Thank you for visiting. I’m John Cook, and this is my personal web site. This page tells you a little about me and the kind of work I do.


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.


My blog The Endeavour has short, self-contained articles on a variety of topics, technical and non-technical. You can also find me on Twitter and .

Articles and presentations

Here are some journal articles and technical reports I’ve written, and some informal articles I’ve written on software. See my blog for many more articles.
