Research
I am generally interested in applied cryptography and blockchains. I am currently focusing on two research topics:
1. Robust and efficient design of blockchain protocols.
2. Efficient privacy-preserving computation.
I'm looking for students
I am always looking for highly motivated Ph.D. students. If you are interested in working on any of these topics, then:
