About me

I strive to create things on the computer that are simultaneously novel, interesting, and useful.

I am currently known for:

  • creating Online Python Tutor, a free educational tool for learning computer programming, which has been used by over 500,000 people in over 165 countries,
  • writing The Ph.D. Grind, the first known detailed account of an entire Ph.D. experience, which has been downloaded over 100,000 times,
  • and creating one of the first Ph.D. dissertations on software tools for computational scientists; one such tool, CDE, has been used by over 10,000 people.

Years before I began sharing my writing and software publicly, I originally created this website to showcase my childhood photography hobby.
