I am an assistant professor at the Dept. of Computer Science and Engineering, IIT Hyderabad. My research interests are program analysis, program understanding, automated concurrency testing, and high-performance computing. Prior to joining IIT Hyderabad, I was a post-doctoral researcher at Microsoft Research Lab, Bangalore. I received my PhD (+M.Tech) from IIT Madras, supported by the TCS PhD fellowship. Before that, I worked as a Software Engineer at Hewlett Packard, Chennai.
I am broadly interested in program analysis, program understanding, automated concurrency testing, and high-performance computing. Specifically, I work on designing new (or enhancing existing) program-analysis techniques for practical applications, with the main focus on the challenges related to scalability and interoperability. I am also interested in devising techniques to achieve scalable performance, correctness and programmability in real-world systems that appear in varied environments: single-core/multicore, heterogeneous and distributed systems.
Here are some of the projects I worked on. (Give you a flavour of my research!)
Drop me an email if you are a motivated student with similar research interests and want to work with me.
- A Language-agnostic Concurrency Testing Library: Designed for developers to build their own custom systematic testing solutions. The library detects concurrency bugs by taking over the scheduling of concurrent operations (tasks/threads/actors etc.) and systematically exploring the various interleavings of operations.
- Testing Storage-backed Applications Against Weak Isolation Levels:
Develops a mock storage system that exercises weak behaviors possible under multiple isolation levels to detect assertion violations in a database/KV-store application. The operational semantics of this storage system is based on axiomatic definitions of various weak isolation levels.
- Identifying Refactoring Opportunities in Large Codebases: It involves proposing efficient static analyses (mainly points-to analyses) for automatic identification of challenging refactoring opportunities in object-oriented software, with particular emphasis on the issues that occur when the refactoring tools are coupled into resource-bound environments like IDEs (Integrated Development Environments).
- TTLG: An efficient tensor transposition library for graphics processing units (GPUs), which implements specialized data movement strategies and uses a performance prediction model to achieve high coalesced access of data.
- Approximate Nearest Neighbor Search (ANN) on GPUs: It is an efficient ANN search implementation on GPUs for improving the QPS (Queries Per Second) throughput up to >50,000 on 100-dimensional billion point data (coming from deep learning-based embeddings).
