I have served in an executive role at Cogo Labs (formerly Adverplex) since the company's founding in 2005. I was the founding Chief Technology Officer of the company, became Chief Scientist upon my return to academia in 2007, and have served on the Board of Directors since 2008.

From 1998 to 2003, I served as an Affiliated Scientist at Digital Fountain, Inc., and I co-authored the digital fountain paper (Proc. of ACM SIGCOMM '98, recipient of the ACM SIGCOMM Test of Time Award in 2009) that described the networking applications and primary benefits of the underlying technology, fast erasure codes.

In the 1990s, I served as an instructor and educational consultant at Hewlett-Packard, Inc. My primary responsibility was teaching the Software Job Skills class, a full-time, 17-week retraining program that gave HP engineers the basis for a new career in software development.
