Center for Molecular Medicine

Dedicated to understanding the intricacies of cellular signaling, the Center for Molecular Medicine was built on Caltech's successes at the interface of chemistry and biology. It is focused on determining how complex systems of molecules interact to create the pathways that regulate the lives of cells and allow them to respond to their environments. Rather than just studying a complex biomolecule in isolation, an understanding of how it is part of a larger path of molecules is the purpose of its establishment. The Center was made possible by a generous grant from the Gordon and Betty Moore Foundation.

If use of the Center instrumentation has contributed significantly to your research, we request that you cite the Center in the acknowledgments section of your publication. For example: "This work was supported by…, and by the Center for Molecular Medicine at California Institute of Technology."
