Researcher

Lin Xiao

Also known as 肖林

Lin Xiao is a research scientist at Meta's Fundamental AI Research lab, where his current research interests include large-scale optimization and reinforcement learning. Early in his career, he was one of the winners of the Young Researcher Competition at the first ICCOPT in 2004, for work on fastest mixing Markov chains. He published the dual averaging method for regularized stochastic learning at NIPS 2009, and the paper received the Test of Time Award at NeurIPS 2019. He spent 14 years at Microsoft Research before joining Facebook in 2020. In 2025, he received the ACM SenSys Test of Time Award for robust distributed sensor fusion based on average consensus.
