About

I am a Machine Learning Research Scientist at Apple MLR, primarily working on NLP and Audio pretraining. I am working closely with Navdeep Jaitly in Samy Bengio‘s team. Currently, I am interested in large-scale text-speech modeling, long-form sequence modeling, and factualness, consistency, and robustness of language models.

I received my PhD degree from the University of Waterloo, worked on language modeling and unsupervised machine learning under the supervision of Ming Li and worked closely with Jimmy Lin.
Before that, I worked with Chengqing Zong on spoken language understanding.

I am an area chair of EMNLP, and an outstanding reviewer of ICML.
I am one of the PRS challenge organizers of Embodied AI Workshop in CVPR 2024.
I have been serving as a reviewer of ACL, EMNLP, ICML, Neurips, ICLR, AAAI, COLING, etc. since 2019.
