Research Interests

induction and restriction are adjoint

  • Cryptography, computer security, provable security.
  • Probability theory, Markov chains, theory of majorization.
  • Algebras, noncommutative groups and rings in (cool) applied math settings.

Amusements

  • My Erdös number is 4 (Lee-Markus-Kakutani-Erdös). I've personally met all but Shizuo Kakutani ... maybe if I write a crap novel, Michiko will insult me in person?
  • From relays to mechanical integrators to cryptosystems, Claude Shannon seemed intrigued by how series and parallel combinations would correspond to "+" and "*" in some algebraic structure. Amusing ...
