Dr. Hui's expertise spans a wide range of technologies, including consumer electronics, optoelectronic devices, optical imaging instruments, biomedical devices, MEMS and optical sensors, micro/nano-scale device design and prototyping.

At Exponent, Dr. Hui assists clients with resolving complex issues related to PCBA failure analysis from the board level down to the component level, electromagnetic characterization of medical devices, optical metrology, RF and optical electromagnetic safety and risk assessment. 

Dr. Hui has over 10 years of experience in the design, characterization, debugging, modeling and simulation of optoelectronic devices, optical and MEMS devices, sensors, and optical imaging systems. He also regularly performs various types of electromagnetic field evaluations for biomedical devices and consumer electronics as well as EMI and EMC assessments.

Dr. Hui has extensive experiences in designing nanophotonic and micromechanical devices with various numerical simulation tools (e.g. rigorous coupled wave analysis, COMSOL) at Harvard University and University of Pennsylvania, fabricating the devices with a suite of micro/nanofabrication techniques in Class 1000 cleanroom facilities, and characterizing their optical, electrical and mechanical properties with various optoelectronic techniques and instrumentations.

Prior to Exponent, Dr. Hui's contributions to the biomedical community includes devising novel optical imaging schemes and constructing implantable photonic devices to fulfill unmet needs especially in ophthalmology. On the optical imaging front, Dr. Hui developed his expertise in optical coherence tomography (OCT) and coherent imaging at the Wellman Center for Photomedicine at Harvard Medical School. There he devised and constructed a highly parallelized axial-ranging technique by virtue of the complex yet tractable mode space of multimode fibers, broadband semiconductor optical amplifiers, and grating-based off-axis holography techniques for spatial demodulation. He is also experienced in a host of imaging and signal processing algorithms, including compressive sensing.

Dr. Hui has substantial experiences in the intersection of ophthalmology and biomedical devices. On the implantable optical device development front, Dr. Hui played a pivotal role in devising an optical approach for facilitating intraocular pressure sensing and glaucoma management in patients with artificial corneas (keratoprothesis) at Harvard Medical School and Schepens Eye Research Institute/ Massachusetts Eye and Ear. There he integrated a fiber-optic Fabry-Perot pressure sensor directly into artificial cornea implants. He also designed and implemented a micromagnet-based fiber-optic self-alignment mechanism for rapid engagement and interrogation through an external fiber-optic probe, which was validated with animal models. Furthermore, Dr. Hui also devised and implemented the benchmarking experiments and the theoretical framework for evaluating the intrinsic optical properties and imaging performance of the Boston keratoprosthesis in accordance with the ISO 11979-2:2014 standards. Finally, Dr. Hui is also experienced with conducting clinical studies through rigorous modeling and statistical analyses. In particular, he investigated the relationship between OCT-derived optic nerve head structural parameters and the functional visual-field results in healthy and glaucoma subjects, with the goal of providing guidance for disease detection.

In addition, Dr. Hui's contributions to the broader biosensing community consist of developing wearable optical drug-sensing devices enabled by Bloch surface waves structures, and photonic crystal-based colorimetric sensor array for volatile organic compounds in the context of disease detection at University of Pennsylvania.
