About
Christoph Hollnagel is a pioneer in the intersection of robotics and neuroscience, specializing in the development of MRI-compatible mechatronic systems and their application to motor learning. His key research areas include fluidic actuation—both hydraulic and pneumatic—for robotic interfaces designed to operate within the strong magnetic fields of functional MRI (fMRI) scanners, as well as the neural basis of locomotion and error-based motor training. Hollnagel’s major contributions center on overcoming the actuation challenges posed by MRI environments, as demonstrated in his highly cited 2008 paper (93 citations) comparing hydrodynamic and pneumatic systems. He designed novel devices, such as a pneumatic stepper and a footplate for stepping tasks, enabling the first fMRI studies of brain activity during locomotion adaptation (60 and 19 citations). His work critically explored whether robotic therapy should minimize or encourage errors during motor learning, a fundamental question for rehabilitation. With over 200 total citations, Hollnagel’s research has provided essential tools and insights for understanding how the brain controls movement, directly informing the design of next-generation robotic rehabilitation strategies.
