Aerosol Dynamics Modeling

We are interested in understanding processes responsible for dictating new particle formation in the atmosphere and particle size distributions by integrating box and regional models with ground-based and remotely-sensed observations. Major applications of this research include the development of novel methods to estimate ultrafine particles, to better monitor air quality, and to improve aerosol parameterizations in existing regional models.
