Jacques Dumais
Plant morphogenesis and mechanics

Mechanics of cell wall expansion and how it controls morphogenesis at the cellular and multicellular levels. Current projects include an experimental and theoretical analyses of tip growth morphogenesis, cell division, meristem growth, and phyllotaxis. Mechanics of fast movements in plants and fungi such as the closure of the Venus flytrap, spore ejection in fungi and ferns, and pollinarium ejection in orchids.
