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.
Spring 2020: Advanced Networking and Distributed Systems
The course will be a hands-on introduction to networking (how is the TCP protocol designed and implemented?), distributed systems (how can we build fault tolerant distributed software that handles network failures or malicious code?), and cloud computing (how can we combine a collection of cloud services to build complex web applications?). Since this is the first time it is being taught I don’t have a full syllabus to share, but there will be lectures and projects covering the above topics. You should expect it to be fairly programming intensive (group projects) and you might need to pick up some new languages along the way (C, java, python).
Undergraduates are recommended to have taken Operating Systems and Graduate students should have taken Distributed Systems. Priority will be given to students with this background, but others will be allowed in if space permits. Fill out this form if you are interested.
