A path from economics and data science to stochastic OR and industrial research.

My background combines formal training in economics, data science, and social engineering with research roles that require mathematical models to survive contact with real operations.

Teaching

Intuition first, then formalization and implementation.

I have taught online courses in Foundations of Reinforcement Learning, Mathematical Optimization, and Mathematics for AI. My teaching approach combines intuitive examples, visualization, hand calculations, and Python implementation so learners can move from a real decision problem to a mathematical representation and then back to interpretation.
