Who Am I

Mission statement: Make the greatest possible positive social impact using data science. I believe in helping others around you propser, whether through working a socially benefical career, writing free data science articles to educate others, or volunteering in one’s community. We all have choices to make, and I’ve decided to devote my career to trying to improve human sustainability, which I think can be done most effectively as a data scientist working in the energy sector.

Contact me

If you have a data science question or would like to dicuss anything data science related I’m responsive on Twitter or directly at wjk68@case.edu. If you do contact me, please remember I’m doing this on a volunteer basis.

Live Code

Most about pages are pretty dull. To mix things up, I’ve included a live Python editor where you can edit and run code. Thanks to repl.it for making this possible.
