I do not respond to off-site contact about moderation. Any moderation questions or comments should go on meta, or bring it up in chat.

I'm a postdoc doing research in high-energy particle physics. I also have a hobby interest in computer programming.

You can find me on Twitter, or check out my blog and personal website! Or you can email me at stack@ellipsix.net.
