I am a MSc student at Regensburg, within the ALGANT program, where I am very fortunate to be working under the guidance of Prof. Radu Curticapean. I am also looking for doctoral positions in extremal combinatorics and theoretical computer science!

I am generally interested in extremal and probabilistic combinatorics, graph theory, number theory, and their applications to theoretical computer science, data science, and learning theory. For more information, see my research page. My Erdős number is 2.

I graduated from the University of Utah in Spring, 2020. I also spent an semester at the Math in Moscow program and another at the Budapest Semesters in Mathematics program, for which Department of Mathematics of the University of Utah wrote an article.

I am a contributor of the open-source mathematics software system SageMath, and in particular its algebraic geometry, dynamics, and graph theory components. I also write other software, have run two half-marathons in Shanghai in 2014 and in Hong Kong in 2016, and also have run the Chicago Marathon in 2017. When I am not studying or working, I generally enjoy reading, playing chess and Weiqi/Go, and photography.


  • August, 2023: I participated in the Copenhagen Summer of Counting & Algebraic Complexity in Denmark, thanks to the generosity of Prof. Radu Curticapean!

  • July, 2023: I participated in the Summer School in Mathematics at ELTE in Budapest. It has been a fascinating experience.

  • June, 2023: I attended the FoCM 2023 conference in Paris.

  • February, 2023: I visited Jan Volec at the Czech Technical University in Prague. Thank you for hosting me, Prof. Volec!

  • Summer, 2022: I worked on a Google Summer of Code project to improve height functionality for SageMath. If you are interested, you can read my write-up.
