Role of Delta-Notch signalling molecules on cell-cell adhesion in determining heterogeneous chemical and cell morphological patterning

This study extends a vertex model of epithelial tissues to include contact-dependent signaling and mechanochemical coupling, showing that two-way interactions between cell mechanics and signaling can produce diverse patterns in cell size and shape.

Effective elasticity and persistence of strain in active filament-motor assemblies

This study investigates the persistence length of strain in active filament-motor assemblies, finding it depends on passive elasticity and motor kinetics under different deformation conditions.

Synchronized oscillations, metachronal waves, and jammed clusters in sterically interacting active filament arrays

This study uses simulations to show that steric interactions and surface roughness in active filament arrays can generate synchronized oscillations, metachronal waves, and jammed clusters.

Role of cell polarity dynamics and motility in pattern formation due to contact dependent signalling

This study investigates how cell polarity dynamics and motility influence spatiotemporal patterning of signalling molecules through contact-dependent interactions.

Instabilities and Spatiotemporal Dynamics of Active Elastic Filaments

This study investigates the dynamic buckling instabilities of elastic filaments driven by tangential forces in the presence of obstacles or cargo, identifying two distinct instability states and their dynamics.

Filament extensibility and shear stiffening control persistence of strain and loss of coherence in cross-linked motor-filament assemblies

The paper investigates how filament extensibility and shear stiffening affect strain persistence and coherence loss in cross-linked motor-filament assemblies using theoretical and simulation approaches.
