Welcome

 

I am a Ph.D. candidate in the Department of Computer Science at Virginia Tech.

As a member of the SyNeRGy laboratory I work under the supervision of Prof. Wu-chun Feng, Dr. Mark Gardner and Eric Brown.

My research interests include networking, parallel computing and performance evaluation of systems. Recently, I have been working on a communication model for next generation networks.

When I am not working, I follow my photography pursuits.

About Me

Brief Biography

Umar Kalim (öö·m·ãr   k·ä·l·ē·m) is a Ph.D. candidate in the Department of Computer Science at Virginia Tech. He is working as a graduate research assistant and is sponsored by Juniper Networks. He received his M.Eng. degree from Kyung Hee University (KHU), South Korea and his B.E. degree from National University of Sciences and Technology (NUST), Pakistan.

Before he joined Virginia Tech, he was working at the Stanford Linear Accelerator Center, Stanford University where he developed algorithms for network anomaly detection by measuring and analyzing performance metrics. He also developed software/tools for measurement of network performance metrics, their aggregation and visualization.

He was also involved in the development of a network analysis system for specialized analysis of "Voice over Internet Protocol" (VoIP) traffic. The system is currently in use for monitoring, managing and authorizing service providers. (This project was developed under an agreement reached between NUST and Pakistan Telecommunication Company Limited (PTCL).
