Research:
Georgia Tech School of Mathematics | Atlanta, GA
Research Assistant
Fall 2023 – Present
- Advised by Dr. Ernie Croot.
- Explored the Kirchhoff Matrix-Tree Theorem and researched domino tiling enumerations on a grid to attempt to strengthen existing bounds.
- Researched maximal induced forests in multi-dimensional grid graphs; found and proved bounds with a construction giving a tight upper bound for two-dimensional graphs, but discovered these results were already found in Caragiannis et al. (2002).
- Found an upper bound of $3n^2/4$ for the size of maximal induced 4-cycle-free subgraphs in two-dimensional grid graphs. Proved upper and lower bounds on the number of such subsets with $(3/4 - \varepsilon)n^2$ vertices by considering local $2 \times 2$ subgrids and identifying a necessary constructive condition.
- Our work resulted in the paper 4-cycle-free induced subgraphs of grid graphs; presented at MAA-SE 2026.
Quad Packing Research Group | Remote
Research Assistant
Spring 2025 – Present
- Advised by Dr. Timothy Goldberg (Lenoir-Rhyne University) and Dr. Lauren Rose (Bard College).
- Select participants from the 2024 Polymath Jr REU plus other researchers met at JMM 2025.
- Proved an exact expression for the flat ($r$-dimensional affine subspaces of a vector space $V$) number, showing that each term $M(n)$ can be written as the sums and products of certain combinations of powers of 2 in the binary representation of $n$.
- Proved quad packing is equivalent to flat packing via an injective mapping, resolving a conjecture in a 2023 MIT Primes paper.
- Our work resulted in the paper Quad-packing in the game EvenQuads; presented at MAA-SE 2026, contributed to JMM 2026.
Williams College | Remote
Participant (2024), Graduate Research Mentor (2025)
Summer 2024, 2025
- Worked in the Games and Finite Geometry team of the Polymath Jr REU, advised by Dr. Timothy Goldberg (Lenoir-Rhyne University) and Dr. Lauren Rose (Bard College).
- Researched the quad number $q(n)$ in the card game Quads; wrote C++ code to brute-force results for $n \in [4,16]$ and $d=\lceil \log_2 n \rceil$.
- Mentored $20$ undergraduates, introducing them to the research problem and the game itself through resources and weekly meetings.
- Proved upper bound expression for $q(n)$ and attainability for $n$ a power of two; presented at JMM 2025 and MAA-SE 2025.
Georgia Tech School of Modern Languages | Atlanta, GA
Research Assistant
Summer 2024
- Advised by Kyoko Masuda.
- Researched frequency of female versus male pronouns in the manga Sazae-san and drew conclusions based on different age groups.
- Submitted collaborative research paper in Japanese to the SGSJ in 2024; presented at SGSJ 2024.
Georgia Tech School of Electrical and Computer Engineering | Atlanta, GA
Research Assistant
Fall 2023
- Worked in the Retrofuturistic Hardware team under Dr. Aaron Lanterman.
- Translated docs of the Japanese NEC PC-FX game console to English, storing 12 files of 15k+ lines in Github Pages.
- Researched the PC-FX’s address map, register list, and I/O access space and the specs of its sound processing device.
- Analyzed the C Compiler of the GMAKER Starter Kit (processing flow/registers), allowing user-made software to run.
- Wrote graphical software in C with the kit to run on the PC-FX to showcase its usability to a team of 3 and a professor.
