Dr Joanna Czerwińska, PhD in Biological Sciences, is a biologist and biotechnologist with a background in animal physiology and endocrinology, currently specializing in human immunology. She works as a research scientist at the Department of Dermatology, Sexually Transmitted Diseases and Clinical Immunology, University of Warmia and Mazury in Olsztyn. Her research focuses on autoimmune skin diseases, including psoriasis, morphea, and vitiligo. She investigates the role of NETosis and lymphocyte subpopulations (regulatory, memory, and γδ T cells) in chronic inflammation and immune dysregulation. Recently, she has extended her research to cutaneous squamous cell carcinoma and basal cell carcinoma, studying apoptotic signaling pathways and immune escape mechanisms. Dr Czerwińska is the first author and co-author of several peer-reviewed articles, including “The Role of the Neutrophilic Network in the Pathogenesis of Psoriasis” and “The Analysis of a Genome-Wide Association Study (GWAS) of Overweight and Obesity in Psoriasis”. She is a member of the Polish Society of Histochemists and Cytochemists. Her research aims to deepen the understanding of immune mechanisms in skin pathology and to identify novel therapeutic targets in inflammatory and neoplastic skin diseases.
