Computer Science

I work at Google.

My primary interests are in algorithms, systems, security, 
theory, and programming languages.

I was Director of Research at Qualys, where I worked extensively on IronBee.  Before that, I was Director of Research at Nemean Networks which was acquired by Qualys on August 31, 2010.  I was a research assistant with the Wisconsin Advanced Internet Laboratory at the University of Wisconsin–Madison.  I also worked in the Flux research group at the University of Utah, primarily as a developer of Emulab.

Mathematics

I received my Ph.D. in Mathematics from the University of Wisconsin–Madison in May 2007.  My advisor was Steffen Lempp.  My focus was mathematical logic specializing in computability theory.

Dance

I dance with Madison Folkdance Unlimited.  I am also a coordinator for the Door County Folk Festival.
