Darshan Purandare

I received a PhD in Computer Science from the University of Central Florida. I was a member of the NetSec lab at the School of Electrical Engineering and Computer Science, and was advised by Professor Ratan Guha. The main focus of my research was to provide media streaming to large swarms using Peer-to-Peer (P2P) network.

Currently, I work for Bing platform team at Microsoft. In the past, I have worked on open source Samba project.
