He has significant experience with international telecommunication standards (ITU-T SG15/Q4), and has directed collaborative projects with several automotive/truck manufacturers and vendors (Ford, Mercedes-Benz, DaimlerChrysler, Freightliner, Gentex, Visteon).

He has significant experience as an expert witness in patent infringement and product liability cases in the automotive and telecommunication areas; 100% of his cases resulted in a win or a very favorable settlement for his clients. In 2017, he was the lead expert witness in a case that resulted in a $25M jury award for his clients; this decision was later upheld on appeal. His deep technical expertise allows him to analyze patents and products in detail, and explain clearly (in expert reports, depositions, and court testimony) the main issues that the judge and jury need to internalize in order to comprehend the essence of the case.  His extensive educational experience allows him to help judges and jurors understand the topic they are dealing with, instead of confusing them with unnecessary technical details.

After all, it takes excellent teaching skills and a deep understanding of a complex technical concept to convey the essence of that concept to non-experts without talking down to them.
