Andrew B. Collier

I am a Physicist and a Data Scientist. I work on a diverse range of projects, mostly in R and Python, although I dabble in a range of other technologies. I enjoy public speaking and delivering training. I strive to make data and code more accessible, taking complex concepts and breaking them down into smaller, digestible units.
