Research Interests:

Dr. Sheng Wu is leader for research in Sensors @ PEER. These sensors are based on light-matter elastic (Mie scattering, Optical Coherence Tomography/OCT) and inelastic (absorption, RAMAN, Laser Induced Fluorescence/LIF) interactions, and on gas adsorption/desorption processes. Major projects include multiwavelength laser scattering and LIDAR, QCL MIR isotope analyzer, tunable lasers (UV-Vis-IR) and drift-free carbon polymer sensors. Sensors and techniques developed are applied to petroleum drilling and refinery, biological science and engineering.


4 US patents awarded in nonlinear optics, light scattering and remote sensing.
