My research interest span the areas of wireless network systems design, network measurement and performance analysis. I currently focus on building reinforcement learning based self-driving wireless network management system for quality of experience (QoE) optimization. In the past, I built non-traditional networking systems for challenged environments, with an emphasis on optimizing QoE on mobile broadband. I developed Lumos, a robust and scalable system that can accurately detect congestion and overload in LTE and 5G networks using passive measurements. The applicability of Lumos spans from emergency networks to post-disaster scenarios.

I’m a fourth-year PhD Candidate in the Department of Computer Science at UC Santa Barbara where I work in MOMENT Lab, advised by Prof. Elizabeth Belding. I also work very closely with Prof. Arpit Gupta.

Excited to have our work featured in CNET. Mapping cellular coverage is more nuanced than can be inferred from inaccurate FCC Broadband Maps, and has major implications for Internet access for millions of Americans. Our work takes a step towards fixing this. You can find the article here.

Our work on “Estimation of Congestion from Cellular Walled Gardens using Passive Measurements”  was accepted to IEEE Transactions on Mobile Computing.


18 December 2020

Our paper “Too Late for Playback: Estimation of Video Stream Quality in Rural and Urban Contexts” was accepted to PAM 2021

24 February 2019

MOMENT lab will be traveling to HotMobile 2019 in the beautiful city of Santa Cruz, California. See you there!

Internet Measurement conference (IMC '19)

Presenting our work on estimating overload in congested LTE networks using just passive measurements from off-the-shelf networking gear. Glad to report that our work received a lot of support from the networking community.

Apart from research, I dedicate a fair bit of time towards photography. I usually do landscapes, travel and portraits,
but experiment with other forms occasionally.


I have been lucky to visit several countries in Asia, Europe, North America and Africa. Check out some of my travel photography.
