My work at IBM Research spans the areas of distributed systems, automation, analytics, cognitive computing and service management.
Between 2006 and 2016 I was the Sr. Manager for the IT Services Automation department at the TJ Watson Research Center, leading a research program on hybrid cloud (IaaS and PaaS), analytics, business process modeling and automation for service delivery. In that capacity I worked closely with IBM’s Global Technology Services on improving the quality and efficiency of IBM’s managed services portfolio. The work led to numerous research and outstanding technical accomplishments and allowed the business to demonstrate significant improvements in service quality and cost. Earlier at IBM, I worked on high-performance distributed middleware technology to optimize and manage virtualized resources. That work led to the WebSphere Virtual Enterprise product.
In late 2016, I joined IBM’s global technology services (GTS) to lead the formation of an incubation lab in Silicon Valley that works with early stage companies on hyper-converged systems, software-defined storage, networking, hybrid cloud and IT analytics. I have also taken on the role of product manager for IBM’s self-service delivery offering.
Before IBM, I was the CTO of Voicemate, a venture funded startup that pioneered voice authoring and workflow technology for the financial markets. I started my career at AT&T Bell Labs and later AT&T Labs-Research working on network and service management for the early Internet. I was one of the founding editors of the IEEE Transactions on Network and Service Management, where I served on the editorial board until 2011. I also served as guest editor on the Journal of Networks and Service Management. In 1998 and 1999 I was adjunct faculty at the department of Electrical Engineering at Columbia University.
Over the course of my career, I acquired an extensive background in cloud, networks, middleware, service management and analytics. I am a frequent attendee of several conferences on these topics, I have authored numerous peer-reviewed publications and delivered tutorials and keynote presentations. I served as the Technical Program Co-Chair for the 2001 IFIP/IEEE Integrated Management. 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 Ph.D., M.Phil. and M.S. degrees in electrical and computer engineering from Columbia University, 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.
In May 2017 I received the 2017 IEEE Dan Stokesberry memorial award "in recognition of the most distinguished technical contribution to the growth and understanding of the field of intgrated network management."
