Research, Collaborations and Field Leadership
From generative image restoration to hyperspectral sensing, my projects combine representation learning with real-world data and interdisciplinary collaboration.
Current Research Directions
Hyperspectral Gaussian Splatting
Exploring Gaussian representations for hyperspectral denoising and reconstruction, including spectral bases and residual restoration strategies.
DenoisingSpectral Basis
Implicit HSI Super-Resolution
Adapting implicit neural representations to continuous hyperspectral reconstruction so that spatial queries can recover spectrally consistent high-resolution signals.
LIIFNeural Field
Generative Restoration
Developing latent-space and training-free approaches for difficult real-world image degradations, with emphasis on robustness and faithful reconstruction.

Collaborations & Field Work
3D Geophysical Image Translation using GANs
Feb 2024 — Jan 2025
A year-long collaboration with geoscientists, translating 3D geophysical scans into photorealistic virtual outcrop geology.
What this involved
Interdisciplinary problem formulation, generative modelling and communication between geological interpretation and computer-vision representations.
Smart Farming of Cotton using Aerial Imagery — COT-AD
Jun 2023 — Jan 2024
Designed and ran a six-month acquisition campaign with agricultural researchers, flying weekly missions at 10 m, 15 m and 115 m. I owned the flight schedule, the multi-altitude protocol, and the dataset that became COT-AD.
Why the dataset matters
The repeated multi-altitude observations follow the same field across a full cotton growth cycle, connecting acquisition strategy with downstream visual analysis.
Drone and Core Data Acquisition — Earth Science, IIT Gandhinagar
2023 — 2024
Planned and led three multi-day campaigns for aerial and core sample collection. Site names withheld for confidentiality.
3D Vision Summer School — IIIT Bangalore
Jun 2024
Week-long school on deep learning for 3D vision. The Gaussian splatting sessions shaped the direction my hyperspectral work took afterwards.
Visvesvaraya PhD Scheme Workshop — IIT Mandi
May 2024
Presented my work to an interdisciplinary audience of scholars from across engineering disciplines.
