Cardiac and skeletal muscle regulation and inherited diseases. Molecular basis of striated muscle contraction.
My research goals are; (i) to understand how allosteric mechanisms in troponin modulate the muscle response to calcium-dependent activation; (ii) to develop new genetic and molecular strategies for the reversal of cardiomyopathies, (iii) to define the role of nuclear troponin in heart development and disease; and (iv) to understand how post-translational modifications fine-tune muscle contraction and their roles in cardiac disease.
