Colorectcal cancer research 

I studied medicine between 2006-2012 at the University of Regensburg and at the University of Leipzig and did my MD-Thesis (Dr. med.) on the genetic background of chronic pancreatitis in the lab of Prof. Jonas Rosendahl at the University of Leipzig. In 2013, I started my residency as a clinical pathologist at the Institute of Pathology of the University of Heidelberg (Director: Prof. Dr. P. Schirmacher) and joined the lab of Prof. Wilko Weichert. Moving to the Institute of Pathology of the Technical University of Munich (Director: Prof. Dr. W. Weichert) in 2015, I finished my Habilitation in 2018 (Privatdozent/Associate Professor) and received my board certification as a full pathologist in 2019. In November 2017, I accepted the kind offer of Prof. Saur to associate my research to his lab as a postdoctoral researcher.

Short description of research field/project:
My principal research interest is the genetic background of colorectal neoplasias and especially colorectal cancer (CRC) and its specific morphologic subtypes, which I investigated using a morphomolecular approach in the lab of Prof. Weichert.

My current research in the Saur lab focuses on organoids as a tool to comparatively model colorectal neoplasias, with a focus on factors that influence the progression from various pre-malignant precursor lesions (adenomas) to invasive carcinoma or on the potential molecular background of specific CRC subtypes, such as mixed adenoneuroendocrine carcinoma or neuroendocrine carcinoma. My research is supported by the Else Kröner Fresenius Stiftung.
