I joined the ATB 2013 for my PhD as a passionate biologist interested in tumor biology and biochemistry under the supervision of Prof. Dr. Kopitz and Dr. Gebert. During my PhD I mainly focused on deciphering the contribution of glycan-binding proteins, called Galectins, on colon cancer tumorigenesis in an in vitro model system. After my graduation in 2017 I have continued working in this field as a postdoctoral researcher.
Apart from studying molecular alterations during colon carcinogenesis in humans I currently investigate molecular alterations in a mouse model for microsatellite unstable cancers. This project aims to identify potential tumors drivers that could be used for vaccination strategies in a clinical setting in the future. Both projects share the enthusiasm for basic tumor biology which represents the fundament for translating basic research into clinical application.
