# Research

My current research interest is in machine learning (ML) and deep learning (DL) in fiber optic sensing technologies. I am interested in bringing in various mathematical tools into practical ML/DL algorithms that are designed for specific industrial tasks.

Previously, I worked on diverse topics in mathematics, including:

discrete random integral matrices (especially p-adic matrices),

random algebraic curves over finite fields, and

connections between arithmetic, combinatorics, and topology.
