I am currently with the Network Architecture team at Google where I focus on SDN-based configuration and management of Google's production networks. I also work on measurements and analysis that provide operational insights into backbone and datacenter networks, and on design of new networking abstractions for Google's infrastructure cloud platform (GCE). Previously, I was the Chief SDN Architect in the System Networking Division at IBM, responsible for overall SDN product architecture and open source technical strategy (e.g., OpenDaylight, OpenStack). In this role, I worked across architecture, engineering, testing, product management, and sales teams to deliver IBM SDN products to the market. I spent nearly 15 years at the IBM TJ Watson Research Center, leading teams working on problems related to SDN, cloud networking, and infrastructure and management in public and private clouds. At IBM Research, I also worked on content distribution networks, Web performance, network measurement, network route control, and online games infrastructure. I have managed highly-talented technical teams, and also coordinated research and development across globally distributed teams. I have published over 50 technical articles in a variety of top-tier research conferences, workshops, and journals, and have been issued a number of patents on inventions related to systems and networking.
