We illustrate shape mode analysis as a simple, yet powerful technique to concisely describe complex biological shapes and their dynamics. We characterize undulatory bending waves of beating flagella and reconstruct a limit cycle of flagellar oscillations, paying particular attention to the periodicity of angular data. As a second example, we analyze non-convex boundary outlines of gliding flatworms, which allows us to expose stereotypic body postures that can be related to two different…

Nonlinear amplitude dynamics in flagellar beating
TLDR
This work reveals a novel mechanism for the saturation of unstable modes in axonemal beating via the coupling of dynein kinetics and flagellum shape without the need of invoking a nonlinear ax onemal response.
Flagellar kinematics reveals the role of environment in shaping sperm motility
TLDR
The phylokinematic tree shows marked discordance from the phylogenetic tree, indicating that physical properties of the fluid environment, more than genetic relatedness, act as an important selective pressure in shaping the evolution of sperm motility.
Bimodal rheotactic behavior reflects flagellar beat asymmetry in human sperm cells
TLDR
The analysis reveals that the swimming strokes of human sperm are considerably more complex than previously thought, and that sperm may use their heads as rudders to turn right or left, and uncovers ambidextrous flagellar waveforms and shows that the cell’s turning direction is not defined by the rolling direction.
Flagellar energetics from high-resolution imaging of beating patterns in tethered mouse sperm
TLDR
Measurements of flagellar energetics indicate that the ion-channel regulating cysteine-rich secretory proteins (CRISPs) may also be involved in regulating mammalian sperm motility.
Hydrodynamics of flagellar swimming and synchronization
TLDR
It is proposed that direct elastic coupling between the two flagella of Chlamydomonas, as suggested by recent experiments, in combination with waveform compliance is crucial to facilitate in-phase synchronization of the twoFlagellar synchronized cells.
Nonlinear dynamics and fluctuations in biological systems (Habilitation thesis)
TLDR
This habilitation thesis addresses two central dynamical processes in cells and organisms: active motility and motility control and self-organized pattern formation and argues that measured non-equilibrium fluctuations of the flagellar beat result from stochastic motor dynamics at the molecular scale.
Synchronization in cilia carpets and the Kuramoto model with local coupling: Breakup of global synchronization in the presence of noise.
Carpets of beating cilia represent a paradigmatic example of self-organized synchronization of noisy biological oscillators, characterized by traveling waves of cilia phase. We present a multi-scale
Nonlinear dynamics and fluctuations in biological systems
Inspired by the coordinated beating of the flagellar pair of the green algae Chlamydomonas, we study theoretically a simple, mirror-symmetric swimmer, which propels itself at low Reynolds number by a
Long-term segmentation-free assessment of head–flagellum movement and intracellular calcium in swimming human sperm
TLDR
A novel methodology based on local orientation and isotropy of bio-images to obtain long-term kinematic and physiological parameters of individual free-swimming spermatozoa without requiring image segmentation (thresholding) is presented.
Gap Junctional Blockade Stochastically Induces Different Species-Specific Head Anatomies in Genetically Wild-Type Girardia dorotocephala Flatworms
TLDR
It is shown that after decapitation in G. dorotocephala, a transient perturbation of physiological connectivity among cells (using the gap junction blocker octanol) can result in regenerated heads with quite different shapes, stochastically matching other known species of planaria.

From Modes to Movement in the Behavior of Caenorhabditis elegans
TLDR
A map is constructed from the dynamics in this shape space to the trajectory of the worm along the agar to illustrate that changes in the continuous dynamics reveal subtle differences in movement strategy that occur among mutants defective in two classes of dopamine receptors.
Local and global measures of shape dynamics
TLDR
A simple, yet versatile, framework that provides multiple metrics of cell shape and cell shape dynamics is presented that finds that protrusions zigzag, while retractions remain roughly stationary along the boundary.
Active phase and amplitude fluctuations of flagellar beating.
TLDR
The analysis shows that flagellar fluctuations are dominantly of active origin, and it is demonstrated how the stochastic dynamics of individual motors can give rise to active small-number fluctuations in motor-cytoskeleton systems.
How molecular motors shape the flagellar beat
TLDR
The flagellar beat patterns are determined by an interplay of the basal properties of the axoneme and the mechanical feedback of dynein motors, which suggests a novel mechanism by which changes in basal compliance could reverse the direction of beat propagation.
Cell-body rocking is a dominant mechanism for flagellar synchronization in a swimming alga
TLDR
Realistic hydrodynamic computations and high-speed tracking experiments of swimming cells are presented that show how a perturbation from the synchronized state causes rotational motion of the cell body, which feeds back on the flagellar dynamics via hydrod dynamic friction forces and rapidly restores the synchronization state in the theory.

THE PROPULSION OF SEA-URCHIN SPERMATOZOA
TLDR
The object of this paper is to relate the propulsive speed of the whole spermatozoon to the form and speed of propagation of the bending waves generated by the tail and to consider the forces exerted on the tail as it moves relative to the surrounding medium.
Calcium-induced asymmetrical beating of triton-demembranated sea urchin sperm flagella

TLDR
Moving-film flash photography shows that asymmetrical flagellar bending waves are associated with premature termination of the growth of the bends while the bends in the opposite direction grow for one full beat cycle, and with unequal rates of growth of principal and reverse bends.
