Dr. Pierre Herckes is a professor in the School of Molecular Sciences at Arizona State University, Tempe, USA. He holds a degree in Chemical Engineering from EHICS Strasbourg and M.S. and Ph.D. 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. 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 environmental analytical chemistry, developing tools to investigate the sources, occurrence, and fate of pollutants in the environment. His recent study has focused on the detection of emerging contaminants such as nitrosamines or nanomaterials in environmental and biological samples.
