In this talk, I will discuss three of my recent papers entailing microscale biofluiddynamics:

1. For internal biofluiddynamics, I will discuss how cilia drive a fluid flow in a transient spheroidal cavity in the developing zebrafish embryo which is associated with the left-right patterning of internal organs. Using simple modelling, I will demonstrate how experiments might be performed to determine the mechanism through which asymmetric flow is translated to asymmetric oran placement.

2. For external biofluiddynamics, I will demonstrate that flow shear-rates calculated via PTV flow-fields around planar undulatory swimmers, in this case the nematode worm C Elegans, can be underestimated by up to 40%, and provide a simple formula for correcting this underestimate validated against numerics and experiment.

3. Finally, for artificial biofluiddynamics, I will discuss the autophoretic motion of chemically active particles at microscopic scales, and its modelling via a regularised boundary element method.
