Biography

Jesse has Bachelor of Engineering, Master of Engineering, and Doctor of Philosophy (to be conferred) degrees in Bioengineering from the University of Auckland. His research to date has focused on nervous system control of heart rhythm and the mechanisms that contribute to development of cardiac arrhythmias. His particular strengths are in electrophysiological measurement, imaging and microscopy, data analysis, image processing, software development and computational modelling. The overall goal of his research is to develop new technologies to aid in the diagnosis and treatment of neurogenic cardiac arrhythmias.

Research | Current

Jesse's current postdoctoral research with A/Prof. Montgomery is focussed on determining how changes in the communication within the network of neurons that innervate the heart can contribute to triggering episodes of atrial fibrillation in the context of hypertension and heart failure.  Mechanisms that alter neuronal function and neurotransmission in heart failure have been identified but little is known about the properties of the connections – termed ‘synapses’ – formed by intracardiac neurons.  Our novel hypothesis is that changes in the structure and function at these synapses alter autonomic tone to the heart and enhance the likelihood of atrial arrhythmia.
