In 2008, she started PhD in Prof. Lars Zender’s group at the Helmholtz Centre for Infection Research in Braunschweig before moving with the group to University Hospital Tübingen. During her PhD work she was applying RNAi based functional genetic and genomic approaches to study liver cancer and liver regeneration. She was involved in the development of transposon based stable shRNA technology that can be used to conduct pooled shRNA screens directly in vivo. She joined the Greten lab as a Postdoc in 2014. She is currently working on the functional identification of new modulators of metastasis in colon cancer.
Dr. Charles Pallangyo
Dr. Charles Pallangyo trained as an MD at MUHAS in Daressalam (Tanzania). He then got his PhD in Florian Greten’s lab studying the role of fibroblasts in colitis and colorectal cancer. As a postdoctoral researcher he now seeks to understand the role of IL-17RA signalling in the progression of colorectal cancer.
Adele Nicolas completed her Bachelor of Science in General Biology at Notre Dame University Louaize (Lebanon) in 2012. In summer 2014 she joined the German Cancer Center (DKFZ) as a research intern at Professor Tobias Dick`s laboratory and investigated the role of mitochondrial H2O2 in mTOR signaling. In 2016 she completed her Master of Science in Clinical Molecular Biology at the University of Balamand (Lebanon). In September 2016 she joined the laboratory of Professor Florian Greten as a PhD student. Her current research focuses on the role of cancer associated fibroblasts in invasive colorectal cancer.

Hana Kunkel joined the Greten lab in 2016 and is responsible for lab management.
Kilian studied medicine at the University of Heidelberg and received his degree in 2019. During his studies, he joined the translational surgical oncology research group of Prof. Martin Schneider at the Department of General, Visceral and Transplantation Surgery at Heidelberg University Hospital. There, he studied the role of HIF-Prolyl hydroxylases in the development of colitis-associated carcinoma. Kilian joined the Greten lab in September 2019 as a PhD candidate and is currently investigating into the role of cancer-associated fibroblasts as well as deubiquitinating enzymes in colorectal cancer.
Christin Danneil is responsible for the management of the mouse colony.
Dr. Fatih Ceteci
Dr. Fatih Ceteci studied biology and obtained his MSc degree in molecular biology from Uludag University (Turkey). In 2002, he started his PhD in Ulf Rapp's group at the Institute of MSZ in Wuerzburg. During his PhD, he focused on the role of MAPK signaling in murine lung cancer. In 2008, he obtained his PhD degree and continued to work as postdoctoral research scientist in the same laboratory at the Max-Planck-Institute in Martinsried. In 2012, he moved to Owen Sansom's lab as a senior postdoctoral fellow to perform research on colorectal cancer at the Beatson Institute for Cancer Research in Glasgow (UK). In December 2015, he joined the Greten lab as a staff scientist to continue working on human colorectal cancer.
Dr. Verawan Boonsanay-Michel
Dr. Verawan Boonsanay-Michel studied molecular biology at University of Lyon (France). In 2009, she started her PhD work in Prof. Thomas Braun’s group at the Max-Planck-Institute of Heart and Lung Research in Bad Nauheim. Her project focused on epigenetic mechanisms regulating the quiescent state of muscle stem cells and chromatin-base mechanisms contributing to the distinct stem cell states. After obtaining her PhD by end of 2013, she continued as a post-doctoral researcher in the same lab.
