Rebecca Page joined the Cell Biology Department in December 2020, as a full professor. Her research concerns how we sense and react to our environment which is communicated in the cell by vast networks of highly dynamic, interacting proteins. These interactions are regulated in both space and time, and it is this tight regulation that allows signals from outside of the cell to be rapidly and precisely transmitted to the nucleus leading to the appropriate, and healthy, cellular response. We integrate structural biology, cell biology, genetics and biochemistry in order to understand how these signals in both prokaryotes and eukaryotes are communicated in the cell at atomic resolution.
