​Research Interests

Interdisciplinary collaborations between biomedical and engineering professionals is one of the keys for recent tremendous creations and advancements in biomedical technologies, which also applies to the field of ophthalmology. The members of Ocular Bioengineering Laboratory are now working closely with the clinicians to engineer novel solutions to facilitate advanced biomedical research, as well as diagnosis and treatments of eye diseases. The current focuses are on developing (1) “Eye-on-a-chip” microfluidic platforms to study degeneration of retinal cells, and (2) medical devices for treatments and diagnosis of eye diseases, which includes but not limited to contact lens-based device for corneal diseases, and intraoperative tools (silicone oil, perfluorocarbon liquids) for vitreoretinal surgery.
