Description
Interactions between micro-swimmers and solid boundaries play an important role in many biological
and technological processes. I will discuss our ongoing work in modeling and simulations that aim to understand the
motion of micro-swimmers such as bacteria, micro-algae, spermatozoa or active colloids in various confinements or
in structured environments. Our results highlight a complex interplay of the hydrodynamic and contact interactions of
the individuals with each-other and the boundaries to give rise to non-trivial individual and collective behavior.
