Turbulent coherent structures and early life below the Kolmogorov scale
Madison S. Krieger, Sam Sinai, Martin A. Nowak
A great number of biological organisms live in aqueous environments. Major evolutionary transitions, including the emergence of life itself, likely occurred in such environments. W…
Tunable wrinkling of thin nematic liquid crystal elastomer sheets
Madison S. Krieger, Marcelo A. Dias
Instabilities in thin elastic sheets, such as wrinkles, are of broad interest both from a fundamental viewpoint and also because of their potential for engineering applications. Ne…
Effects of motion in structured populations
Madison S. Krieger, Alex McAvoy, Martin A. Nowak
In evolutionary processes, population structure has a substantial effect on natural selection. Here, we analyze how motion of individuals affects constant selection in structured p…
Microorganism billiards in closed plane curves
Madison S. Krieger
Recent experiments have shown that many species of microorganisms leave a solid surface at a fixed angle determined by steric interactions and near-field hydrodynamics. This angle…
Interfacial fluid instabilities and Kapitsa pendula
Madison Ski Krieger
The onset and development of instabilities is one of the central problems in fluid mechanics. Here we develop a connection between instabilities of free fluid interfaces and invert…
Microscale locomotion in a nematic liquid crystal
Madison S. Krieger, Saverio E. Spagnolie, Thomas R. Powers
Microorganisms often encounter anisotropy, for example in mucus and biofilms. We study how anisotropy and elasticity of the ambient fluid affects the speed of a swimming microorgan…
Minimal model for transient swimming in a liquid crystal
Madison S. Krieger, Marcelo A. Dias, Thomas R. Powers
When a microorganism begins swimming from rest in a Newtonian fluid such as water, it rapidly attains its steady-state swimming speed since changes in the velocity field spread qui…
Locomotion and transport in a hexatic liquid crystal
Madison S. Krieger, Saverio E. Spagnolie, Thomas R. Powers
The swimming behavior of bacteria and other microorganisms is sensitive to the physical properties of the fluid in which they swim. Mucus, biofilms, and artificial liquid-crystalli…
