I am a Professor Emeritus, Computer Science, at Sonoma State University. I received a PhD in electrical engineering with an emphasis on bioengineering from the University of California, Berkeley. My research career continued for another seven years at the University of California, San Francisco. My decade of industry experience began with analog circuit design for spacecraft. I migrated to software engineering early on and worked on projects ranging from a CT scanner to a shipping container handling system. Almost all my programming was in assembly language, on four different processors. I went into teaching later in life, which brought new challenges, including three more processors. During my twenty plus years of teaching my specialty was assembly language. I also taught most of the core courses in our curriculum, in addition to many electives.
