I am looking for motivated PhD students to join my group at the University of Toronto. If you find security exciting, please reach out and apply to the UofT CS/ECE graduate programs.
My research focuses on security for computing hardware and systems. My research interests include microarchitectural security (cache side-channels, transient execution attacks, Rowhammer attacks), system security (memory safety and fuzzing) and security for machine learning systems (LLM side channels, GPU Confidential Computing).
My work has been awarded an IEEE Top Pick in Hardware and Embedded Security, HPCA Best Paper Award, IEEE HOST Best PhD Dissertation Award, ACM SIGARCH / IEEE TCCA Outstanding Dissertation Award (Honorable Mention), ACM SIGMICRO Dissertation Award (Honorable Mention), and an IEEE MICRO Top Picks (Honorable Mention). My PhD was partly supported by a GT Cybersecurity Fellowship and a GT Bourne Fellowship.
I received my PhD at Georgia Tech, Atlanta, USA, where I was advised by Prof. Moinuddin Qureshi. I received my B.Tech and M.Tech at Indian Institute of Technology - Bombay, India. Prior to UofT, I was with NVIDIA Research.
