Stefan Karpitschka

Dr. Stefan Karpitschka serves as a Senior Researcher and Research Group Leader at the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) in Göttingen, Germany, within the Dynamics of Complex Fluids department. His group investigates fluid behavior at solid-gas interfaces, with applications spanning everyday phenomena (ink on paper), biology (cyanobacteria motility), and semiconductor manufacturing. Affiliated with the Max Planck-University of Twente Center for Complex Fluid Dynamics, he also participates in the Priority Program SPP 2171 on dynamic wetting of adaptive surfaces.

His research focuses on interfacial phenomena in complex fluids, particularly wetting dynamics, Marangoni effects, and fluid-structure interactions. Key discoveries include the 'boomerang effect' where droplets spread and self-contract without residue (enabling chip cleaning), phase separation's role in wetting dynamics (PNAS 2022), and the 'memory of folds' in soft materials where unfolding leaves scar-based nucleation points. His work bridges fundamental physics with practical applications in microfluidics, printing technology, and biological systems.

Analysis of his 15 most recent publications reveals dominant themes in soft matter deformation (60%), active matter systems (25%), and biological fluid dynamics (15%). Key methodological approaches include high-precision force measurements, theoretical modeling of viscoelastic substrates, and experimental quantification of microbial locomotion forces.

Scientific recognition includes:

• Robert-Wichard-Pohl-Medal for 'Physics of Sports' teaching (2022)
• Alexander von Humboldt Foundation research fellowship (2022)

Dr. Karpitschka advises doctoral and master's students, with recent theses on wetting dynamics (Jeon H., 2022) and biofilm analysis (Schwirz T., 2018). His group collaborates extensively through the Max Planck-University of Twente Center and participates in the SPP 2171 coordination board. Current projects explore liquid-liquid phase separation effects, cyanobacteria gliding mechanics, and programmable folding in soft materials.

The group maintains active laboratory facilities for microfluidics experimentation, force measurement, and biological interface studies, with recent public engagement including a Science Night exhibition on cyanobacteria at the MPI for Solar System Research.
