I am a third year PhD student at the University of Illinois at Urbana-Champaign, where I work with Aishwarya Ganesan and Ram Alagappan at the DASSL Lab. I am broadly interested in distributed storage systems, with a focus on designing abstractions for new and emerging application paradigms.
Lately, I have been working on distributed shared logs, which power a wide range of modern applications. My recent projects focus on designing new shared log abstractions (see SpecLog, LazyLog) that overcome the high latencies inherent in traditional shared log architectures, addressing the needs of latency-sensitive applications such as real-time analytics and high-frequency trading systems.
In the past, I have interned at the systems group at Microsoft Research India where I worked with Akash Lal on applying concurrency testing techniques on production-scale distributed systems.
I graduated with a Dual Degree (Bachelors and Masters) in CSE from IIT Madras, where I worked with Kartik Nagar on cutoff-based techniques for verifying distributed protocols.
