Aditya Grover

I am a research scientist in the Core ML team at Facebook AI Research. I also collaborate with Pieter Abbeel at UC Berkeley as a visiting postdoctoral researcher. In Fall 2021, I will join UCLA as an assistant professor of computer science.

My research is centered around machine learning for probabilistic modeling, unsupervised representation learning, and sequential decision making, with applications at the intersection of physical sciences and climate change.

Previously, I completed my PhD at Stanford University (2020) and my bachelors at IIT Delhi (2015), both in computer science. During my PhD, I spent wonderful summers interning at Google Brain, Microsoft Research, and OpenAI. At Stanford, I created and taught a new course on Deep Generative Models with my advisor Stefano Ermon.
