I’m a Applied Mathematics + Computer Science undergraduate at Columbia University interested in quantitative research, machine learning, optimization, and systems. My interest sits in between Math, Algorithms and Economics. I’m especially drawn to work that combines rigorous modeling with strong implementation, whether in research code, open-source tools, or high-performance systems.
