Electrical & Computer Engineering
Purdue University
I am a PhD researcher in Electrical & Computer Engineering at Purdue University, working at the intersection of condensed matter physics and high-performance scientific computing. My dissertation, Phase Field Modelling of Quantum Metamaterials, is supervised by Prof. Pramey Upadhyaya.
I combine analytical models with Julia simulations to study magnetic order and ferroelectric polarization. Before Purdue, I designed satellite electronics at ISRO and established a semiconductor device characterization lab.
More about my background
I study how currents control noncollinear magnetic order in Mn₃Pt-type chiral antiferromagnets. Analytical models and numerical simulations reveal spin dynamics, switching paths, and the effects of current-induced torques.
Explore selected work
I develop phase-field simulations to study how polarization textures evolve and respond to excitation in STO/PTO ferroelectric structures. Spectral numerical methods couple polarization dynamics with electrostatics.
Simulation tools
I explore physics-informed neural networks and neural operators for model discovery and surrogate modeling of dynamical systems, using physical constraints to guide learning from data.
Read the paper
I use micromagnetic simulations to study how twisting magnetic layers changes their spin textures, investigating noncollinear magnetic phases and domain walls in moiré materials.
Read the preprintDirect density-of-states mapping probes size-dependent localization in oxide semiconductors.
Lock-in electric-field penetration is used to map the effective density of states in In-based oxide semiconductor TFTs, showing that band-tail states become screening- and transport-active. Geometry-dependent DOS mapping reveals exponential suppression of the effective DOS with channel length — a microscopic origin of localization-induced threshold-voltage roll-off — and that disorder can be tuned via thickness, O₂ annealing, and In/Ga/Zn composition.
Twisting magnetic layers produces noncollinear spin textures and 90° domain walls.
Twisted CrCl₃ XY magnets host robust noncollinear moiré magnetism, with field-driven transitions from coexisting AFM and FM domains that persist up to double nine-layer stacks. Combined with micromagnetic simulations, the ground state is identified as the predicted “twisted-s” phase with 90° domain walls, and these phases are shown to be electrically tunable.
Short-time Fourier synthesis addresses spectral bias in physics-informed viscoelastic modeling.
Spectral bias — the tendency of neural networks to learn low-frequency components while missing high-frequency transients — limits PINNs for viscoelastic characterization of pavement geomaterials under time-varying loading. We developed a spectral temporal synthesis framework using inverse Short-Time Fourier Transform (iSTFT) operations, with learnable complex-valued spectral–temporal representations, to enable physics-informed learning of viscoelastic operators across millisecond-to-second timescales.
