Dr. Kanellakopoulos is a Technology leader with 25+ years of experience in R&D, operations, administration, and management, in both academia and industry. He has authored or co-authored books, numerous articles in peer-reviewed technical journals and refereed technical conferences, and multiple standards contributions. He is also the co-inventor on more than 25 patents. He has been the plenary speaker at major technical conferences, and an invited speaker at more than 40 industrial and academic venues in 12 countries across 4 continents.

In his industrial career, he Designed and Built Telecom Products such as DSL and Carrier Ethernet hardware and software, and has significant experience with international telecommunication standards (ITU-T). He has also worked in wireless communications (3GPP, Wi-Fi), primarily on digital signal processing methods for baseband transceivers.

In his academic career, Dr. Kanellakopoulos conducted research on adaptive control of nonlinear systems, with applications to automotive control systems, specifically ADAS (adaptive cruise control, blind spot monitoring, lane keeping, vehicle collision avoidance) and active suspension. He directed a project on automation of heavy-duty vehicles as part of the California PATH Program; one of the most visible results of this research was the “Variable Time-Headway” algorithm for adaptive cruise control, which was demonstrated on a fully-automated heavy-duty (Class 8) 18-wheeler truck and has found widespread use in current adaptive cruise control systems. His UCLA team also designed and built a prototype full-size fully-automated electric vehicle that has been used for research purposes on multiple college campuses.

Dr. Kanellakopoulos has directed collaborative projects with several automotive/truck manufacturers and vendors (Ford, Mercedes-Benz, DaimlerChrysler, Freightliner, Gentex, Visteon).

He has consulted for clients such as technology companies (on intellectual property strategy and product development), private equity firms (on due diligence for investment), and law firms (on expert witness matters).

He is an IEEE Fellow and a recipient of multiple national and international awards.
