- Developed a surgical planning tool for LRI procedures. Interfaced with an external party’s simulation to determine optimum incision locations, produces a surgical plan featuring appropriate blades and diagrams. - Key role in commercializing Eye Check, an acquired phone-based medical device that detects numerous ocular features (e.g. focal deviation, pupil eccentricity, measures of symmetry). Additionally, currently extracting its feature detection algorithm to support assessing its quality for future investment independent of medical device’s limitations.
