👋Lipeng (Tony) He

I am a student, software engineer, and researcher at the University of Waterloo.

My research interests span Computer Security and the Theory & Applications of Cryptography (especially across computing and data sciences). My general goal is to enable society to gain the benefits of emerging technologies without sacrificing security & privacy.


In my previous experience, I worked on developing and analyzing secure systems and protocols that address issues related to:

  • Trustworthy Machine Learning
  • Blockchain security and scalability

More recently, I have been focusing on the research area of AI safety & alignment.


My general objectives are to:

  • Design and develop systems and protocols that are provably secure, inexpensive and easy-to-use;
  • Support the deployment of security and/or cryptographic solutions in the real world to improve the safety, privacy and robustness of computing systems;
  • Find new and innovative ways to apply cryptographic tools in society.

In the process of achieving these objectives, I hope to also unlock new application scenarios through a combination of systems design and cryptography.
