Introduction

I grew up in India and studied at Chinmaya International Residential School. I moved to Singapore to pursue my bachelor’s degree in Physics and PhD at the National University of Singapore. I continued there as a Research Fellow and later as a Senior Research Fellow, before moving to Oxford in 2022 as a Marie Skłodowska-Curie Fellow. In 2024, I was selected as a Young Scientist for the Lindau Nobel Laureate Meeting and was awarded the Royal Society University Research Fellowship, through which I established my research group, Designer Quantum Materials for Devices. I took up my current position at Queen’s College and the Department of Materials in 2026.

Teaching

I teach across the Materials curriculum, connecting fundamental principles of physics to explain the properties and functions of materials. I also supervise undergraduate projects and DPhil students. Previously, I have worked with the Ministry of Education (Singapore) to develop fun and engaging demonstrations for science education. I am also an advisor to the non-profit: Raising a Mathematician Foundation.

Research

My research is driven by the ambition of designing the ‘Silicon of tomorrow’: new materials that could unlock technologies beyond what is possible today. My group explores quantum materials, where interactions between electrons, spins and atoms can give rise to remarkable collective properties. By tailoring these interactions, we aim to design materials with bespoke functions. Our work has led to the discovery of nanoscale topological magnetic states that can be controlled through materials design. We are now learning to harness these states and their exceptionally fast dynamics to develop ultrafast and energy-efficient information technologies.
