I am a PhD candidate at the College of Computing. I am a member of the Networking and Telecommunications group. I work with Prof Mostafa Ammar. My research interests are in scalable adaptive video streaming over the Internet. Previously, I worked on message ferry routing in Disruption Tolerant Networks (DTNs).
In 2009 I worked with Prof Nick Feamster on discovering VLAN induced dependencies in Georgia Tech campus network.

In 2011, I spent seven months interning at Google in the Quantitative Latency group. I worked on a very interesting project that aims at uncovering the pop-level topology of the Internet.

In 2012, I interned at Cisco and did some interesting work on the buffer bloat effect of HTTP adaptive streaming.
