In one of the first examples of how mechanics can inform axonemal mechanism, Machin's
study in the 1950s highlighted that observations of sperm motility cannot be explained by …

Dave Garbers' work significantly contributed to our understanding of sperm's regulated
motility, capacitation, and the acrosome reaction. These key sperm functions involve …

The deformations of flagella are important in the motility of single-and multi-flagellated
bacteria. Existing numerical methods have treated flagella as extensible filaments with a …

Spermatozoa self-propel by propagating bending waves along a predominantly active
elastic flagellum. The organized structure of the 9+ 2 axoneme is lost in the most-distal few …

Slender objects are commonplace in microscale flow problems, from soft deformable
sensors to biological filaments such as flagella and cilia. While much research has focused …

Flagellar motility is critical to natural and many forms of assisted reproduction. Rhythmic
beating and wave propagation by the flagellum propels sperm through fluid and enables …

We propose a finite element method for simulating one-dimensional solid models with finite
thickness and finite length that move and experience large deformations while immersed in …

Micro-swimmers such as spermatozoa are able to efficiently navigate through viscous fluids
that contain a sparse network of fibers or other macromolecules. We utilize the Brinkman …

There are many micro-organisms, including sperm, that move in confined geometries. With
sperm as a motivating example, we investigate emergent trajectories and beat forms of an …

Although hydrodynamic interactions and cooperative swimming of mammalian sperm are
observed, the key factors that lead to attraction or repulsion in different confined geometries …
