Today is Steffen's last day in our group. He has been in the group since 2010 when he did his Bachelor's project. He did his Ph.D. in our group and has been with us as a Postdoc since April 2017. It has been a long and joyful journey, and we wish him all the best in his future endeavours. Tomorrow he will start his new job as Risk Manager at Energinet in Erritsø.
