Chris Toepfer

Background and research interests

Chris completed his PhD at Imperial College London under the supervision of Professor Michael Ferenczi and Dr James Sellers (National Heart Lung and Blood Institute, National Institutes of Health, USA), studying how heart muscle function is adapted in human health and disease.  He subsequently began his postdoctoral work with the support of a Sir Henry Wellcome Postdoctoral Fellowship with Professors Christine and Jonathan Seidman at Harvard Medical School and Professor Hugh Watkins at the Radcliffe Department of Medicine, Oxford.  In this work he established key mechanisms of inherited heart muscle disease in two of the most common forms of hypertrophic cardiomyopathy (HCM).

Chris has subsequently established the laboratory of 'Cardiac Physiology and Disease Modelling' at the University of Oxford, supported by a Sir Henry Dale Fellowship from Wellcome and additional funding from the British Heart Foundation (BHF).  The research group is investigating the mechanisms that drive inheried cardiomyopathies, including both HCM and dilated cardiomyopathies (DCM).  His team do this by using human induced pluripotent stem cells (hiPSCs) to produce human heart cells in the dish (hiPSC-CMs).  Using genetic engineering (CRISPR/Cas-9) the team introduce patient specific mutations into human heart cells to study disease mechanisms, with the aim of developing new genetic cures for inherited heart muscle diseases.
