Ulrich auf dem Keller – a friend, a mentor, a visionary line manager, a fantastic scientist, a wonderful husbamd and father – has sadly and suddenely passed away last August 2023. His death has left all of us in shock. We are thinking about his family, friends and community. We will all miss him in the years to come and we will try to honour his legacy in the best way possible. Thank you Ulrich for everything that you ahve done for me.
