Thank you for stopping by. Let’s explore how we might work together and how I can help your business thrive through better business intelligence and less risk exposure.

Expert consulting

I help companies make better decisions by taking advantage of the data they have, combining it with expert opinion, creating mathematical models, overcoming computational difficulties, and interpreting the results. I work with clients ranging from solo entrepreneurs to some of the world’s largest software and biotech companies.

I am a consultant in applied mathematics, statistics, and software development. Some particular areas in which I help companies:

My background

I completed a PhD in applied math at University of Texas and a postdoc at Vanderbilt. My research focus was non-linear partial differential equations. After my postdoc I decided to leave academia. I worked as a software developer and project manager for several years.

In 2000 I came to MD Anderson Cancer Center, first as a software development manager, then as a research statistician. My work centered around Bayesian statistics, clinical trials, and numerical algorithm development.

I now work as a consultant, combining my previous experience in applied math, statistics, and software development. I live with my wife and our four children in Houston, though work takes me around the world.

“John’s consulting was exactly what we needed. Brilliant, amiable, a clear communicator, and easy to work with, he gave us the intelligence we needed to grow a client by 40% in a competitive global market. He saved us hundred of hours of work by knowing exactly how to approach our analysis out of dozens of possible models. I can’t recommend him more highly.” — Brian Toomey, CEO, JB Analytics
