Research Interests: 

Atmospheric physics; chemical physics.

Research: 

• Laboratory studies of the optical and chemical properties of mineral dust and carbonaceous dust aerosols
• Theoretical modeling for light scattering and absorption by aerosols
• Laboratory studies of gas phase and heterogeneous chemical processes and reaction dynamics
• Laser spectroscopy
• Two labs: Major instruments include tunable Nd:YAG-pumped OPOs, a time-of-flight mass spectrometer, aerosol generation & characterization instrumentation, FTIR and UV-vis spectrometers, an environmental simulation chamber
• Students use varied experimental techniques for aerosol characterization and chemical processing, laser scattering studies, mass-spectrometry, and spectroscopy, and also carry out theoretical modeling studies
