👋Tony (Lipeng) 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).
I think broadly about the privacy, security and trustworthiness of modern computing systems; this intersects with areas such as:
- Trustworthy Machine Learning (ML Security & Privacy)
- Blockchain Security and Scalability, and
- Secure Computation
Through a combination of systems design and cryptography, I hope to make existing systems more useful and secure, while also unlocking new application scenarios.
