Where am I now?
I have been awarded a Sir Henry Dale Fellowship, by the Royal Society and the Wellcome Trust, which will start in October 2021. This 5 year fellowship will support the further development of my research group in the Division of Cardiovascular Medicine at the University of Oxford.

Research project title: Defining Key Mechanisms of HCM and DCM Variant Pathogenicity in a Human Cellular Model of Disease
Research summary:
We investigate the role of mutations in key contractile proteins in hypertrophic cardiomyopathy (HCM). The laboratory focuses on CRISPR/Cas-9 engineering of human induced pluripotent stem cells. These cells can be differentiated into cardiomyocytes, which are used to model human heart disease in a dish.

Biography:
I have always been fascinated about the way the heart functions, and the processes that govern how the muscle of the heart is able to efficiently pump blood around the body. I spent my doctoral years dissecting key mechanisms of heart muscle regulation. I then moved to Boston to study how these mechanisms can go wrong in disease. I have since returned to Oxford to begin my own research group to identify these key mechanisms of disease and understand how we can design novel therapies for patients with these cardiac conditions.
