About me

I am a fifth year Ph.D. student at Center for Speech and Langauge Processing, Johns Hopkins University. I study natural language processing (NLP), advised by Prof. Benjamin Van Durme.

Before my Ph.D. study, I obtained a bachelor’s degree in Physics (with a double major in computer science) at Peking University. For internship, I visited Microsoft Research Asia (mentored by Chin-Yew Lin), Semantic Machines (mentored by Anthony Platanios), and Microsoft Research at Redmond (mentored by Corby Rosset). I was also a visiting student at Johns Hopkins University in 2018, mentored by Hongyuan Mei and Jason Eisner.

My research

I am interested in language representation, especially for long texts. I aim to represent the text in a structured manner rather than token-wise representation like vanilla Transformers. I also work on its applications, such as efficient language models.

In the past, I worked on other fields such as (ordered by reversed time): information extraction, prompting (for which I won the Best Short Paper award in NAACL 2021), time-series analysis, and data-to-text generation.


I am more known as hiaoxui, who developed Walless(PKU). Walless is a platform that helps Chinese netizens to circumvent Great Firewall. For over 7 years, I have been developing and funding this non-profit project to help tens of thousands people to access the global internet without censorship.

My name

My name is 秦光辉 in Chinese. Guang’hui is pronounced like kwang-huei. Qin is like Chin.
