Brief Biography

I studied mathematics as an undergrad at Boston University. Continuing at Harvard, I completed my Ph.D. in 1999. Concurrent with these studies, starting in 1989, I worked as a consultant and software engineer on a variety of projects, many of which involved quantitative analysis in the finance industry. After completing my degree, I spent some time doing some interesting international travel, and also became interested in cryptography.   In 2000, I joined RSA Laboratories pursuing research topics in cryptography and data security. In 2007 I joined Akamai as a software developer. My Curriculum Vitae can be found here:   Szydlo C.V (PDF)

Some Manuscripts and Presentations (Mathematics)

This thesis work involves explicit constructions of Néron models, extensions of Tate's Algorithm to compute the special fiber of an elliptic curve to the non perfect residue field case, and the resolution of singularities on elliptic schemes.
