Printable Download: Michael Barr Profile and CV

Barr Group co-founder Michael Barr is a former adjunct professor of electrical and computer engineering with many years of hands-on software design and implementation experience. Internationally recognized as an expert in the field of embedded software process and architecture, Barr has been admitted as a testifying expert witness in U.S. and Canadian court cases involving issues of reverse engineering (including DMCA), interception of encrypted signals (Federal Communications Act), patent infringement, theft of copyrighted source code (including trade secrets issues), and product liability.

Barr's software has powered millions of embedded devices. He is also the author of three books and more than seventy published articles and papers about embedded systems design. For more than a decade, he was a regular invited speaker at the Embedded Systems Conferences around the world and, at times, served as a member of the conference's advisory board and as chair for various tracks.

2016 Embedded Systems Safety & Security Survey

Barr Group's 2016 Embedded Systems Safety & Security Survey had participation from more than 2,500 embedded systems design engineers and revealed a number of interesting trends in the embedded industry. In this webinar, Barr Group executives Michael Barr (CTO) and Andrew Girson (CEO) discussed some of the most interesting findings.

Killer Apps: Embedded Software's Greatest Hit Jobs

Between 1985 and 1987, there were at least 6 distinct accidents where the Therac-25 radiation therapy machine delivered up to 100 times the prescribed radiation dose, resulting in injury and death. These high-profile accidents demonstrated that embedded software can be dangerous, even lethal. In the decades since, and despite increasing regulation, safety-critical system failures have continued to kill people.

As embedded software's size and complexity continue to rapidly progress, user safety increasingly relies upon safe and reliable firmware implementations. Nowhere is this more evident than in the automotive industry, where self-driving vehicles are a much-hyped and potentially invaluable part of our future.

Barr Group co-founder and CTO Michael Barr presents an engaging discussion of the past, present, and future of embedded software safety.
