Johannes Preiner

Johannes Preiner is a University Lecturer at the Johannes Kepler University Linz (since 2014), affiliated with the NASAN - Nano Structuring and Bio-Analytics research group within the Linz Center of Excellence for Medical Engineering. His work focuses on molecular dynamics at membrane interfaces, leveraging advanced atomic force microscopy (AFM) techniques. He holds a Habilitation in Biophysics (2023) and a PhD in AFM-based biophysics (2008), with a Technical Physics background (2005).

Key research interests include antibody-mediated immune activation mechanisms, complement pathway dynamics, and membrane protein interactions. Notable collaborations include projects with GENMAB and Prof. Suzan Rooijakkers, yielding insights into IgG oligomerization-driven complement activation. Recent funded projects include IgGMedCompAct (2021–2024) and FcRClu (2020–2025).

He has received the Macke-Scholarship and contributed to over 70 publications, including high-impact work on antibody dynamics and complement activation. His presentations span international venues, emphasizing multivalent interactions in immune responses.
