Research and discoveries

Using molecular and cell biology techniques and innovative mouse models, our current research focuses on developing new treatments for Duchenne muscular dystrophy and cancer cachexia.

Research themes

Cancer cachexia and muscle wasting

How does cancer disrupt tissue health and regeneration?

Chronic diseases fundamentally alter the biological systems responsible for tissue maintenance and repair. We investigate how inflammation, cancer and systemic stress influence stem cell behaviour, regenerative capacity and tissue health. We combine stem cell biology, genomics and disease models to uncover how cancer reshapes regenerative tissues and drives muscle wasting.

Stem cells and regenerative medicine

How do tissues maintain and repair themselves?

Muscle stem cells spend most of their lives in quiescence, ready to self-renew and repair muscle after injury. We study the transcriptional programs that keep these cells in reserve and the signals that call them into action, and how those programs change during regeneration, aging and disease.

  • quiescence
  • self-renewal
  • repair
  • single-cell genomics
  • cellular heterogeneity
  • tissue microenvironments

Gene regulation and cell fate

How are cellular decisions controlled?

Our work explores the gene regulatory networks that control cellular identity, differentiation and adaptation in health and disease.

Single-cell and systems biology

How do complex cellular ecosystems respond to change?

Advances in single-cell and multi-omic technologies allow us to examine tissues as dynamic cellular ecosystems. We seek to identify the cellular states, interactions and adaptive pathways that emerge during regeneration, aging and disease.

  • cellular heterogeneity
  • tissue microenvironments
