I am currently a Senior GenAI Research Engineer at NatWest Group and a Visiting Researcher at the University of Birmingham. Previously, I was a Systems and Performance Researcher at Brave and a Senior Research Scientist in the Device Intelligence team of the Device Software Research department at Nokia Bell Labs in the UK. I was also a Visiting Scholar at the University of Cambridge. My research interests span generative AI and applied machine learning for mobile and ubiquitous systems, including Federated Learning, On-Device Learning, and TinyML.

Prior to joining Bell Labs, I completed my Ph.D. (with an institute fellowship) in the Department of Computer Science and Engineering at the Indian Institute of Technology Kharagpur, where I worked under the supervision of Prof. Sandip Chakraborty and Dr. Bivas Mitra. During my Ph.D. I worked on mobile and ubiquitous systems with a primary focus on the behavioral dynamics surrounding human activities. I am an alumnus of the UbiNet Research Group and CNeRG.
