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…
