CV

I am a 5th year PhD candidate in the mathematics department at Emory University, in Atlanta.

My advisors are David Zureick-Brown and John Voight.

My research interests lie broadly in number theory and arithmetic geometry.

Here are my arXiv papers, MathSciNet profile, and GitHub profile.

Activities

• I am in the postdoc job market!
• I am organizing Emory's algebra and number theory seminar.
• Upcoming invited talks:
  • UCSD, Number Theory Seminar. (02/12/2025)

In preparation

• Generalized Fermat equations and stacky curves,
  my PhD thesis.

Teaching and Mentoring

• Instructor of record for Math 111: Calculus 1, at Emory University. (Fall 2022 and 2023)
  • Here is a sample test (with my solution) that I helped design.
  • Here is a sample of the personal notes I wrote to prepare for my lectures. I shared these with my students as well.
• I was a Study Group Leader at the Arizona Winter School 2024.
• I was a Problem Set Leader at the Preliminary Arizona Winter School course on Abelian varieties over finite fields.
  • Here are the problem sets I helped create: PSET0, PSET1, PSET2, PSET3, PSET4, PSET4, PSET5, PSET6
• TWOPLES directed reading program.
  • Fall 2023: I mentored Sergio Maciel. We read about sheaf cohomology, mainly following Vakil's book and Hartshorne.
  • Fall 2020: I mentored Leonardo Méndez and Camilo Martinez. We read about algebraic number theory, following Milne's notes.
• Here is a note that LATHISMS wrote about me for Hispanic Heritage Month.
