Research Interests

Most of our research deals with the question how cell stress pathways, inflammation and redox biology impact on each other and how these systems contribute to human diseases. In particular, we are interested in cardiovascular diseases (thrombosis; atherosclerosis), tumour biology (cell death resistance; angiogenesis) and finally in inflammatory signalling of host cells in response to bacterial virulence factors. Our mission is to understand key cellular signalling events of clinical relevance. To this end, our projects use material ranging from cell cultures to mice and human samples. We cover a broad range of techniques and have several local as well as international collaborations.

Key techniques: Confocal imaging, FACS, qRT-PCR, redox biology, gene expression studies, vascular biology

Research system/organism: Human cell systems and specimen; mice
