Eliisa Kekäläinen, M.D. Ph.D., research group is based at the University of Helsinki, and is part of Translational Immunology Research Program. Eliisa Kekäläinen has wide interest in immunodeficiency diagnostics and immunological tolerance. Her research focuses especially on the primary immunological organ the thymus. She is interested in how e.g. common viral infections and hematopoietic stem cell transplantation affect thymus function, how they could better measure thymopoiesis in clinical situations, and what kind of pathological processes in the thymus lead to immunodysregulation in autoimmune diseases such as myasthenia gravis. Eliisa Kekäläinen works also at the HUS Diagnostic Center Clinical Microbiology and Immunology (Helsinki University Hospital) where she mainly focuses on immunodeficiency laboratory diagnostics.

Liv Eidsmo is a board certified dermatologist, a Professor of Translational Skin Immunology and the Executive Director of the LEO Foundation Skin Immunology Research Center at the University of Copenhagen. Eidsmo graduated from Karolinska Institutet, Sweden. Following a postdoc in Frank Carbone’s laboratory at Melbourne University in Australia, her first laboratory was established at the Center for Molecular Medicine (CMM) at Karolinska Institutet in parallel to clinical training in dermatology at Karolinska University Hospital. The current laboratory at University of Copenhagen focuses on how T cells residing in the skin drive local recurrence of diseases such as psoriasis and vitiligo.  https://sic.ku.dk/research/translational-skin-immunology/
