Hello and welcome! I’m a Ph.D. scholar at BITS Pilani, Pilani Campus (Rajasthan), working at the exciting crossroads of nanotechnology, clean energy, and advanced sensor design. My research is all about building the next generation of hydrogen sensors using ultra-wide bandgap porous Ga₂O₃ semiconductor nanostructures — devices that could one day make hydrogen-based energy systems safer and more reliable.
I enjoy wearing two hats in my work:
On one side, I dive deep into the world of simulations, using Density Functional Theory (DFT) and Molecular Dynamics (MD) to understand how atoms and molecules behave at the tiniest scales.
On the other side, I roll up my sleeves in the lab, where I synthesize semiconductor nanostructures and fabricate real devices, turning theory into working technology.
Before starting my doctoral journey, I worked as a Research Project Fellow at IIT Patna, where I explored the potential of perovskite solar cells. That experience not only strengthened my interest in energy materials and semiconductor devices but also resulted in several publications in reputed international journals.
At my core, I am driven by curiosity and collaboration. I believe great science happens when people from different fields come together, share ideas, and build solutions that matter. I’m always open to new collaborations, interdisciplinary projects, and academic discussions.
