About

I am a researcher working at the intersection of data science, deep learning, computational electromagnetics, RF/microwave engineering, and photonics. Currently, I serve as a Research Fellow at Macquarie University in Sydney, where I focus on developing phased-array RF systems for satellite communication (SATCOM) applications.

I previously worked as a Project Scientist (post-PhD) at IIT Madras, where I developed a Physics-Embedded Solver for electromagnetic (EM) problems. Before that, I was at NTT Research in Sunnyvale (also post-PhD), where I created solvers to model the electromagnetic eigenmodes of optical waveguides in anisotropic media using the finite-difference method.

Most recently, I completed my Ph.D. in the NEMO Lab at IIT Madras, under the supervision of Prof. Uday Khankhoje.
