First Lecture


Exotic Chemistry in Remote Environments - Photodissociation of Interstellar Aromatic Hydrocarbons


Jordy Bouwman (Leiden Observatory) Jordy currently employed as an assistant professor in the Sackler Laboratory for Astrochemistry at Leiden Observatory, where he conduct his research on a NWO/vidi grant. See website (http://home.strw.leidenuniv.nl/~bouwman/) for more information about his research interests.

Polycyclic aromatic hydrocarbons are very abundant in the interstellar medium and play an important role in the cosmic cycle of matter. However, little is known about their photochemistry under the exotic interstellar conditions (e.g. strong radiation fields). In this presentation I will show how we can shed light on the photodissociation of interstellar aromatic molecules by making use of synchrotron and free electron laser facilities in combination with quantum chemical computations.

Second Lecture, Lorentz Center highlight

ow do microbes adapt to changing conditions?

Bob Planqué (VU Amsterdam) Bob is an assistant professor in Mathematical Biology in the Mathematics Department at the Free University. See his website for more information about his research interests. http://www.few.vu.nl/~rplanque/index.html Bob is one of the organizers of the workshop “Principles of Microbial Adaptation” that is being held in the Lorentz Center from 5 Mar through 9 Mar 2018.

Microbes live in a world that constantly changes. Even if nutrient concentrations remain the same, they still continuously grow and divide, making themselves completely anew, often at breathtaking speed. In this short talk, I will highlight a new theory how microbial cells are able to cope with such situations, and will illustrate it with recent data on individual dividing cells.
