About Me

My main research focus is on the implementation security (mainly fault cryptanalysis aspect) of cryptographic algorithms.

I am also interested in the following topics:

  • Efficient implementation of SAT/SMT solvers
  • Theorem provers and their applications
  • Web3 and decentralized networks

I also love typesetting related stuff.
