Locomotion and transport of microorganisms in fluids is an essential aspect of life. Search
for food, orientation toward light, spreading of off-spring, and the formation of colonies are …

Bacteria predate plants and animals by billions of years. Today, they are the world's smallest
cells, yet they represent the bulk of the world's biomass and the main reservoir of nutrients …

Fluid dynamics plays a crucial role in many cellular processes, including the locomotion of
cells such as bacteria and spermatozoa. These organisms possess flagella, slender …

Cell motility in viscous fluids is ubiquitous and affects many biological processes, including
reproduction, infection and the marine life ecosystem. Here we review the biophysical and …

Understanding how bacteria move close to surfaces is crucial for a broad range of microbial
processes including biofilm formation, bacterial dispersion, and pathogenic infections. We …

We calculate the hydrodynamic flow field generated far from a cilium which is attached to a
surface and beats periodically. In the case of two beating cilia, hydrodynamic interactions …

The simple model of a low Reynolds number swimmer made from three spheres that are
connected by two arms is considered in its general form and analyzed. The swimming …

Sperm swimming at low Reynolds number have strong hydrodynamic interactions when
their concentration is high in vivo or near substrates in vitro. The beating tails not only propel …

Synchronization of actively oscillating organelles such as cilia and flagella facilitates self-
propulsion of cells and pumping fluid in low Reynolds number environments. To understand …

We study synchronization of an array of rotors on a substrate that are coupled by
hydrodynamic interaction. Each rotor, which is modeled by an effective rigid body, is driven …
