I am a physicist working on neural networks and machine learning. I am a member of the research staff at the MIT-IBM Watson AI Lab and IBM Research in Cambridge, MA. Prior to this, I was a member of the Institute for Advanced Study in Princeton, NJ. Broadly defined, my research focuses on the computational properties of neural networks. Particularly, I am interested in implementing ideas coming from neuroscience and physics in modern AI systems. I received a PhD in Physics from Princeton University in 2014.
