Prof. Tearney’s research interests are focused on the development and clinical validation of non-invasive, high-resolution optical imaging methods for human disease diagnosis. Prof. Tearney’s lab was the first to perform human imaging in the coronary arteries and gastrointestinal tract in vivo with Optical Coherence Tomography (OCT), which provides cross-sectional images of tissue architectural microstructure at a resolution of 10 µm. He has also conducted many of the seminal studies validating OCT and is considered an expert on OCT image interpretation. Recently, Prof. Tearney’s lab has invented a next generation OCT technology, termed µOCT, which has a resolution of 1 µm and is capable of imaging cells and subcellular structures in the body.
