Overview
David studied biomedical engineering at Purdue University (BS '18) where he developed an interest in optical microscopy as an undergraduate research assistant in the Huang Group. After graduating, David joined the Functional Optical Imaging Lab (FOIL) at Northwestern University as a biomedical engineering graduate student (MS '20, PhD '23). At Northwestern, David focused on the development of visible-light optical coherence tomography (vis-OCT), and developed a novel extension of vis-OCT called vis-OCT fibergraphy, which enables in vivo visualization and quantification of retinal ganglion cell (RGC) axon bundles in the retina. In addition, David introduced techniques for improving noise suppression in OCT images. David joined the BIOS lab at Duke in 2023, where he focuses on research for low-cost OCT and spectroscopic OCT techniques.
