Structural Properties of Flagpole Partitions

Feb 2025 - Present

Learned about \(q, t\) Catalan numbers, Dyck vectors, and their connection to integer partition structures. Working on finalizing the proof of conjecture on second-order tail initiators via explicit inverse mappings between flagpole partitions and flag types.

Mentor: Professor Kyungyong Lee

Past Research Experience

Finite-Size Effects in Epidemic Models

May 2025 - Dec 2025

Co-developed agent-based and mean-field SIHRS models incorporating immunity waning to capture recurrent epidemic waves. Employed a martingale-based early-time-step method to identify non-linear amplification of finite-size effects. Validated theoretical predictions via numerical simulations calibrated to county-level COVID-19 data.

Mentors: Professor Chuntian Wang, Professor Yuanyuan Song, Professor Yuanzhen Shao

Game of Cycles on Maximal Plane Graphs

Feb 2024 - June 2024

Defined "IO Maximal Plane Graphs" and analyzed invariant properties to determine the game outcome. Established that the winning strategy is determined by the parity of the graph's vertices.

Mentor: Professor Malgorzata Marciniak

Method of Brackets and Bessel Function Integrals

June 2023 - Aug 2023

Applied the "Method of Brackets" to provide rigorous proofs for entries involving Bessel functions of the first and second kind from the Gradshteyn and Ryzhik tables.

Mentor: Professor Victor H. Moll

Continued Fractions, \(a\)-Fibonacci Numbers, and Middle \(b\)-Noise

Mar 2023 - Aug 2023

Generalized the continued fractions [1,..., 1, 3, 1,..., 1] to [a,..., a, b, a,..., a] using \(a\)-Fibonacci sequences. Showed that the \(a\)-th metallic ratio limit is invariant under the middle noise term \(b\).

Mentor: Professor Cheng-Han Pan
