About

Our lab seeks to understand how the protein kinase family organises complex intracellular communication networks. We are particularly interested in acquiring a deep understanding at the molecular level of the catalysis-independent signalling functions of kinase/pseudokinase scaffold.

We employ a multidisciplinary approach including kinase biochemistry and biology, structural biology (X-ray crystallography and cryo-electron microscopy), assay development, high-throughput screening, proteomics, imaging and chemical biology to gain high-resolution insights into kinase/pseudokinase signaling proteins.
