Molecular spectroscopy: from Lab to atmosphere

Remote sensing is a powerful tool to study Earth or planetary atmospheres. The methods used to retrieve the physical and chemical properties of an atmosphere are based on the computation of the radiative transfer of the studied atmosphere. Many parameters are needed to accurately compute the radiative transfer, among them spectroscopic parameters. These parameters are of major importance, especially in the infrared spectral region. Over years, researchers have built large databases for the main atmospheric species. Spectroscopic parameters can be experimentally measured or calculated from theoretical models. The recent improvement of on-board or ground-based instruments used for remote sensing have pushed the needs for high accuracy line shape information. This presentation will give a sense of how laboratory measurements and theoretical calculations can work together to provide high-precision line shape parameters for the remote sensing community.

Ant symbionts: cryptic communities to study ecological network dynamics

A fascinatingly diverse community of arthropods ranging from parasites to cooperating mutualists, that strictly live in ant nests. Here, I will give a short overview about how I study these communities of directly and indirectly interacting symbionts to address fundamental dynamics in ecological networks and communities.

This is the last Lunch seminar this academic year, we will start again in September, on site and with sandwiches!!
