Cell walls are found throughout the tree of life (even in some animals!) and in most cases they serve similar functions of strengthening and protecting cells.  Dr. Braybrook’s research focuses on cell walls found in multicellular organisms such as plants and brown algae. In her first talk, Braybrook explains that cell walls are made of cellulose which forms long strong fibers, a gel matrix such as pectin or alginate in which the cellulose is embedded, and cross-links such as hemicellulose or lignin that provide strength and hold the wall together. By improving our understanding of cell wall structure and biology, Braybrook’s research may help facilitate our use of plants and seaweed for biofuels and other products.
