About me

I am a researcher in the Systems Research group at NEC Laboratories America. My research spans the areas of networking and distributed systems and (r)evolves around the duality of data analytics and system design. I enjoy measuring and analyzing networked systems to understand their operation and identify opportunities for improvement. I then use the results of measurements to design better systems or better manage existing ones.
