Research Interests

To address the issue of climate change, there is a strong need to understand atmospherical processes in order to predict future changes through modeling. The ocean, covering nearly 70% of the Earth’s surface, is one of the biggest natural influences on the composition of the atmosphere. Up to date, the complex interactions with this vital component of the Earth’s system are not fully understood. Especially chemical reactions at the interface of the ocean are poorly characterized, although they potentially represent a large influence on the marine atmosphere. For example, the ocean is a net sink for ozone through the reaction with iodide at the surface of the ocean, but it remains unsure how other reactions could be involved in this ozone loss.

My research focuses currently on interfacial processes at the surface of the ocean, which are studied through laboratory studies and field observations. This englobes ozone deposition processes at the water surface, but also working towards a better understanding of the chemical and physical characteristics of the surface microlayer of the ocean. Our interest lies in the upper micrometers of the ocean, the so called ‘ocean skin’, which is quite challenging to sample and to characterize on a molecular level. By using a combination of different analytical techniques, both chemical and physical, we hope to gain more insight into the properties that reign the surface interactions between the ocean and the atmosphere.
