Stephen A. Edwards is a tenured associate professor in the Computer Science Department of Columbia University. He obtained his Ph.D from the University of California, Berkeley in 1997, his MS from Berkeley in 1994, and his BS from the California Institute of Technology in 1992, all in Electrical Engineering. Before pursuing his academic career in 2001, he worked for two Electronic Design Automation (EDA) companies, Simplex Solutions, now part of Cadence, and Synopsys.

Professor Edwards and his group explore automating the creation of software for embedded systems: application-specific computers hiding in a growing number of industrial and consumer systems. They have developed numerous compilation techniques for the Esterel synchronous language for real-time control and are also developing domain-specific languages for device drivers and communication protocols.

My group does not offer internships, summer or otherwise.

Consulting/Litigation Support/Expert Witness Services

I have been engaged as an expert witness in various patent litigation cases involving software and computer architecture, including ITC cases. I am always interested to hear about new opportunities.
