I’m Nathaniel Wesley Filardo (among other names). Born in 1984 (how time flies), I recently acquired my Ph.D. in Computer Science at Johns Hopkins, as part of the Dyna programming language effort. I have recently become a postdoc in the the CTSRD team at Cambridge University, primarily thinking about temporal integrity for capability systems.

A list of my publications is available here.

My CV is available here.


The easiest ways to contact me are:

  • Via email: my initials at
  • Via XMPP: my initials at; the cclub jabber server supports full federation.
  • IRC (efnet, freenode, oftc, ircnet, voidnet): I can typically, again, be found by my initials.

Of late I have adopted use of a Yubikey as a PGP smartcard. The private bits exist only in the smartcard and my offline key management machine; the public bits available here (the authentication subkey is available in ssh format). The key’s fingerprint is

For the moment, I am also still using my older keys, too; they are all signed by
