Proteins are the 'molecular machines' of the cell, and perform many of the essential functions in biological systems. In many cases, however, proteins do not act alone but rather physically interact with other proteins and other types of biomolecules to carry out their functions. These sets of interacting proteins, termed 'protein complexes' are themselves organized into larger networks of proteins that function in a coordinated manner. Understanding which proteins interact with which, and where and when these interactions occur, is therefore essential to understanding protein function. The broad goal of our research is to understand these protein interaction networks, ultimately defining a 'systems-wide' protein interaction map that will both provide insights into the function of individual proteins as well as the organization of proteins within the cell.

Biological Questions

Our work focuses on understanding protein interactions in the context of human disease and development. Specifically, we are interested in protein interaction networks in cancer cells, and understanding how somatic mutations in important oncoproteins perturb protein interactions networks to promote tumourigenesis. Most recently we have focused on uncovering the network of protein-protein interactions that underlie Wnt signalling, a critically important signal transduction pathway during embryogenesis, and in many human cancers. In addition, we have used proteomic and computational techniques to begin to understand how embryonic stem cells maintain pluripotency, the capability to differentiate into many different tissues of the body.


We are very much technology-focused, using and seeking to improve techniques for defining protein interaction networks. We use proteomic techniques (proteomics allows us to identify and quantify thousands of proteins at once) and also develop computational and statistical techniques for analysing the large amounts of data that proteomics experiments generate, and to organize those data into biological networks.
