The BMS and MATH+ staff mourns the death of our student assistant Hannah Rohwer. She was studying Scientific Computing towards a master's degree at TU Berlin and had previously completed her Bachelor's degree in Mathematics at U Münster where she also worked for the cluster of excellence "Mathematik Münster". She was an incredibly kind and intelligent person who is dearly missed. We are thinking of her family and friends and everyone who knew her. Our shock and grief can hardly be put into words.
