Third-cycle subject: Chemistry
Predicting cloud formation in the atmosphere remains today impossible, which results in large uncertainties in many scienfific and societal applications such as forecasting precipitations/drought or calculating the climate budget. While it is well known that liquid cloud droplets form by the condensation of water on aerosol particles, only a tiny fraction of these particles (called "Cloud Condensation Nuclei" or "CCN") actually grows into clouddroplets because of key properties that remain difficult to elucidate. In particular, while the volume composition of aerosol particles has been extensively studied, characterizing their surface represents an experimental challenge, especially for individual particles, for which almost no information is available. This project will investigate this unexplored aspect of the aerosol-cloud relationship by characterizing the surface properties of micron- and sub-micron-size individual atmospheric particles and determine their role in droplet growth, using cutting edge surface characterization techniques such as Atomic Force Microscopy AFM, and Vibrational Sum Frequency Spectroscopy VSFS. By indentifying the key surface properties that set apart the CCN in the aerosol populations, the project will considerably improve the understanding of cloud formation in background and polluted environments, of rain/drought predictions, and reduce the uncertainties in the climate budget.

Target degree: Doctoral degree
Only those admitted to postgraduate education may be employed as a doctoral student. The total length of employment may not be longer than what corresponds to full-time doctoral education in four years ' time. An employed doctoral student can, to a limited extent (maximum 20%), perform certain tasks within their role, e.g. training and administration. A new position as a doctoral student is for a maximum of one year, and then the employment may be renewed for a maximum of two years at a time.
