UC Berkeley — Applied Mathematics
Byron Delaney Jr
Quantitative Finance & Data Science
Building rigorous quantitative systems — from credit risk models to portfolio optimizers — grounded in applied mathematics.
About
Applied Mathematics.
Financial Precision.
I studied Applied Mathematics at UC Berkeley, where I developed a strong foundation in statistical theory, linear algebra, and optimization — the mathematical backbone of modern quantitative finance.
My work sits at the intersection of finance and machine learning. I build systems that model credit risk, optimize portfolios, and extract signal from complex financial datasets — always with a focus on rigor, interpretability, and practical impact.
I'm actively seeking roles in quantitative research, financial analysis, and data science where mathematical depth and computational execution both matter.
