I am a PhD student in the Security and Privacy Engineering Laboratory led by Prof. Carmela Troncoso at EPFL. My research interest is privacy engineering and applied cryptography. As an example, my last project was a collaboration with the Internation Committee of the Red Cross on the Pribad project. Together, we examined the digitalization of humanitarian aid distribution systems and proposed a scalable design that provides formally provable security, privacy, and accountability.

More recently, I am exploring the following directions:

  • Censorship resistance in the Chinese context
  • Digital safety of investigative journalists
  • Technology, modernization of law, and policy

Generally speaking, I am interested in understanding the asymmetry of this world. I ask myself whether, how, and why we shall use the asymmetry of computational complexity in cryptography to balance out the asymmetry of power in the real world. Although I am having a lot of fun trying to find a mathematically provable and practical solution from the lens of a systematic design, I must be honest that many times the answer to the first question is negative, i.e., computation cannot solve everything.

Previously, I got my master’s degree in Electrical Engineering and Information Technology at ETH Zürich. Before coming to Switzerland, I got my Bachelor’s Degree in Communication Engineering at Harbin Institute of Technology in 2019.

I love dancing and running, just in the same way as I love my work. From time to time, I write silly posts (in Chinese) on random things. As you may have noticed while reading those (not necessarily non-fictional) posts, I am very proud of my dialect 纯正辽西东北话 ;)
