🙋 About Me
I am a second year Ph.D. student at the University of Cambridge, working under the supervision of Prof. Nigel Collier. Previously, I completed my MPhil degree at Cambridge, focusing on fact-checking under the guidance of Prof. Andreas Vlachos and Dr. Zhijiang Guo. During my undergraduate studies, I completed my capstone project with Prof. Wenjie Li on conversational QA systems and interned at UCLA under the supervision of Dr. Nanyun Peng.

👀 More facts about me:
Volunteer Teaching
During term breaks, I volunteered in various teaching trips to rural areas globally, covering Hong Kong, Taiwan, Guilin, Ho Chi Minh City (Vietnam), Phnom Penh (Cambodia), and Trà Vinh (Cambodia). I've participated in 10+ voluntary services, accumulating 400+ service hours, benefiting 300+ students. Also, I joined the United Nations' Millennium Fellowship 2021 to promote equal education.
Mandarin Debate
As a member of both the PolyU and Cambridge Mandarin Debate Teams, I participated in competitions across various cities, including Singapore, Shanghai, Suzhou, Nanjing, Wuhan, Changsha, Xi'an, and Chengdu. These experiences refined my communication and critical thinking skills and provided international representation opportunities.
