PD Dr Matthias Matter is a surgical pathologist at University Hospital Basel, providing his knowledge of immunology and molecular analysis in the frame of the BRCCH-funded “Lessons From the Deceased to the Living and Back” project. Dr Matter studied medicine at the University of Bern, where he also received an MD-PhD in the field of tumour immunology and host-viral interactions. His research experience was further extended by a postdoctoral fellowship on tumour immunology at the National Institute of Health (NIH) in Bethesda, USA. He is a surgical pathologist with a sub-specialization in molecular pathology and works at the Institute of Medical Genetics and Pathology at University Hospital Basel with a main focus on molecular pathology and gastrointestinal pathology. His main research interests are immune responses against tumours and the role of chronic inflammation, such as that caused by hepatitis B or C virus, in tumour development. In the BRCCH FTC project (link below), Dr Matter is mainly involved in study design, histopathological examination and analysis of the immune response against SARS-Cov2 in the lungs and lymph nodes using gene expression analysis and CODEX.
