Major research interests:

His main focus is the preclinical development and evaluation of new therapeutics for lung disease. For this work he collaborates with the major pharmaceutical and biotech companies from Europe, US and Japan. Therefore, he has extensive experience with animal models of lung disease like asthma, COPD, fibrosis and lung infection. Based on these knowledge alternative in vitro and ex vivo disease models are developed e.g. using precision cut lung slice (PCLS) technique for testing lung toxicology and immune regulation. To strengthen the translational aspects of his work he is developing additional human ex vivo models like Precision Cut Liver Slices or Precision Cut Lymph Node Slices. These models are treated with disease inducing agents like bacteria, viruses, smoke, tumor cells etc. resulting in translational human disease models available for efficacy testing of new therapeutics.

His work is embedded in industrial collaborations as well as by different EU and federal research agencies. He is member of the German center of lung research (DZL) and the Excellence Cluster Rebirth as well as the DFG Priority Programme „Mast Cells – Promoters of Health and Modulators of Disease” (SPP 1394). He was active in the collaborative research network SFB587 “Immune reactions of the lung in infection and allergy” for 12 years, where the interaction of nervous system and immune reactions in asthma was the focus of research.
