I ran the Forum for three years. I'm no longer an active moderator, but I still provide advice to the team in some cases.
I'm a Communications Officer at Open Philanthropy. Before that, I worked at CEA, on the Forum and other projects. I also started Yale's student EA group, and I spend a few hours a month advising a small, un-Googleable private foundation that makes EA-adjacent donations.
Outside of EA, I play Magic: the Gathering on a semi-professional level and donate half my winnings (more than $50k in 2020) to charity.
Before my first job in EA, I was a tutor, a freelance writer, a tech support agent, and a music journalist. I blog, and keep a public list of my donations, at aarongertler.net.
