Experience

Postdoctoral Researcher

  • Sovereign AI and digital twin technologies for trustworthy, locally governed clinical AI in neurology and surgery.
  • Cross-modality generative AI: synthesize amyloid PET from structural MRI for burden estimation when PET is unavailable, with safeguards against false positives in healthy populations.
  • Foundation-model framework for resting-state fMRI to learn healthy brain dynamics (self-supervised), toward clinical perturbation modeling and digital twins.
  • Real-time computer vision for DaVinci robotic gynecologic surgery: detection and promptable segmentation with visibility-aware tracking under occlusion.

Graduate Research Assistant

  • Novel image processing and deep learning for amyloid PET quantification in Alzheimer's disease: accuracy, efficiency, and accessibility.
  • MRI-assisted and MRI-less DL segmentation pipelines; quantitative equivalence to FreeSurfer and robust diagnostics across multi-site cohorts.
  • Tracer characteristic-based co-registration for simultaneous PET/MR motion correction; PET biomarker (awSUVR) for MCI-to-AD progression with domain-specific anatomy and tracer modeling.
  • Large-scale stats: Centiloid calibration, equivalence testing, ROC, bootstrap; collaboration across nuclear medicine, radiology, neurology, and CS.
