I am a 3rd year Ph.D. student working with Prof. Mohit Tiwari at UT Austin. I am a graduate researcher at the SPARK Research lab with a focus on Computer Architecture and Security in Systems.
I am currently exploring the facets of micro-service architectures and impact of it on server architectures. The stateless design pattern, single-threaded application workload and heavy use of network communication do not leverage current architecture's high performance gadgets. I am also interested in security implications of such systems in a large scale cloud environment.
In the past I have worked on both micro-architectural side channel attacks and defenses. Our work, Cyclone, is a contention based side channel malware detector system which was published in MICRO '19. The work detects such attacks by tracking fine grain cyclic domain interference among attackers and victims. We also show that such a detector works for same-address space side channels (e.g. Meltdown type attacks).
My collaborative work with Prof. Chris Fletcher from UIUC explores Speculative Inference Attacks, where we introduce new types of attack vectors that can still undermine state-of-the-art defense mechanisms for speculative or transient attacks.
I completed my undergrad in Electrical Engineering with Minor in Computer Systems from India from Indian Institute of Technology, Kanpur in 2015. I worked at VMware R&D, India for 2 years as a Software Developer before joining UT Austin for my Ph.D.
