The overall goal with our research is to study the pathogenic mechanisms leading to lymphoma and autoimmunity, and factors controlling disease progression. The ultimate aim is to improve diagnosis, monitoring the disease and improving treatment of these patients. 

Our laboratory at the Centre for Molecular Medicine (CMM) is strategically placed close to the Karolinska University hospital, enabling easy access of clinical samples. We use a broad array of advanced laboratory techniques, including in vitroand ex vivoassays of cellular immunology, cell biology and genetic analysis, to investigate unique clinical material and perform registry studies.We have a strong collaborative team with clinicians and researchers in dermatology, rheumatology, hematology, pathology, immunology and epidemiology. 

The research is clearly translational, bridging from patients to basic science and back to the patients again, with the scientific questions always originating in the clinical disease. 


We are always looking for highly motivated people to join our team. Please contact Hanna Brauner if you are interested, at hanna.brauner@ki.se



Hanna Brauner

I am currently researcher and team leader at Centre for Molecular Medicine (CMM), the Department of Medicine, Solna and physician at the Dermatology clinic, Karolinska University hospital. I defended my thesis in 2010, at the Department of Microbiology, Tumor and Cell biology, Karolinska Institutet (KI), supervised by professors Petter Höglund and Klas Kärre. My first postdoctoral training was with professor James Di Santo, the Pasteur Institute, in 2012-2013. Thereafter I did a second postdoctoral period with associate professor Lisa Westerberg, KI, in 2015-2017. In 2018 I was awarded a young investigator award from the Swedish Society for Medical Research (SSMF) and was recruited to the Department of Medicine, Solna and CMM to continue to develop my research within the field of autoimmunity and lymphoma.
