Nanotribology (nano-scale friction, wear & lubrication)
Using Friction Force Microscopy (FFM), we study sliding friction at the nanoscale under various environmental conditions. Our research reveals how materials behave in different surroundings (focusing on liquid environments) and how trapped molecules influence friction dynamics. We employ advanced models to understand stick-slip behavior and energy dissipation mechanisms at the atomic scale.
Biomolecular / soft matter mechanics
We explore how protein-based materials respond to mechanical forces, with particular focus on hydrogels and self-assembling protein structures. Through micro-indentation and force spectroscopy, we investigate force relaxation mechanisms, structural hierarchies, and mechanical properties across different length scales. This research bridges fundamental understanding with potential applications in bioengineering. This research helps bridge the gap between molecular mechanisms and macroscopic material properties.
Particle-surface Interactions
We investigate how microscale particles interact with and detach from surfaces - a critical process with implications for environmental safety and public health. Our lab has developed innovative methods to measure adhesion forces and predict resuspension behavior, particularly for inhalable particles. We've developed new approaches to reconstruct adhesion force distributions from experimental measurements.
