Cheng-Sheng Huang received his Ph.D. in Mechanical Engineering from the University of Washington, Seattle, in 2009. He then served as a postdoctoral research associate in the Department of Electrical and Computer Engineering at the University of Illinois at Urbana-Champaign. He is currently a professor in the Department of Mechanical Engineering at National Yang Ming Chiao Tung University, Taiwan. His research interests include micro/nanofabrication, micro/nanodevices, sensors and biosensors, and microspectrometers, with a focus on optical transducers.

Biosensing can be broadly categorized into two types: label-based sensing and label-free (LF) sensing. Fluorescent detection is the most common technique for label-based biosensing. In contrast, LF biosensors based on various optical mechanisms remain highly competitive due to their exceptional sensitivity, immunity to electromagnetic interference, capability for remote sensing, real-time monitoring, and simple setup configuration, among other advantages.

For both fluorescence and optical LF detection in many biosensing applications, spectrometers play a crucial role in spectral detection and characterization of reflection, emission, and absorption spectra.

At the Micro/Nano Sensors Lab, our research focuses on biosensing with several key directions, including optical biosensors, compact spectrometers, integration of label-free biosensors with microfluidics, smartphone and handheld biosensor systems, and photonic crystal-enhanced fluorescence.
