Hi, I’m Cas.
scasper[at]mit[dot]edu
Hi, I’m Stephen Casper, but most people call me Cas. I’m a second year Ph.D student at MIT in Computer Science (EECS) in the Algorithmic Alignment Group advised by Dylan Hadfield-Menell. I’m supported by the Vitalik Buterin Fellowship from the Future of Life Institute. Formerly, I have worked with the Harvard Kreiman Lab and the Center for Human-Compatible AI. My main focus is in developing tools for more interpretable and robust AI by studying interpretability, adversaries, and diagnostic tools in deep learning.
You can find me on Google Scholar, Github, Twitter, or LessWrong. If you want to get to know me, I made an autobiographical document to introduce myself to people and make friends. I also have a personal feedback form. Feel free to use it to send me anonymous, constructive feedback about how I can be better. For now, I’m not posting my resume/CV here, but please email me if you’d like to talk about projects or opportunities.
You can also ask me about my hissing cockroaches, a bracelet I made for a monkey, witchcraft, what I learned from getting my genome sequenced, jumping spiders, a time I helped with a “mammoth” undertaking, a necklace that I wear every full moon, or a jar I keep in my windowsill.
