I am a first-year Ph.D. student at the Language Technologies Institute of Carnegie Mellon University supervised by Prof. Carolyn Rosé. I am also collaborating with Prof. Daniel Fried. Before entering CMU, I obtained my Master degree in the data mining group at the University of Illinois Urbana-Champaign supervised by Prof. Jiawei Han.

I have broad interest in NLP and data mining. My previous/ongoing research topics include pretrained language models, information extraction, summarization, taxonomy construction and graph algorithms. I currently work on improving the pre-training of text-to-text language models to obtain better sequence embeddings. This can be applied to downstream tasks such as dense retrieval and recommendation.

Previously, I completed the Bachelor study in computer science and mathematics in Hong Kong University of Science and Technology, where I received the Academic Achievement Medal.
