Overview
My research focuses on the application of optical technologies for non-invasive, high-resolution imaging of biological tissues. In particular, our laboratory develops optical coherence tomography (OCT), scanning laser ophthalmoscopy (SLO), light detection and ranging (LiDAR) and other optical imaging technologies for applications in the diagnosis and treatment of disease, particularly diseases of the eye. My work focuses not only on the engineering and technical development of novel imaging technologies, but also the preparation of these technologies for commercialization through clinical validation and regulatory approval.

New Directions for Ophthalmic OCT - Handhelds, Surgery, and Robotics.
Journal Article Transl Vis Sci Technol · January 2, 2025 The introduction of optical coherence tomography (OCT) in the 1990s revolutionized diagnostic ophthalmic imaging. Initially, OCT's role was primarily in the adult ambulatory ophthalmic clinics. Subsequent advances in handheld form factors, integration into ...

Journal Article J Biomed Opt · December 2024 SIGNIFICANCE: Imaging deep structures with optical coherence tomography (OCT) is difficult in highly scattering biological tissue, such as the sclera. There is a need to visualize the suprachoroidal space and choroid through the sclera to study suprachoroi ...

Journal Article Optics letters · October 2024 We demonstrate a novel, to our knowledge, approach for phase-resolved coherent 3D surface imaging that utilizes synthetic wavelength phase-based ranging and line-scan off-axis holography. Our proof-of-concept system employs an akinetic tunable laser to per ... Full text CiteRecent Grants
