Evaporation-Induced Pattern Formation and Wetting in Active Microtubule-Kinesin Droplets
Vahid Nasirimarekani, Mehrana R. Nejad, Olinka RamÃrez-Soto +4
Active networks composed of biopolymers and motor proteins provide versatile biomimetic systems that have advanced active matter physics and deepened our understanding of cytoskele…
Collective synchrony in confluent, pulsatile epithelia
Wenhui Tang, Mehrana R. Nejad, Adrian F. Pegoraro +2
Collective cell migration lies at the intersection of developmental biology and non-equilibrium physics, where active processes give rise to emergent patterns that are biologically…
Thin active nematohydrodynamic layers: asymptotic theories and instabilities
Mehrana R. Nejad, L. Mahadevan
Starting from a three-dimensional description of an active nematic layer, we employ an asymptotic theory to derive a series of low-dimensional continuum models that capture the cou…
Coarse-graining dense, deformable active particles
Mehrana R. Nejad, Julia M Yeomans
We coarse-grain a model of closely-packed ellipses that can vary their aspect ratio to derive continuum equations for materials comprising confluent deformable particles such as ep…
Cellular dynamics emerging from turbulent flows steered by active filaments
Mehrana R. Nejad, Julia M. Yeomans, Sumesh P Thampi
We develop a continuum theory to describe the collective dynamics of deformable epithelial cells, using two tensor order parameters to distinguish the force-generating active filam…
