Jan Sacha

Antwerp, Belgium
Systems Researcher



I'm a researcher in the Wireless Networks program in Bell Labs Antwerp. Currently I'm focused on software architectures for the Long Term Evolution (LTE). Previously, I was working on a novel operating system prototype, Osprey, tailored for high-performace and real-time computing. In 2009 and 2010 I was a postdoc in the Computer Systems group at Vrije Universiteit Amsterdam where I was working on middleware and operating system support for a large-scale Grid. In 2009 I received a Ph.D. degree in computer science from Trinity College Dublin, Ireland. In 2004 I received an M.Sc. degree in computer science from both University of Warsaw and Vrije Universiteit Amsterdam.

Note: At the end of April 2014 I'm moving to the IP Division in Mountain View, CA. I'm going to work there on the SR-OS operating system for high-performance routers.
