Liang studied for his Ph.D. in Machine Learning at CMU before joining Facebook as a Research Manager. He builds cutting-edge AI to understand, inspire, and connect people to what's most meaningful. He develops algorithms and systems to learn everything about and around people and optimizes services to help them achieve what they care about. Liang's work involves ranking, retrieval, deep learning, sparse/graph/sequence modeling, reinforcement learning, optimization, large-scale training, and ML platform. His work intersects cutting-edge research and massive real-world applications and impact.
