I am a Ph.D. student in the School of Computer and Cyber Sciences at Augusta University in Georgia, USA, since 2024. I am also a Graduate Research Assistant in the school.

My research focuses on distributed algorithms, with a particular interest in the consensus problem in synchronous systems. Currently, my work explores complexity trade-offs in a resource-constrained model called the sleeping model (First introduced by here), where the goal is to design a distributed protocol while players (or nodes) choose either to be awake or asleep (active or inactive). Then we try to provide time-optimal but also highly efficient in terms of energy consumption algorithms. I am generally interested in the foundations of theoretical computer science, including complexity theory and the analysis of distributed protocols.

This website serves as a central hub for my research activities. You can find a list of my publications, current projects, and occasionally, posts about topics that I find interesting.

We study fault-tolerant consensus in a variant of the synchronous message passing model, where, in each round, every node can choose to be awake or asleep. This is known as the sleeping model (Chatterjee, Gmyr, Pandurangan PODC 2020) and defines the awake complexity (also called \emphenergy complexity), which measures the maximum number of rounds that any node is awake throughout the execution. Only awake nodes can send and receive messages in a given round and all messages sent to sleeping nodes are lost. We present new deterministic consensus algorithms that tolerate up to f
