DOI: 10.1103/physreve.106.044706
Abstract: Topological defects are increasingly being identified in various biological systems, where their characteristic flow fields and stress patterns are associated with continuous active stress generation by biological entities. Here, using numerical simulations of continuum fluctuating… read more here.

DOI: 10.1126/sciadv.aar2847
Abstract: The interplay between network percolation and myosin-generated stress propagation leads to dynamically distinct steady states in cortices. Biological functions rely on ordered structures and intricately controlled collective dynamics. This order in living systems is typically… read more here.

DOI: 10.1371/journal.pone.0214510
Abstract: There is considerable debate regarding whether mandibular morphology in ungulates primarily reflects phylogenetic affinities or adaptation to specific diet. In an effort to help resolve this debate, we use three-dimensional finite element analysis (FEA) to… read more here.

DOI: 10.7554/elife.34460
Abstract: Mechanical forces have emerged as coordinating signals for most cell functions. Yet, because forces are invisible, mapping tensile stress patterns in tissues remains a major challenge in all kingdoms. Here we take advantage of the… read more here.
