Summary of Technical Expert in the Legal Domain

I have been retained as a testifying expert and consulting expert in computer hardware, software, and networks in about fifty cases since 1995. In about two thirds of these cases my role was as a testifying expert, where I testified over twenty times and wrote more than fifty expert reports and declarations. My current focus is on providing consulting expert services.

Most expert work has centered on distributed systems, including client-server computing, operating systems (including device drivers), networks, runtime systems, file management system, secuity & protection, object-oriented technologies, Internet applications, and colloaboration systems. Besides these horizontal technologies, cases have addressed a spectrum of application domains including:

• Telephony, particularly cellular telephones
• Mobile and small computer technology e.g., eBook readers, navigation systems, and set-top boxes
• Web services, e.g., stateless servers, file servers, image services, virtual terminals, smart clients, dynamic HTML, streaming content, and scripting languages
• Vertical services, e.g., check imaging, tax software, wholesale/retail systems, sales support systems, and plumbing & HVAC design

My experience has evolved from diverse perspectives of computer technology:

• Researcher in hardware and software systems (from 1972 to 1980 and from 1986 to 2010)
• Product developer, manager, and executive in the commercial computer industry (from 1980 to 1986 and in 2000-2001)
• Industry consultant (since 1986),
• Technical expert in the legal domain (since 1995)
