Research Description

Our group is interested in how light interacts with molecules and small particles that are important in Earth’s atmosphere.  We use lasers to make precision measurements using photoacoustic spectroscopy and/or cavity ring-down spectroscopy.  Typical systems of interest include greenhouse gases, remote sensing molecules, and small carbonaceous aerosol particles.  Students learn valuable skills in optical spectroscopy, line shape theory, laboratory automation, electronics, and lasers.
