My name is Roy and I'm a data scientist in Houston, Texas. I am currently working at Arundo, a startup helping companies more efficiently use their equipment and assets. I am also the founder of Zefs Data Science, but my consulting is currently on hold.

By training I am a physicist. My PhD focused primarily on Monte Carlo-based radiation simulations aimed at improving cancer treatments. Nowadays I focus on the broad application of computational data analysis, modeling, and visualization.

This site is home to some of my data projects, occasional blog posts, and links to my other web presences.
