If technology doesn't work for the most vulnerable, it doesn't work at all.

I am currently pursuing a Master’s degree in Computer Science, focusing on Human-Computer Interaction and Ubiquitous Computing at Aarhus University, Denmark.

I received my Bachelor’s degree in Computer Science and Technology from Harbin Institute of Technology, Shenzhen (HITSZ). During my undergraduate studies, I worked as a research assistant at the ai{DEAL} Studio, School of Design, Southern University of Science and Technology (SUSTech), advised by Dr. Pengcheng An. I am currently a research intern at the AI4SG Lab at the National University of Singapore (NUS), supervised by Dr. Yi-Chieh Lee, and previously interned at the Interactive Matter Lab at Aarhus University, supervised by Dr. Michael Wessely.

My research interests include human-computer interaction related to health and social computing. My passion lies in using AI technologies and/or wearable devices to enhance human well-being, aiming to improve people’s lives. Additionally, I am keen on analyzing information from online media/apps to understand how digital platforms reflect and influence specific communities.

I like engaging in interdisciplinary exchanges and collaborations with all fields. Feel free to email me if you are interested in collaborating or discussing research ideas. I look forward to generating thought-provoking discussions!

🔈I am actively seeking for 2026 Fall PhD position, please don’t hesitate to contact me if you think I might be a good fit!

🫂 Friends

I’m truly thankful to my friends (or more than friends) who have supported and been there for me both in my studies and in life. I’m so glad our paths crossed💐.

  • Holly Tianqi Song (PhD candidate at NUS. I met Holly by chance on RedNote. We share similar academic interests and are trusted friends and collaborators🥰.)
  • Chenyi Zhang (PhD candidate at University at Buffalo SUNY. We met and became good friends and collaborators while we were both visiting students at SUSTech. Wish Chenyi all the best on her journey in the United States.)
  • Kexin Huang (Master Student at SUSTech. Kexin was like “family member” to me at SUSTech.)
  • Yijing Jiang (PhD candidate at Aarhus University. A “strict” and “pushing” boss, but those late nights rushing for UIST over McDonald’s and KFC are truly unforgettable.)
  • Zimo Xia (Master student at NUS. Yes, we are both furry fandoms and shared similar research interests.)
  • Haiyang (Dylan) Xu, Ge (Kacy) Fu, Yunhui Song (My Master’s classmates at Aarhus University. We collaborated on multiple projects and shared countless enjoyable moments together😁.)
  • All the people who love me and whom I love.
