• Hobbies: Longboard 🛹, guitar 🎸, customization 🔧, chat 💬
• Some Fun Facts:
  • 🌟 Participated in the Canton Fair twice, where I successfully traded with many overseas friends and earned my first significant income (which I spent on an iPad Pro). I have to say I hate India accent (they are good partners tho).
  • 🏥 Interned at the General Hospital of the People’s Liberation Army in Beijing, working as a physicist in the oncology department. I was responsible for dose control and QA/QC.
  • 🤓 Realized women (no offense but) slow me down coding.
  • 🧑‍🤝‍🧑 Have 10+ boy friends.
  • 🗣️ Taught 100+ on oral English for free (sometimes for a coke).

• 2020-2024: Southern Medical University, specializing in Oncology Radiology.
• 2024-: Chinese University of Hong Kong, pursuing Biomedical Engineering.

• 📄 The m6A methyltransferase METTL3 affects cell proliferation and migration by regulating YAP expression in Hirschsprung disease
• 📄 Association of rs2435357 and rs2506030 polymorphisms in RET with susceptibility to Hirschsprung disease: A systematic review and meta-analysis
  • Role: Data processing and visualization
  • Published on: 2022, as undergraduate
