A pic of me.

Hi, I'm Christopher Strelioff and you've found my home on the internet. All my friends call me Chris -- you should too. This page has links to some of my projects, ranging from visual and sound experiments using html/css/javascript to my publications on topics as varied as Bayesian inference, evolutionary biology, chaos theory and disease surveillance.

I am very interested in the use of science, mathematics, art and programming as tools to do creative things. I would love to help out on any project that promotes these ideas. If you are in the Wisconsin -- especially the Eau Claire area -- and are looking for help with an idea of this type please get in touch. I have a special place in my heart for activities that are inclusive, making a special effort to welcome all types of people -- varied age, race, gender, income-level, etc.


sandbox 2014 - current

This is my current blog, where I discuss a variety of computing topics including Ubuntu Linux, vim, python and javascript as well as science and statistics material like Bayesian inference and machine learning techniques. Many of the posts have accompanying gists, which contain code for the example discussed.

vizdiv 2015 - current

As the name might suggest to you, this url is a place to post my experiments with web-oriented visualization using html, css, javascript, svg etc. All examples have code available at github.

sound-room 2016 - current

A collection of sound and music related experiments. At this point I'm mostly focused on playing with the web audio api -- making sound with the browser and building html/css/js tools for visualizing and interacting with sound -- get in touch if you are interested!

conjugate 2015 - current

A project to implement statistical inference for distributions with conjugate priors -- binomial, multinomial, categorical, Gaussian, etc in a Python 2.7+ and 3.3+ compatible package. Because the focus is on distributions with conjugate priors, the posteriors are also analytic and no MCMC is needed. If you're interested and/or would like to help out please contact me -- links above.

livesoncoffee 2012 - 2014

This was my blog at wordpress between 2012 and 2014, covering topics related to using Ubuntu 12.04 for scientific computing. During this time the site has attracted more than 50,000 views and now averages 100 views per day. I know, small potatoes, but it's not bad for a little blog about installing Python, R and vim on Ubuntu 12.04!
