Research Program Overview

Lymphatic vessels are a crucial but often overlooked component of the cardiovascular system. These specialised vessels return fluid and proteins from our tissues to the bloodstream, absorb lipids from the digestive tract, and direct the trafficking of immune cells throughout our bodies, thereby controlling immunity. Abnormalities in the development or function of lymphatic vessels are associated with human disorders including vascular malformations, lymphoedema, inflammatory diseases, neurological disorders and cancer. Despite the integral role played by lymphatic vessels in health and disease, little is known about the genes and signals that direct their construction.

Our research seeks to understand how the lymphatic vessels are built during development and how this process goes wrong in human disease states. We investigate mouse and human genetics in addition to cell, molecular and developmental biology, in order to define the genes and signalling pathways that underpin lymphatic development and function in health and disease. We are particularly interested in understanding the genetic and developmental basis of human lymphatic diseases, defining how the identity of cells in the lymphatic system is programmed during development and investigating the process by which lymphatic vessel valves are built. Our ultimate aim is that by understanding these processes, we will be able to develop more effective treatments for patients affected by lymphatic vascular disease.

Current Research Projects

  • Defining the genetic and developmental basis of human lymphatic vascular disorders including lymphatic vascular malformations and lymphoedema.
  • Understanding how lymphatic vessel identity is programmed by transcription factors.
  • Characterising the function of novel genes in lymphatic vessel growth and development.
  • Defining the genes and signalling pathways important for lymphatic vessel valve development.
  • High resolution imaging of lymphatic vessel growth and development.
