Online writing

Math blog

I host a math blog called Hard Arithmetic where I try to discuss whatever math topics I find interesting, with a special focus on those things which once confused me. I have not had as much time in recent years to work on blog posts (although there are many partially done!), but hope to return soon to more frequent writing.

math.stackexchange

I have been a long-time contributor to the website math.stackexchange. I have tried to answer questions there with the same guiding theme as my blog -- things that I once found confusing, and are hard to find in the literature for a beginner.
