Applied ML and computer vision research in histopathology and related domains, with emphasis on reproducibility and translation.

Research Projects

Whole-Slide Imaging Tools & Labeling

Built annotation and labeling tools for histopathology datasets using HistomicsTK and OpenCV to accelerate dataset creation across TB, Pap smear, and cell segmentation tasks.

  • Reduced manual annotation effort by 100+ hours per dataset
  • Integrated color deconvolution for stain separation
  • Enabled scalable patch extraction and quality control

Color Deconvolution & Preprocessing for Stained Slides

Developed robust color deconvolution, normalization, and preprocessing pipelines to improve component separation and downstream ML accuracy on stained histology slides.

  • Standardized stain variability across datasets
  • Improved signal-to-noise for cellular structures
  • Plug-and-play preprocessing modules for ML workflows

CNNs → Transformers Benchmarks

Benchmarked 20+ CNNs and Vision Transformers for Ziehl–Neelsen Mycobacteria detection, including ablations on augmentation strategies and ensemble methods.

  • Top single model: RegNetX-8GF (95.99% accuracy)
  • Best ensemble: DenseNet-169 + ResNet-34 (AUC=0.987)
  • Found light/no color augmentation often outperformed heavy schemes

LLMs for Histopathology

Evaluated GPT vs Gemini for zero-/few-shot patch classification across AFB, CRIC, and BreaKHis datasets; explored prompt design and transfer learning.

  • GPT-4.1 strongest; few-shot fine-tuning achieved 0.93 on AFB
  • Multiclass prompting improved performance on CRIC
  • AFB-tuned models transferred better to BreaKHis

Pap Smear Detection (ISBI PS3C)

End-to-end pipeline with self-supervised ViT pretraining (DINO) and advanced augmentation; competitive leaderboard performance.

  • Placed 8th of 60 global teams (F1=0.7455)
  • Strong results with DINO pretraining and tailored augments
  • Iterative error analysis to refine hard-case performance

Neuroscience: fMRI Deep Learning (Algorithmic Mind Reader)

Decoded semantic thought representations from fMRI using neural networks and genetic algorithms; built interpretability and visualization pipelines.

  • 20× better-than-random decoding accuracy
  • Correlated brain regions with cognitive functions
  • Visualization tooling for neuroscientific interpretability

Commercialization & Leadership (I-Corp & Coulter)

Completed two competitive commercialization programs, conducting 400+ stakeholder interviews and securing a $50K grant to advance translational AI in pathology.

  • 400+ structured clinician and admin interviews
  • $50K commercialization grant secured
  • Investor-grade pitch materials and market validation
