S. J. Singer

S. J. Singer, or Seymour J. Singer, was a prominent American cell biologist known for his research on how cells move and organize themselves. Along with colleagues like Garth L. Nicolson, he helped develop the fluid mosaic model of cell membranes, describing them as dynamic structures made of lipids and proteins. His work provided insight into cell motility, signaling, and the behavior of the cell's internal framework. Singer's contributions are fundamental to understanding cell function and have influenced many areas of biological and medical research.
