Jamie Vandenberg is an international authority on cardiac ion channels and has made breakthrough discoveries in understanding how these channels work and how drugs interact with these channels; contributing significantly to our understanding of the molecular basis of cardiac arrhythmias. In recognition of his expertise in this area he has been invited to sit on an international panel advising the Food and Drug Administration (USA) on how to best tackle the problem of drug-induced cardiac arrhythmias, which has been the commonest cause for drugs to be withdrawn from the market after regulatory approval.
