Where Materials Science, Physics & AI Meet

My research does not place one discipline above another. Physics provides the governing laws — piezoelectricity, quantum mechanics, condensed matter. Materials science provides the tangible medium — PVDF nanocomposites, perovskites, polymer laminates, 2D nanosheets. AI connects them — reading physical signals, predicting material properties, and designing new compounds. The loop runs in both directions, and it is grounded in 32 peer-reviewed papers across these three worlds.

Physics & Materials → AI
Piezoelectric polymer physics as a living dataset for deep learning — PVDF nanomaterials whose phase-transition physics encodes features no synthetic dataset can replicate.
Triboelectric surface-potential physics as the physical prior for voice recognition AI — contact electrification laws, not labelled audio data, govern what the model learns.
Quantum entanglement structure as a feature map for machine learning — using the Hilbert space geometry of quantum mechanics to separate classes that classical kernels cannot.

Building the Physics × AI Future

I believe the most important scientific breakthroughs of this decade will emerge where quantum intuition meets machine intelligence — where a researcher understands a Hamiltonian as deeply as they understand a loss function, and where a sensor is both a physical object and a living dataset.

Teaching Physics Through AI

Courses where students derive Maxwell's equations on Tuesday and train a physics-informed neural network on Thursday. Quantum mechanics labs that produce ML-ready datasets. Statistical mechanics problems that run on real hardware.

The Autonomous Materials Lab

A self-driving laboratory where ML interatomic potentials guide robotic synthesis, generative models propose quantum materials at 3 AM, and every experiment closes a loop between theory, computation, and physical reality.

The Next Generation of Researchers

Students who write Hamiltonians and train transformers in the same afternoon — who understand why a diffusion model works by analogy to a Langevin equation, who go from DFT to deployment without losing physical intuition.

Open Collaborative Science

Extending partnerships across UCLouvain, University of Bordeaux, and IISER into an open network for physics-AI benchmarks, shared self-driving infrastructure, and reproducible quantum materials datasets.

I am a Postdoctoral Research Scientist at UCLouvain, Belgium, working at the convergence of condensed matter physics, functional nanomaterials, and artificial intelligence. My current work deploys generative AI — VAEs, Diffusion Models, and multimodal networks — for the inverse design of quantum and functional materials, resulting in the MEIDNet framework published in npj Computational Materials (2026).

My roots span both materials synthesis and physics theory. During my Ph.D. at INST-IISER Mohali, I engineered piezoelectric PVDF nanocomposites, lead-free perovskite hybrids (Cs₃Bi₂I₉), and triboelectric polymer laminates — then fused deep learning directly onto these physical systems to create self-powered sensors capable of recognising voice (Small, 70 citations), tracking cardiovascular health (Adv. Mater. Technol., 32 citations), and classifying movement disorder (Adv. Mater. Technol., 34 citations).

As a Raman-Charpak Fellow at IMS, University of Bordeaux, I extended this materials-AI loop to thin-film polymer acoustics: voiceprint biometrics from a programmable PVDF interface (Adv. Mater. Technol., Journal Cover, 24 citations), an e-skin respirometer built on flexoelectric nanofibre physics (Adv. Sensor Res.), and an emotion sensor exploiting multimodal piezoresistive response (Adv. Intell. Syst.). My Quantum ML work shows entanglement-enhanced kernels outperforming classical SVMs on structured materials datasets (APL Quantum, 2025).

I serve on the Editorial Advisory Board of APL Machine Learning, as Guest Editor for Nanotechnology (IOP), and as Student Ambassador of APS — bridging the materials, physics, and AI communities from the inside.

Teaching & Mentorship Philosophy

I believe physics intuition is the most durable foundation for AI literacy. My teaching connects the two — students learn why a variational autoencoder minimises free energy before they tune its hyperparameters, and why a quantum kernel can see structure that a classical SVM cannot. Science is most alive when it is both deep and useful.
