Hello there! I'm Gayatri

I'm a quantitative researcher studying macro-financial systems, stochastic modeling, and market microstructure at Columbia University.

I work at the intersection of econometrics, financial modeling, and system design — building frameworks where the math has to be right and the system actually works.
