Summer School on "Birational Automorphisms of Varieties of General Type"
Organisers: Daniel Greb, Stefan Kebekus, and Alex Küronya. The school discussed the recent results of Hacon, McKernan, and Xu on the finiteness of birational automorphisms of varieties of general type.
Research focus Quantum Efficiency
In Freiburg I participated in the interdisciplinary research focus Quantum Efficiency of the Institute of Physics. The main link between my research and this project is the use of (geometric) invariant theory in the study of entanglement.
