Postdoctoral Research Fellowships (OCT Image Processing and Machine Learning)

The Tearney Lab at Massachusetts General Hospital, Boston, MA, United States
Employer Description

Employer Description

Guillermo (Gary) J. Tearney, M.D., Ph.D.

Tearney Lab – Wellman Center for Photomedicine

Massachusetts General Hospital

The Tearney Lab is an 80+ person multidisciplinary lab led by Guillermo (Gary) Tearney, MD, PhD. The goal of the Tearney Lab is to see every cell in the human body so that disease can be detected at its earliest stages when it can be cured.

To this end, the lab has pioneered multiple optical coherence tomography (OCT) devices that enable 3D imaging at the microscopic scale in living human patients. These technologies include multimodality OCT where OCT is combined with spectroscopy, fluorescence, and other optical techniques, ultrahigh-resolution OCT (µOCT) where the resolution is sufficiently detailed to visualize individual cells, and functional OCT that measures the function and metabolism of cells in living systems. These technologies are implemented in a variety of devices (endoscopes, catheters, capsules, implantable) that provide accessible imaging anywhere inside the body. The lab has major programs to overcome clinical diagnostic challenges in celiac disease, food allergy disorders, malnutrition, coronary artery disease, hearing loss, GI cancer, and cystic fibrosis, among others. Novel technologies are created using device development processes and tested and validated in over 15 ongoing single- and multi-center clinical studies.

To enable this broad translational research, the Tearney Lab is outfitted with:
• Robust engineering, quality, and clinical regulatory teams
• State of the art optical laboratories
• Two class 10,000 clean rooms
• Multiple rapid prototyping facilities
• Nanoscribe optical printing
• Machine learning core

Job Description

Job Description

The role will

  • Focus on advancing state-of-the-art in automated cancer detection via medical image analysis to solve challenging problems in processing, evaluating, and interpreting clinical and pre-clinical data
  • Develop a set of semi-automated and automated image processing and analysis applications, including segmentation, classification, registration, feature extraction and pattern detection.
  • The specific aim of the fellowship can be tailored to meet individual goals, which will provide an opportunity to build clinical, research, and publication experience.
  • Working closely with the technology development teams and clinical collaborators
  • Implement analysis technologies in one or more of the following organ systems: heart, lungs, brain, ears, esophagus, colon
  • Guide research questions, design studies, and monitor the execution of those studies
  • Hold regular technical meetings.
  • Publish in world-leading high impact journals
  • Deliver milestones on time
