Our Team

Johannes Brägelmann, Group Leader

Johannes Brägelmann

Reserach Group Leader

Physician & biostatistician by training, scientist at heart. Enthusiastic about data-driven molecular biology, machine learning and preclinical model systems to answer translational cancer research questions with the goal of improving cancer therapy. Enjoys elegant solutions to complex problems, mountaineering and music.


Mareike Haarmann

PhD student

Mareike is working as a PhD student in the lab. She is interested in understanding the processes determining treatment resistance and inflammatory signalling in squamous cell cancers of the respiratory tract on a molecular and genetic level.


Katharina Winkels

Master student

Katharina is a student at the RWTH Aachen and is currently pursuing her Master's thesis  investigating innate immune signaling pathways in small cel lung cancer in the lab (co-supervised with Prof. Martin Sos).

Alessia 3_lowres.jpg

Alessia Pantani

MD student

Alessia is a medical student at the Faculty of Medicine at the University of Cologne. Currently, she is working on her doctoral thesis in our lab. Her main interest lies in better understanding of genetical modifications in tumor cells, their metabolic and immunological outputs and therefore the possible impact on personalized oncological therapy.


Doris Helbig

Associated Research Fellow

Doris is a senior physician at the Department of Dermatology and head of the Dermatopathology lab and Biobank. Her research is focussed on genetic and tumor micro-environmental factors of cutaneous squamous cell carcinomas and sarcomas that impact treatment outcome as well as resistance. This combined approach discovers new aspects of tumor evolution, predictive biomarkers and therapeutic target structures improving individual patient care.


Carina Lorenz

Undergraduate research fellow

Carina is presently a medical student at University of Cologne. She is interested at combining genomics, transcriptomics and image analysis  to understand the tumor microenvironment and cancer evolution.


Corinna Bürger

MD student

Corinna is currently working on her MD thesis assessing the ability of deep learning to predict clinical features and disease progression in patients with squamous cell carcinoma.

Philipp Baedeker

MD student

Philipp is currently a student of medicine at the University of Cologne. He is particularly interested in pathways of the cellular immune repsonse and the opportunities they hold for future cancer therapy. In his doctoral thesis he works on better understanding the responses of squamous cell carcinoma cells to agonists of nucleic acid sensing pathways.

Joëlle Dimmler

Bachelor student

Joëlle is a student at the University of Applied Sciences Bonn-Rhein-Sieg. She is currently analyzing cell cycle processes and effects of cell cycle inhibitors in non-small cell lung cancer cells while pursuing her bachelor thesis in our lab.
