Klaus Muller

Klaus Muller is a Clinical Professor in the Department of Clinical Medicine at the University of Copenhagen, specializing in Paediatrics with affiliation to the Capital Region of Denmark (Region Hovedstaden). His research focuses on pediatric hematopoietic stem cell transplantation and long-term outcomes in childhood cancer survivors.

His primary research domains include:

• Pediatric Hematopoietic Stem Cell Transplantation
• Graft-Versus-Host Disease mechanisms and diagnostics
• Exercise physiology during and after childhood cancer treatment
• Nutritional aspects in long-term survivors
• Biomarker discovery for transplant complications
• Metabolic syndrome in adult survivors of pediatric cancer

Professor Muller's recent work analyzes cardiorespiratory fitness trajectories, compares GvHD diagnostic frameworks (Glucksberg vs. MAGIC criteria), and investigates endothelial dysfunction biomarkers like ST2 and thrombomodulin. His research integrates clinical assessment with molecular diagnostics to improve survivorship care, with strong emphasis on exercise interventions and nutritional support during active cancer therapy. Current projects examine mucositis pathogenesis in ALL treatment protocols and motivational factors for exercise adherence in pediatric oncology.

With over 100 research outputs including 84 journal articles, his scholarly impact spans pediatric hematology-oncology, transplant medicine, and rehabilitation science, reflected in consistent Scopus citations and international collaborations.
