Timothy W. Wood
SEH Room 4580
I am an Associate Professor of Computer Science at George Washington University and one of the directors of the GW Cloud Systems Lab. I teach and do research in the general areas of operating systems and distributed systems. I am particularly interested in how new virtualization technologies can provide application agnostic tools that improve performance, efficiency, and reliability in cloud computing data centers and software-based networks. My research focuses on practical, systems-level challenges created by emerging technologies in these areas. I received my Ph.D. in CS from UMass Amherst in 2011 and my B.S. in ECE from Rutgers University in 2005.
