My lab investigates how metabolic and genetic diseases damage the heart and kidneys, using human stem cell-derived models to understand disease mechanisms and identify better treatments.

We work across two major programs. In cardiometabolic disease, we model how metabolic stress drives dysfunction in the heart and kidneys, with a focus on diabetes and cardiorenal syndrome. We have developed human cardiac microtissue and cardiorenal co-culture platforms that enable real-time functional assessment of both organs under disease conditions. In Friedreich ataxia, a rare genetic condition and the most common inherited ataxia, cardiac disease is the leading cause of death and no treatment currently exists. We use patient-derived cardiac models and mouse models to investigate disease mechanisms and test lipid and mRNA-based therapeutic strategies.

I hold a National Heart Foundation Future Leader Fellowship and lead an externally funded program with national and international collaborators spanning lipidomics, nephrology, bioengineering, and clinical cardiology.
