" at the University of Lisbon in Portugal.

I gained teaching experience in undergraduate courses on calculus at the University of Udine in Italy.

Outside of academia, I enjoy traveling all around the globe, exploring cultures and panoramas to catch the mood. Here's a taste.
