I am a PhD candidate working with my advisor Bobby Bhattacharjee. While I am broadly interested in networking and systems research, my dissertation research focuses on enabling users to reliably express policies over the I/O data processing on their devices.

Drowsy Project Icon

Drowsy Power Management
Employs dependency tracking to wake only the necessary system components when devices resume from a suspended state, thereby reducing energy consumption.

D-Root Project Icon

D-Root DNS Server
Measurement and analysis of the query traffic sent to the D-Root DNS root nameserver, which is hosted by University of Maryland.

EbN Project Icon

Encounter-based Networking
Designing a privacy-preserving communication system for mobile social applications based around 'encounters`' between users (and their devices).
