Ted Moskovitz
I'm a member of technical staff on the Multimodal team at Anthropic. I'm interested in understanding and building helpful intelligence with a grounded understanding of the world. Broadly, I'm excited about reasoning, sequential decision-making, and optimization for large-scale models.
Before this, I did my PhD at the Gatsby Computational Neuroscience Unit in London, where I was advised by Maneesh Sahani and Matt Botvinick. I've also interned at DeepMind, where I worked on constrained reinforcement learning, and Uber AI Labs, where I worked on optimization for large-scale deep learning.
I sometimes put notes, code, and other writing here.
