Expert Witness Code 4856
Professional Summary:

This Ph.D. has over 35 years of industry and academic experience covering a broad swath of hardware and software engineering, having worked in the computer chip industry for 16 years (at AMD, Integrated Device Technology, ComCore/National Semi and Semtech), along with a 6 year stint in aerospace (Hughes Aircraft Doctoral Fellow). While providing technical support for all IC products for customers all across the western US, his chief focus was microprocessors (i8085/8048, Z80/Z8000, Am2900, MIPS R3000/4000) and their attendant software development systems and test/integration tools (ICE, logic analyzers).

He has a unique perspective on the computer chip industry, having been involved since the early days of Fairchild Semi in the mid 1960s (while still in high school), then observing the founding of Advanced Micro Devices in May 1969, for whom he later was employed as a field applications engineer for software and systems. (he has chronicled the "genesis" of Silicon Valley in an article plus org chart.)
