I am a second year graduate student in the Computer Science and Artificial Intelligence Laboratory, at MIT . Before coming to MIT, I spent four awesome years at the Department of Computer Science and Engineering at IIT Madras, India.

I work with Prof. Dina Katabi on wireless networks.

ZigZag Decoding: Combating Hidden Terminals in Wireless Networks
Shyamnath Gollakota and Dina Katabi
ACM SIGCOMM, 2008.

This paper presents ZigZag, an 802.11 receiver that combats hidden terminals. ZigZag allows collisions to take place but attains the same throughput as if the colliding packets were a priori scheduled in separate time slots.
Embracing Wireless Interference: Analog Network Coding
Sachin Katti, Shyamnath Gollakota and Dina Katabi. ps, pdf
ACM SIGCOMM, 2007.

This paper presents ANC which performs network coding on signals instead of bits. We show that ANC provides significantly better gains in mesh networks when compared to digital network coding.
Round-Optimal and Efficient Verifiable Secret Sharing
Matthias Fitzi, Juan Garay, Shyamnath Gollakota, Pandu Rangan and K. Srinathan. ps, pdf
TCC, 2006.

This paper presents an efficient 3 round protocol for VSS. The solution is based on a 3 round solution of the so-called weak verifiable secret
sharing (WSS), for which we also prove that three rounds is a lower bound.
