Biography

Yancheng Wang is a Machine Learning Researcher at Apple, where he works on on-device multimodal LLMs and reasoning. Before joining Apple, he interned at Meta Superintelligence Labs (MSL), Amazon AWS AI, Amazon Alexa AI, and Kuaishou U.S. R&D Center, where he worked on LLM post-training, multimodal learning, LLM-powered agents, and neural architecture search. He recently completed his Ph.D. in Computer Science at School of Computing and Augmented Intelligence, Arizona State University, supervised by Professor Yingzhen Yang. His research focuses on LLM reasoning and agents, LLM post-training, multimodal learning, efficient and robust vision encoders, diffusion models, and synthetic data. His work has been published in leading venues including ICML, ICLR, NeurIPS, ACL, TPAMI, IJCV, UAI, NAACL, and AAAI.
