Experiments concerning the mechanism of cytokinesis in Caenorhabditis elegans embryos
… of different spindle parts – microtubule asters and the midzone - to cytokinesis furrow positioning. I developed a UV laser-based severing assay that allows the spatial separation of the region midway between the asters and the spindle midzone. The spindle is severed asymmetrically between …

Molecular organization of the actin cortex in apical constriction and epithelial folding
… uniformly distributed myosin to contract into asters drives nonmuscle contractility. Here, I provide insight into the mechanism of nonmuscle contraction by demonstrating that the apical actin cortex and associated proteins are spatially organized in epithelia. In addition, I demonstrate that …

Modeling Pattern Formation in Biopolymer Systems induced by Reaction Kinetics and Molecular Motors
… bundle-like structures and regular lattices of asters respectively. In the oscillatory case, there is competition between traveling and standing waves in one dimension and between traveling and alternating waves in two dimensions, the latter being a four mode solution built from two standing …

Self-organization of Microtubule and Associated Protein Map65
<p>One of the most fascinating micron-scale structures in the biological world is the cell cytoskele- ton, with numerous components of different sizes, shapes, and geometries working together. How the local interactions of these macromolecules and polymers in nano-scale help self- organize into …
