The Chang Lab studies fundamental questions concerning spatial organization within a single cell: How do cells determine where they should divide, and where should they polarize? How does pattern formation occur in the single cell? How do cellular components determine cell shape and size? How might cells sense their own shape and size?
To address these questions, we primarily study a eukaryotic model organism, the fission yeast Schizosaccharomyces pombe.
These are simple rod-shaped cells that display a highly uniform size and rod-shape morphology. We seek to elucidate quantitative molecular and biomechanical mechanisms underlying the dynamic cellular processes responsible for morphogenesis of the cell. In our work, we use interdisciplinary approaches, combining the expertise and perspectives of cell biologists, geneticists, physicists, and engineers. We seek to develop new approaches to manipulate and assay processes in living cells, using microscopy, genetics, and micro-fabricated devices.
Current projects include: regulation of cytokinesis, placement of the cell division plane, cell polarity, dynamics of microtubules and actin, biomechanics of cell morphogenesis and sensing of cell shape and size.
