About me

I am a postdoc at Leiden University in the Mathematical Institute. I obtained my PhD in May 2021 from the University of Pennsylvania under the supervision of Antonella Grassi.

Before that I completed B.Sc. and M.Sc. degrees in Mathematics at the Federal University of Paraná (UFPR) in Brazil.

You can find a copy of my CV here (last updated August 2021).

Ouro Preto, Brazil - January 2020

Research interests

My research interests lie at the interface of Birational Geometry and Moduli Theory. I am also generally interested in algebraic and topological invariants of singularities.

A unifying theme in my research has been the study of the geometry of genus one fibrations, mostly in dimensions two and three.

  • American Graduate Student Algebraic Geometry Seminar (AGSAGS) – Fall 2020 and Spring 2021

In response to the Covid 19 pandemic I was a co-organizer of AGSAGS together with Jennifer Li, Lena Ji, Roberto Albesiano and Samir Canning.

AGSAGS was a virtual seminar by and for algebraic geometry graduate students. Our goal was for graduate students to share their research through online talks and to provide an algebraic geometry graduate networking system.

  • Very Short Talks – Fall 2020 and Spring 2021

With Artur B. Saturnino, I co-organized a series of (virtual) short talk events in the Math department at Penn. We invited grad students, postdocs and faculty to give a brief introduction about themselves and their research interests.

  • Directed Reading Program (DRP) – Spring 2020

I was a mentor in the DRP chapter at Penn . My mentee was Scott le Roux and together we learned about how Topology can be used in the study of some computational problems.

  • woMAN UP! – Fall 2019

I participated on a panel about grad student life on the workshop woMan UP!. This was an event aimed at undergraduate women who were applying to math graduate school.

  • Toric Geometry Reading Seminar – Fall 2018

I organized a reading seminar on Toric Geometry for graduate students both in the Math and in the Physics departments.

We covered Part I of Cox’s book.

  • TA training

For three consecutive years I was one of the master TAs in the Math department at Penn. My duties included helping to organize and to conduct the annual TA training aimed at first time TAs. And also carrying out in-class observations of the new TAs followed by informal meetings.
