NSF Postdoctoral Fellow, University of North Carolina at Chapel Hill

I am a postdoctoral fellow working with Prof. Turpin in Environmental Sciences and Engineering at the University of North Carolina at Chapel Hill. Previously I was a postdoc in the Kreidenweis group at Colorado State University. I hold an MS and PhD in Atmospheric Science and a BS in Physics from North Carolina State University.

I study the physical and chemical properties of aerosols. Atmospheric aerosol particles (e.g., dust, smoke, vehicle exhaust, ...) interfere with earth's radiative balance, collect condensing water, and can cause respiratory and cardiovascular problems.

There are still large uncertainties in the sources, lifetime, and removal of aerosols from the atmosphere. Organic aerosols in particular have a wide range of formation mechanisms and properties.

My project is aimed at reducing these uncertainties by establishing:

(1) reaction products and volatility of secondary organic aerosol formed by aqueous oxidation, and

(2) theoretical recommendations for predicting aerosol behavior in the atmosphere.

This material is based upon work supported by the National Science Foundation under Award No. AGS1624696.
