Research

Research in the Manning group follows two interconnected thrusts: Collective behavior in biological tissues and deformation in disordered solids. Click sub-topic headings below for additional detail.

Collective behavior in biological tissues
Groups of cells exhibit interesting collective behavior that emerges from simple interactions between individual cells. We search for universal features and rules that govern this far-from-equilibrium behavior.

Deformation in disordered solids
If you push a pile of sand very lightly, it will respond elastically, but if you push beyond an extremely low threshold, it will begin to flow. But the system that it flows into will be qualitatively similar to the state it was just in. We are studying that marginal transition in low dimensional systems (2D and 3D):
