This PhD project aims at better understanding the atmospheric aerosol nucleation mechanisms with chemical ionization mass spectrometry. These projects are currently supported by National Science Foundation (NSF).
Atmospheric aerosol particles affect climate, atmospheric composition, air quality, and human health. Nucleation is a gas to particle conversion process in which solid or liquid aerosol particles form directly from gas phase species, but the nucleation mechanisms are poorly understood. We will investigate how sulfuric acid, ammonia and organic compounds contribute to aerosol nucleation.
Successful candidates should have a first degree in a relevant subject (generally chemistry or physics), have a strong background in physical and analytical chemistry, and have excellent experimental and good computing skills.
PhD students will be fully supported with a stipend of $20-22K per year, either directly by NSF grants or via teaching assistantship.
