    Vellore Institute of Technology - Vellore, India

    Undergraduate Researcher
    SPHINX-Net: A Lightweight Histology-Aware Framework for OSCC Detection
    Advisor: Dr. Bharanidharan N
  • Developed SPHINX-Net, a lightweight hybrid framework with histology-aware multi-view contrastive pretraining, enabling strong patch-level OSCC detection.
  • Designed a spectral-aware recalibration block that reweights channels by frequency-domain energy to target the nuclear-texture irregularity central to tumour grading.
  • Introduced a prototype-graph head that resolves ambiguous patches through mini-batch graph context while enforcing compact class geometry, without whole-slide-image graphs.
    • PortionNet: Distilling 3D Geometric Knowledge for Food Nutrition Estimation
    Advisor: Dr. Kanchan Keisham
  • Developed PortionNet, a novel cross-modal knowledge distillation framework that allows RGB models to learn 3D geometric features from point clouds during training, eliminating depth sensor requirements at inference.
  • Designed a dual-mode training strategy with a lightweight RGB-to-Geometry Adapter that learns to generate pseudo-3D features for accurate geometric reasoning from a standard RGB image.
  • Achieved state-of-the-art performance on MetaFood3D and SimpleFood45 datasets, demonstrating effective generalization.
