Professional history
Dr. Beyer was a postdoctoral fellow with A.R. Ravishankara at the National Oceanic and Atmospheric Administration (NOAA) Aeronomy Lab in Boulder Colorado. Subsequently, he was a Professor of Chemistry at Wisconsin Lutheran College in Milwaukee for 10 years. He then moved to UW-L in 2004 where he has held the positions of Professor of Chemistry, Director of the Environmental Studies Program, and Associate Dean of the College of Science and Health.
Research and publishing
My research interests involve the formation of atmospheric aerosols and clouds as governed by phase diagram thermodynamics. The conditions under which dry particles take up water (deliquescence) to become aqueous aerosols and eventually cloud droplets are my current interest. I am also interested in the conditions where water aerosols undergo the reverse process (efflorescence) to become dry particles. I am interested in these processes because the water content and phase of atmospheric particles has a significant impact on rates of reactions at the particle surface. Thus my research has focused on the main soluble components of atmospheric aerosols: ammonium sulfate, dicarboxylic acids and their salts. Experiments include modern instrumentation such as differential scanning calorimetry (DSC), humidity controlled thermogravimetric analysis (H-TGA), and FTIR spectroscopy.
