Other email addresses (private Google doc) — I maintain a few other private email addresses for projects/topics that I want to pay attention to in batches, and keep them listed in this document for a small number of correspondents.

Email policy:
I receive a large number of emails that I cannot always respond to, so I tend prioritize emails coming from a short list of collaborators, and from threads that I have initiated myself. If I do not respond to your message, I apologize. Thanks for understanding!

Instant messaging policy:
I generally find that instant messaging services (such as Facebook Messenger, Slack, WhatsApp, or mobile SMS services) are poorly used relative to their attentional costs. For example, a message that requires thought or communication with others is a “to-do” item that is better processed as a part of system such as Gmail with the capability to mark messages as “done” separately from marking them as “read” (e.g., by archiving them), and the capability to compare many similar to-do items against each other for improved prioritization (e.g., using labels/filters). So, by default I am not very responsive to instant messaging, except from close friends and co-workers who already have a good understanding of when I think instant messaging is appropriate.

What I’ve been doing

Since February, 2017 I’ve been a researcher in the field of AI safety at the Center for Human-compatible AI, in the Department of Electrical Engineering and Computer Science at UC Berkeley. My research aims to identify mathematical issues with the safety of future artificial intelligences… sort of like cybersecurity, but for future, non-human agents. I think the impact of AI on future civilizations is likely to be huge, and I think working to make that impact as positive as possible is a huge opportunity to do good for humanity.

Prior to this, from 2015 to 2017 I was a research fellow at the Machine Intelligence Research Institute in Berkeley, CA. Before that, I worked as a quant / stock trader / data scientist for a financial trading firm in New York City. Before that, in September 2013 I took leave from a mathematics postdoc at the NSF Mathematical Biosciences Institute in Columbus, Ohio, to build and expand the Center for Applied Rationality (CFAR) in Berkeley. And just before that, in May 2013 I finished my PhD in mathematics under  Bernd Sturmfels at UC Berkeley, with mentor  Shaowei Lin. My thesis research was in algebraic statistics, with applications of  algebraic geometry to the study of  causal inference and machine learning models. I switched from pure algebraic geometry to algebraic statistics in fall 2011 because machine learning has become so incredibly cool that I just can’t help thinking about it.

Also during my PhD between 2011 and 2012, I cofounded the Center for Applied Rationality in Berkeley, which is now a registered 501(c)(3) non-profit with 7 full-time employees and many volunteers. CFAR runs workshops teaching techniques for rational decision-making and action-taking, on the basis of empirical findings in cognitive science, and of course, data collected from previous workshops. It’s the best education per-dollar I’ve ever seen available, anywhere. Check it out.

My name

“Critch” is not a nickname someone made up by combining words; it’s my real last name, from birth.

Where I’m from and where I’ve been

I was organically grown in a tiny fishing village of about 250 people called Hillview in Newfoundland, Canada, where I learned how to be happy, and I proudly consider Newfoundland English to be my native language. I attended high school in Clarenville, Newfoundland (class of 2004), and went to Memorial University of Newfoundland for my undergrad (class of 2006). Then I started my PhD studying analytic geometry at the University of Toronto, but soon decided that I liked algebraic geometry more, so I got an MSc from Toronto instead (class of 2008), and started a new PhD in algebraic geometry at Berkeley. I moved to Rome in January, 2010, where I was a visiting scholar at Università degli Studi Roma Tre. I moved back to Berkeley in August, 2010, to New York City in April, 2014, and back to Berkeley for a third time in September, 2015… if you noticed a pattern here, you’re right: Berkeley is definitely my favorite place to live so far 🙂
