Postdoctoral Researcher · AI in Medical Imaging & Healthcare Data

Experience

Postdoctoral Researcher

  • AI in medical imaging & healthcare data: trustworthy, locally governed clinical AI for neurology and surgery.
  • Cross-modality generative AI: synthesize amyloid PET from structural MRI when PET is unavailable.
  • Foundation-model framework for resting-state fMRI to learn healthy brain dynamics (self-supervised).
  • Real-time computer vision for DaVinci robotic gynecologic surgery: detection and promptable segmentation with visibility-aware tracking.

Graduate Research Assistant

  • Image processing and deep learning for amyloid PET quantification in Alzheimer's disease.
  • MRI-assisted and MRI-less DL segmentation; quantitative equivalence to FreeSurfer across multi-site cohorts.
  • Tracer characteristic-based co-registration for simultaneous PET/MR motion correction.
  • Large-scale stats: Centiloid calibration, equivalence testing, ROC, bootstrap; collaboration across nuclear medicine, radiology, neurology, and CS.
