The nature of Dr. Wang’s research is multidisciplinary, involving physics, chemistry, and optical engineering. His research interest is to develop and apply measuring, monitoring, and sensing technologies to address real problems in energy, environment, and biomedical engineering. He believes that one powerful technology, CRDS, can have unlimited application potential in the aforementioned fields and beyond. Currently, Wang group’s research efforts are dedicated to

1. Laser diagnostics in plasma and combustion, especially, plasma-assisted combustion (PAC). 
2. Time-domain fiber optic sensor and sensor network for large-scale, multi-function (physical, chemical, and biological) monitoring and sensing. Time-domain fiber optic sensor and sensor network for large-scale, multi-function (physical, chemical, and biological) monitoring and sensing. 
3. Cavity ringdown instrumentation for trace elements, isotopes, and volatile organic compounds. 
4. Breath biomarkers for non-invasive disease diagnostics and metabolic status monitoring.
5. Physical and chemcial study of single aerosol particles optically trapped in air.
