I currently lead the global next-generation network and edge computing practice for GTS TCIS (IBM Global Technology Services - Technology Consulting and Implementation Services). I am an IBM Distinguished Engineer, a Master Inventor, and a member of the IBM Academy of Technology. Prior to my current role, I spent 3 years building and operating a partner ecosystem for GTS with late-stage venture-funded startup companies. I built partnerships in software defined storage/resiliency/networking, automation, AI-ops, monitoring and hybrid cloud management. I started my IBM career at the TJ Watson Research Center in Yorktown Heights, initially working on distributed middleware technology (Websphere XD), and later in various management positions in the IBM Research Services division, working on service quality, automation technology and AI for services: contract health (P&L) prediction, AIops, application modernization, and service request automation. My work led to numerous research and outstanding technical accomplishments and allowed the GTS business to demonstrate significant improvements in service quality and cost.
Before IBM I was the CTO of Voicemate, a dot-com era startup that pioneered mobile authoring technology for the finance industry. I started my career as a networking researcher at AT&T Bell Labs working on early concepts of network programmability and network and system management technology for the then rapidly-growing Internet backbone. For my work on network, systems and service management I received the 2017 IEEE Dan Stokesberry award for "the most distinguished technical contribution to the growth and understanding of integrated network management."
Over the course of my career, I acquired an extensive background in distributed systems, cloud, networks, middleware, service management and analytics. I am a frequent attendee of several conferences on these topics, I have authored or co-authored more than 60 peer-reviewed technical publications and delivered numerous tutorials and invited keynotes. I served as the Technical Program Co-Chair for the 2001 IFIP/IEEE Integrated Management. I was a founding editor of the IEEE Transactions on Network and Service Management where I served in its editorial board until 2011. For a brief period I was also an adjunct faculty at Columbia University teaching courses on network management technology and practices. I have worked and consulted extensively on all aspects and stages of the innovation lifecycle, from design, financing, prototyping, development to strategy and steady-state operations.
I received the M.S., M.Phil. and Ph.D. degrees in electrical and computer engineering from Columbia University, with a focus on next-generation networks and distributed systems, and a B.S. degree in electrical engineering and computer science from the National Technical University of Athens. I am affiliated with the Japan Karate Association and Shotokan Karate-Do International where I hold a 4th degree black belt and the rank of A-class instructor.
