Abstract:
Laser spectroscopy plays a significant role over a wide range of applications such as combustion and propulsion, environmental monitoring, and biomedical research. In combustion diagnostics and petroleum industries, sensors are installed to monitor key species in processes to understand combustion fundamentals, or to ensure safety and efficiency. Ultra-sensitive and reliable trace gas sensors are required in environmental science to measure greenhouse gases and air pollution, as well as in biomedical research to identify biomarkers related to particular diseases and metabolic disorders. Of various gas sensing strategies, laser absorption spectroscopy provides opportunities with species-specific, non-intrusive, and quantitative measurements of gas molecules. This talk will focus on recent advances in semiconductor laser-based spectroscopy for energy and environmental applications.

Dr. Wei Ren is currently an assistant professor in the Department of Mechanical and Automation Engineering at the Chinese University of Hong Kong. He received his B.S. and M.S. both from the Department of Precision Instrument at Tsinghua University in 2006 and 2008, respectively. He obtained his Ph.D. degree in Mechanical Engineering from Stanford University in 2013. After his graduate work, Dr. Ren was awarded a Robert A. Welch Foundation Postdoctoral Fellowship to join the Laser Science Group at Rice University, where his research focused on trace gas sensing for environmental monitoring, industrial process control, and biomedical applications. His current research interests focus primarily on combustion and propulsion, optical diagnostics and sensors, alternative fuels, and environmental research. Dr. Ren is a Member of Combustion Institute (CI), the Optical Society (OSA), and Society of Photo-Optical Instrumentation Engineers (SPIE).
