Biography: 

Pierre Herckes is a professor in the School of Molecular Sciences and an affiliate professor in the School of Earth and Space Exploration. His research interests are in Atmospheric Chemistry, especially aerosols and clouds as well as aerosol cloud interactions and their impact on air quality and climate. Substantial parts of his research are applied projects to address actual air pollution issues. A second research focus is on analytical chemistry, developing tools to investigate the sources, occurrence and fate of pollutants in the environment. Recent work has focused on the detection of emerging contaminants such as nitrosamines or nanomaterials in environmental and biological samples. Here too a substantial effort is aimed at applied projects relating to water quality and human exposure.

Dr. Herckes has a degree in Chemical Engineering from EHICS Strasbourg and MS and PhD degrees in Environmental Physical Chemistry from Strasbourg University (France). Before joining the faculty at ASU, Dr. Herckes was a postdoc and research scientist in the Atmospheric Science Department at Colorado State University.
