Research Areas - Computer Architecture and Systems Security.
Memory Systems Lab, Georgia Tech

I am a PhD candidate (expected graduation: May’22) in ECE at Georgia Tech, USA, advised by Prof. Moinuddin Qureshi. My research interests in computer architecture and security include cache side-channels, transient execution attacks, Rowhammer attacks, DRAM integrity, memory safety and fuzzing.

[CV] [Research Statement] [Teaching Statement] [Diversity Statement]

My research envisions a future where hardware is secure and free from vulnerabilities, and where trustworthy hardware enables low-cost pervasive security for software systems.

My research has enabled principled security for future hardware and systems at several layers:

  • Cache memories: Enabled the fastest known cache timing attacks [1], randomized cache defenses [2] ending an arms race, and one of the first academic hardware defenses against Spectre [3].
  • DRAM memories: Enabled DRAM integrity solutions [4, 5] that protect against physical attacks, and principled Rowhammer mitigations for current and emerging attacks like Half-Double and Blacksmith.
  • Software reliability: Enabled hardware support for low-cost memory safety [6] and fuzzing [7] that makes software resilient to bugs causing a large majority of current vulnerabilities.

For my work, I have been awarded an IEEE MICRO Top Picks Honorable Mention, the Georgia Tech (IISP) Cybersecurity Fellowship, and the Georgia Tech (ECE) Bourne Fellowship.

I received my B.Tech & M.Tech in Electrical Engineering at Indian Institute of Technology - Bombay, India.
