Welcome to my home page!

I am an Assistant Professor in the Department of Computer Science at University of Missouri-Columbia. My research and development areas of interest include: Distributed and Cloud Computing, Computer Networking, Networked-Multimedia Applications, Cyber Security. I enjoy working with students in the "VIMAN Lab" - Virtualization, Multimedia and Networking Lab.

I obtained my M.S. and Ph.D. degrees from The Ohio State University, and B.E. from Bangalore University. Before coming to MU in 2013, I was a Research Director at Ohio Supercomputer Center/OARnet, The Ohio State University. I am an expert consultant for industry, academia and government agencies in the design and development of software systems comprising of advanced architectures and cloud-based performance analysis technologies.
