Hi there! I'm HDE, a PhD student in astronomy. I work on pulsar timing, focusing on detecting gravitational waves and looking at weird pulse profiles. I also enjoy long-distance running, crosswords, hot chocolate and a good book, though usually not all at once.

I'm an elected moderator on Worldbuilding, and a pro-tem mod on History of Science & Mathematics, Mythology, and Astronomy. In bygone days, I moderated Interpersonal Skills.

He/him pronouns, please.
