I am a theoretical physics postdoc in the School of Natural Sciences at the Institute for Advanced Study in Princeton, NJ. Beginning February 2018, I will be a research scientist at Facebook AI Research in NYC.
I am interested in the interplay between physics and computation. My work in theoretical physics has focused on the relationship between black holes, quantum chaos, computational complexity, randomnesss, and how the laws of physics are related to fundamental limits of computation.
Previously, I completed my Ph.D. at the Center for Theoretical Physics at MIT, funded by a Hertz Foundation Fellowship and the NDSEG. Prior to that, I was a Marshall Scholar in the UK. While there, I read for Part III of the Mathematical Tripos at Cambridge and then studied quantum information at Oxford. In a previous life (undergrad), I worked on invisibility cloaks (metamaterials and transformation optics) with David R. Smith.
My name is very common, so I try my best to publish under more parts of my full name Daniel Adam Roberts—which I never go by and which (unfortunately) also happens to be very common.
Some of my work focuses on what happens when something falls into a black hole (in anti-de Sitter space). The black hole will very quickly scramble (but not destroy) the information. Black holes are thermal systems, and this is actually a manifestation of the well-known butterfly effect. We can try to think about this process in terms of its computational complexity, or we can study it as a distinguishing feature of quantum chaos.
AI and Machine Learning
At FAIR, I hope to focus on applying tools from theoretical physics to gain insight into machine learning and artificial intelligence.
I also organize an online journal club hep-ai for discussions of machine learning and AI papers from a theoretical physicist’s perspective. Let me know if you’re interested in joining!
