There is quite a lot planned for this retreat. We have nine talks, including presentations by our students Peik and Karina. Jacqueline joined our group in August 2025 and will present her projects on light pollution and the use of harmonic radar. Following several field trips at the end of last year, we have a lot of data from Texas and South Africa to discuss. Last but not least, we will take a look at the progress of the renovations in our lab in Oldenburg.
