Currently, I am working as a postdoc at Rutgers University in New Jersey. My alma mater is PřF and FI MUNI. I strive to bridge beautiful theory (e.g., mathematics) with useful practice (e.g., cryptology) both in my research and out of it.

  • elliptic curves, algebra, and number theory (elementary, algebraic, and computational)
  • applied cryptography - mainly assymetric one, e.g. isogeny- or multivariate-based,
  • cryptanalysis of implementations, primitives and standards,
  • utilizing algebraic and lattice methods to attack implementations through side channels.
