Dr. Stephan Harm is a Postdoctoral Researcher at the Center for Biomedical Technology, University for Continuing Education Krems (Austria). His work concentrates on apheresis and extracorporeal blood purification, with particular emphasis on adsorption-based removal of endotoxins, cytokines and uremic toxins; regional anticoagulation strategies; and blood–material interactions. Leveraging a background in biotechnology (MSc, BOKU Vienna) and a PhD in Life Sciences/Pharmacy (University of Vienna), he develops and characterizes functional sorbents, investigates antimicrobial-peptide–mediated pathogen clearance, and explores heparin–material interfaces to improve device biocompatibility. Harm has authored more than 30 peer-reviewed articles, most recently demonstrating enhanced blood compatibility of heparin-functionalized surfaces (Frontiers in Materials, 2025) and reliable endotoxin detection in serum (Scientific Reports, 2024). His patents on selective endotoxin sorbents and the award-winning “Blood Vessel Chamber” ex-vivo model foster collaboration with clinicians and industry. Recognized by the ESAO Research Prize, Krems Cooperation Award, Tecnet/Accent Innovation Award and Herbert-Stiller-Förderpreis, he strives to translate molecular insights into safe, effective blood-purification technologies and to promote interdisciplinary dialogue as Guest Editor of Biomolecules.
