Tobias is a PhD student in the laboratory of Professor Walter E. Aulitzky at the Dr Margarete Fischer-Bosch Institute for Clinical Pharmacology, Stuttgart, investigating protein biology from the N- to the C-terminus and back again. Ine is a Master's student in the laboratory of Professor Thomas Arnesen at the University of Bergen, Institute of Biological Science. Emilie is a Master's student in the laboratory of Nadra J. Nilsen at NTNU Department of Clinical and Molecular Medicine in Trondheim, investigating the dual role of immune cells in cancer.
