Certain cell signaling pathways are implemented by assembling their components on scaffolds and/or restricting their lateral mobility in a membrane. This makes it difficult to study the nodes where pathways interact using traditional biochemical techniques. Cells display dozens or even hundreds of molecules at their surface, that receive incoming signals and activate one or more intracellular signaling pathways. The challenge to cell biologists is to discover how the cells are sorting, editing, and refining this information at the next level. The aim of my group is to discover principles of how cells deal with such complexity.
