Research focus:

Our group investigates the importance of redox signalling and mitochondrial dysfunction in vivo in the regulation of metabolic health and ageing. We exploit the advantages of Drosophila as a powerful pre-clinical model for accelerated discovery, complemented by translational studies in the context of human disease.

About me:

I was attracted to the LMS by its exciting multi-disciplinary research environment. These synergistic interactions allow us to explore, validate and translate our findings across the model organism pipeline, through to collaborating with clinicians in the Faculty of Medicine at Imperial. Besides research, I’m involved in the institute’s Athena Swan initiative, which promotes gender balance in science, chairing the ‘Work-Life Balance’ working group and organising outreach events such as the ‘LMS Bring your Family to Work’ day.

My Research

Redox metabolism

Redox signalling is a critical process within the cell essential for key signalling pathways. We are working to better understand the molecular processes that guide its role in metabolism, disease, and ageing, and to uncover novel pathways and potential therapeutic targets.
