Who I am

I am a PhD student at Stony Brook University focusing on computer networks and network measurement. I work as a research assistant for Dr. Phillipa Gill.

What I do

I have a special interest in figuring out how the Internet is actually laid out, how data is treated by networks and providers that pass it along, and general issues related to net neutrality. My research is currently focused on these topics.


Aug. 2016: I will attend USENIX Security 2016 in Austin, TX to present our poster titled "A client-side analysis of TLS usage in mobile apps" (abstract|poster)
Feb. 2016: Attending HotMobile 2016 in Washington, DC to present our poster titled "Haystack: In Situ Mobile Traffic Analysis in User Space" (abstract|poster).
Aug. 2015: I will attend USENIX Security 2015 in Washington, DC.
Jul. 2015: Our paper titled "Identifying Traffic Differentiation in Mobile Networks" has been accepted into ACM IMC 2015!
Jun. 2015: I will be a graduate research intern at UC Berkeley's International Computer Science Institute (ICSI) for this summer.
Jan. 2015: I have been awarded the ICFP fellowship to work with Citizen Lab as a visiting research fellow
Aug. 2014: Our poster was the runner up at ACM Student Research Competition at SIGCOMM '14 (abstract|poster).
Sep. 2014: I won best poster at SBCS Technology Day!

    • In Situ Mobile Privacy Leaks Detection and Measurement Platform
      As part of my work as a graduate student intern at ICSI, I helped develop a mobile application that enables detection of private information exfilteration by applications without requiring root access by implementing a VPN interface on the device.
      I developed the module responsible for intercepting encrypted communication on the device (TLS proxy). The mobile application, called "Haystack", is available to download from the Google Play Store.
    • Information Controls Lab (ICLab)
      ICLab is a platform designed for repeatable measurements to detect and analyze information controls and Internet interference at scale. It's a joint work between The Citizen Lab, Stony Brook University, and Princeton University.
      I have been working on developing and deploying the open-source ICLab software platform called Centinel. The software platform supports running custom measurements across any collection of vantage points across the globe and analyzing measurement results using the ICLab data management platform (DMP).
    • Mobile Middlebox Detection
      A joint effort between Northeastern University and Stony Brook University, the mobile middlebox detection project aims at detecting interference introduced by middleboxes in the mobile environment by running active measurements from the edge. These measurements include detecting traffic differentiation for different applications using a novel record-replay method. The differentiation detection application is available to download from the Google Play Store.
