Program Co-Chair

Prof. Choa received his B. S. degree from National Taiwan University, and his M. S. and Ph. D. degrees from SUNY at Buffalo. After his Ph. D. work on femtosecond long-wavelength near infrared lasers in 1988 he joined AT&T Bell Labs at Holmdel and Murray Hill, NJ and worked in the area of photonic integrated circuits and chemical beam epitaxy. Since joining UMBC in 1991, he has been working in the areas of III-V compound semiconductor material growth & processing, broadband WDM switches and networks, RF-photonic components and systems, quantum cascade lasers, photon counting avalanche photodiodes and arrays, photoacoustic sensing, imaging, and acoustic array signal transmissions-receiving, photoacoustic aerial- undersea communications, silicon photonic integrations, bio-inspired nanostructures, and meta-materials – devices, EEG, fMRI brain imaging analysis and brain stimulations. Since 1991, Prof. Choa has sponsored and co-sponsored with a total of more than $20 million in research funding from different sources, including MOCVD crystal growth facility built at UMBC. He has authored and co-authored more than 430 refereed publications. He is a Fellow of Optica (OSA) and a fellow of SPIE. He has served as Topical Editor of Optics Letters, Associate Editor of the Journal of High Speed Networks, and Editorial Board of the Journal: Sensors.
