About Me



Welcome to my webpage


Since September, 2023, I am a postdoctoral researcher at CMU (Carnegie Mellon University), mentored by prof. Robin Neumayer. I completed my Ph.D. at IME-USP under the supervision of prof. Stefano Nardulli and prof. Camillo De Lellis.

My research lies within the fields of Geometric Analysis and Geometric Measure Theory. I kindly invite you to click on the Menu to get more info about me, my research and activities.


Forthcoming travels:
  • Joint Meeting AMS-UMI, from July 23 to July 26, 2024, at Università degli Studi di Palermo, Palermo, Italy.

  • MCA 2025, from July 21 to July 25, 2025 at University of Miami, USA.

    • Hard work will always overcome natural talent when natural talent does not work hard enough!
    Theorems are corollaries of understanding.

                        • My Research

                        My main field of research is geometric measure theory (GMT). I am also interested in geometric analysis, calculus of variations, some aspects of regularity of PDEs and elliptic systems.
