Cheng-Hao Ko received his Ph.D. and M.S. degrees in physics from the State University of New York at Stony Brook in 1995 and 1990, respectively. He received his B.S. in physics from National Taiwan University in 1985. His doctoral research was on x-ray microscopy combined with electron spectroscopy for chemical analysis.

After receiving his Ph.D., he joined the National Synchrotron Radiation Research Center of Taiwan as an associate research scientist. He led a team to design and construct the first scanning photoemission microscope in Asia. He is currently an associate professor at National Taiwan University of Science and Technology. His current research areas are SpectroChip, hyperspectral imaging, linear variable filter, and MEMS biosensors.

He serves as the executive director of Taiwan Society of Optical Design. His outstanding works on micro-spectrometer has won the Eleventh (2008) Outstanding Photonic Product Award, Nineteenth (2012) Ministry of Economy SME Innovation Research Award, and Second (2012) National Industrial Innovation Award. Dr. Ko founded SpectroChip, Inc. in 2012 to establish the technology development of SpectroChip. He is currently applying the SpectroChip technology for home healthcare and food safety inspections.
