Teaching Assistant, September 2001 - December 2001

Dept. of Electrical and Computer Engineering, University of California, Santa Barbara, CA

Conducted laboratory and discussion classes in upper-division Digital Signal Processing. Supervised and assisted students with lab and homework.

Hardware/Software Engineer, July 1998 - July 2000

Tiernan Communications, San Diego, CA.

Designed and maintained hardware and software for MPEG-2 encoders, modulators, demodulators, and decoders. Tasks included verifying product requirements with marketing, writing high level designs, designing circuit board schematics, PCB layout, writing control firmware in C, designing FPGA logic, testing and debugging, and coordinating with production for quality testing.

Summer Intern, June 1997 - September 1997

TRW, Avionics Systems Division (bought by Northrop Grumman Corporation), San Diego, CA.

Developed schematic logic and timing models for electronic components in the TRW concurrent engineering library. These models were used for board-level functional simulation on various projects throughout TRW.
