I'm an amateur mathematician. I'm mostly interested in recreational mathematics and combinatorial games. I like algebra, number theory, and cryptography too.

Once I was President and CEO of a little public-key cryptography company [website archive] that was (eventually) acquired by VeriSign, but there wasn't much in the way of "real" mathematics involved in that—it was software development instead.

Here's a trophy I've kept from graduate school.
