INTRODUCTION
I am specialized in mid-infrared spectroscopy and its applications. My current research focuses on the detection of greenhouse gases and the determination of their impact on climate. My areas of teaching includes optics, thermodynamics, atomic and molecular physics, laser physics, atmospheric physics, astronomy and general physics.
RESEARCH
My research interest is centered on the detection of organofluorine compounds by optical spectroscopy techniques. Organofluorine compounds are anthropogenic molecules used in the industry and consumer products. Once release in the environment, they become potent greenhouse gases and contribute to climate change. My current research encompasses two different orientations:
- Experimental and computational acquisition of the spectral signatures of trace gases to determine their impact on climate.
- Detection of liquid and solid surface contaminations by attenuated total reflectance techniques.
Facilities: Dr. Le Bris Laboratory is equipped with a high resolution Nicolet™ iS50 FTIR Spectrometer, a 10-com long temperature controlled gas cell, and a single-pass ATR system.
Prospective undergraduate and graduate students: If you are interested in doing research at the interface between physics, chemistry and environmental sciences, contact me at klebris@calstatela.edu or drop by my office!
