Newark, Ca, Us

• Experience in research consulting environment, well-versed to handle multi-tasks and new challenges, effective communication with clients and collaborators.• Building an empirical model to derive arterial oxygen saturation based on near-infrared reflectancespectroscopy (NIRS) data obtained from human subject studies.• Designed optical models of human skins and muscles to simulate diffuse light scattering in tissues, using Monte Carlo simulation techniques.• Developed a phenomenological model capturing human dynamic physiologic and optical behaviors, including blood vessel occlusion and reactive hyperemia.• Provided consulting service to a biomedical device company client for pulse oximeter design.

Cambridge, Ma, Us

• Built a new digital holographic interferometric system to detect particle-like defects in thin-film transistor LCD panels during the manufacturing process• Designed a novel digital holographic system for characterizing nanoscale 3D vibrations of seal’s whisker sensor using MATLAB, in collaboration with MIT Ocean Engineering center• Designed a real-time 3D holographic system for imaging bubbly flows, funded by Chevron. A lensless 3D imaging system was designed, which has great portability and robustness. Its application includes deep-water exploration, leakage detection. • Developed an original compressed sensing algorithm for a real-time 3D holographic imaging system applied to sub-pixel motion detection. Traditionally, finite detector-pixel size severely limits the smallest detectable movement, orders of magnitude performance improvement was achieved by the new method• Remodeled an ultra-compact camera with improved performance and picture quality for the next-generation smart-phones, through optimization between optical performance and manufacturability using Zemax interfacing with MATLAB

San Jose, Ca, Us

• Compared and characterized two reflectance pulse oximeter sensor designs for noninvasive blood-oxygen monitoring on mobile phones. Simulated reflected optical signals from finger tipsunder dual-wavelength LED-illumination using ZEMAX optical design software.• Designed a mobile-phone based thermometer. Calibrated the thermal exchange between thermopile temperature sensor and package.

Norwalk, Connecticut, Us

• Developed an improve algorithm for estimating physiological signals by analyzing images ofvascular patterns of hands for security, anti-theft, and healthcare monitoring applications.• Explored the feasibility of applying pattern extraction algorithms to noninvasive imaging based healthcare monitoring and biometric identification devices.• Drafted patent application for the above technologies.

Cambridge, Ma, Us
