I would also like to use this opportunity to thank the people from Wroclaw for welcoming me in their group: Marta, Marcin, Maciej, Lukasz and the others. Wroclaw has become my new home and I am very excited about it. Finally, my family and friends from my previous life have always been there for me and for that I am very grateful. These past few years have not been easy and it has been very helpful to know you by my side, even though we were not geographically close, so for that thank you.
