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.

Please don't contact me through any other channel about something that should be handled through this site. If you do, I'll probably just tell you to post it here.

Any responses to moderator messages, or comments on official moderation actions here, will be ignored if sent through external channels!
