Young
Building intelligent systems with mathematical rigor.
From predictive AI & statistical models to numerical simulation, turning real and complex problems into elegant, efficient solutions.
Featured Projects
A selection of projects spanning data science, mathematical modeling, and machine learning.
Quantitative Thinking
Methods, not just tools. How I approach prediction, risk, modeling, and applied problem solving.
Prediction & Forecasting
Probability estimation, calibration, and time series forecasting. Building models where the confidence interval matters as much as the point estimate.
Risk, Uncertainty & Decision Logic
Quantifying what could go wrong and by how much. From hypothesis testing to sensitivity analysis, grounding decisions in statistical evidence.
Mathematical Modeling & Simulation
Translating physical and biological systems into equations, then solving them numerically. PDEs, dynamical systems, and optimization under constraints.
Applied Across Domains
Energy infrastructure, environmental science, public health, betting markets. The methods transfer; the problems keep the work grounded.
Got a problem worth solving?
Whether it's a technical challenge, an ambitious idea, or something still taking shape, I'd be glad to hear about it.
