Welcome to the home page for Stephanie J. Chiu


I recently graduated from Duke University with a Ph.D. in Biomedical Engineering. Prior to graduate school, I received my B.S.E. degree in Biomedical Engineering at Duke in 2007, then spent two years at Microsoft working on Windows 7 as a Software Development Engineer in Test.

Currently at Duke, my research interests include the image processing of medical images to aid researchers in their studies of diseases. Under the advisement of Professor Sina Farsiu and co-advisors Joseph Izatt and Cynthia Toth, my focus is on the development of novel algorithms to automatically segment ophthalmic structures imaged using Optical Coherence Tomography systems.

I work in close collaboration with the Duke Eye Center so the algorithms we develop can be used in ophthalmic studies to more efficiently process clinical data. This is exciting because it gives our medical collaborators the resources necessary to analyze ocular diseases on a larger scale, bringing us one step closer towards the attainment of earlier diagnoses and ultimately better patient vision.
