🚀 What I Do

I build deep learning systems that detect cancer from tissue slides, segment organs from 3D MRI, and decode brain signals — with results that beat published state-of-the-art benchmarks. I also design adversarial CS tasks that expose where frontier LLMs fail, bridging research and model evaluation.

LLM Benchmarking Work

→ llm-cs-eval-tasks — 15 real systems engineering tasks that expose LLM reasoning failures

I design and evaluate complex CS debugging tasks as part of active LLM benchmarking work. These tasks cover:

  • Protocol bugs requiring RFC-level spec knowledge (DNSSEC, HTTP/2, UART)
  • Systems debugging with no documentation — format must be reverse-engineered from binaries (WAL, eBPF, custom ISA)
  • Multi-layer cascade failures where fixing layer A reveals bugs in B, C, D
  • Custom codecs, embedded linker scripts, distributed tracing pipelines

Failure patterns I document: cascade reasoning, spec inference, simultaneous multi-layer repair, byte-identical precision, edge-case semantics

🧠 Active Research

🦷 Oral Cancer Detection — NIT Jamshedpur (Dec 2025 – Present)

  • Designing a DWT-Gabor Fusion Swin Transformer for early-stage OSCC classification from H&E-stained histopathological images
  • Novel 4th-channel input strategy: fusing multi-level Haar DWT + Gabor filter energy maps → stain-invariant frequency-domain features (cell boundaries, nuclear texture, tissue architecture)
  • Replacing standard ViT patch merging with DWT-based patch merging — preserves edge and texture information critical for fine morphological distinction
  • Benchmarking on NDB-UFES dataset (237 images, 3 classes) · correcting data leakage in prior work · 5-fold stratified image-level CV

🧬 DCFNet: 3D Liver Segmentation — Master's Thesis

  • Dual-encoder architecture with Cross-Attention Fusion Module (CAFM): bidirectional cross-attention + learned per-voxel spatial gating
  • Extended Coordinate Attention from 2D → 3D for volumetric medical image analysis
  • Pipeline: PyTorch + MONAI · boundary-aware loss · deep supervision · mixed-precision · single NVIDIA T4 GPU
  • Evaluated on 318 3D MRI volumes (CirrMRI600+) · 4 baselines · 6-variant ablation study · statistical significance testing
