Expert Witness
Jack Ganssle works as an expert witness in matters related to embedded systems.
Embedded systems are devices with microprocessors that aren't PCs. Examples include mobile phones, electronic medical equipment, and even smart toys. A modern car has many dozens of embedded systems to control the infotainment, engine, brakes, and much more.
Embedded systems are particularly challenging as they are the synthesis of software - which can be millions of lines of cryptic code - and hardware that can pack over a billion transistors on a single chip. Power management, handling real-time constraints, making a system safe and secure, handling sensors and actuators, and dozens of other requirements means a typical system is an exquisite synergy of hardware and software (also called "firmware"); neither can be understood in isolation.
Voted the "Most Significant Embedded Individual" by Embedded Systems Design readers and winner of the 2014 ACE Award for contributions to electronics, Jack is uniquely qualified in both embedded hardware and software/firmware issues. He was the only embedded person on NASA's Super Problem Resolution Team, created by the Space Shuttle Columbia Accident Investigation Board to harness the expertise of highly-respected people from outside of the agency. His forty-five-year career has been entirely in the embedded world and has always bridged the hardware/software divide. Whether it's C code or digital circuitry, analog interfacing or an HDL, Jack has the experience and skills to help your team prevail.
As an accomplished author (six books and over 1000 published articles), Jack writes expert reports that clearly explain complex technology to non-engineers. His teaching skills, honed by 30 years of presenting seminars to companies and papers at conferences (including many keynote speeches), help the various parties understand the issues at hand.
Jack has testified in depositions, District Court and before the ITC. He is located outside of Baltimore, MD, convenient to firms in the Washington, DC area.
