Research/Teaching Interest:

  1. Neuroscience
  2. Neurocardiology

My expertise in integrative neuroscience aimed at finding treatments and cures for neurological disorders. My work has focused on long term neuronal plasticity, specifically in the context of pathological injury within the central nervous system. My recent work has focused on neuronal interactions that occur among the central and peripheral neural networks playing a major role in controlling cardiac functions. Imbalances within this control system are associated with heart disease and have deleterious consequences, including the progression into heart failure. Neuromodulation therapy has emerged as a novel approach to treat such disease processes at their root cause, namely restoring neuronal balance within the nervous system and thereby restoring cardiac function.

Title: Sensory consequences of autonomic regulation therapy in the treatment of heart disease.
Objective: To determine the effect of heart disease (c.f. pressure overload) on neuronal function/plasticity at the level of the nucleus of the solitary tract. Next, to determine the efficacy of VNS to mitigate these neuronal changes, preserving cardiac pumping function.

Title:
Evaluation of vagal nerve stimulation (VNS) for treatment of heart failure in dogs.
Objective: To determine the effect of chronic VNS on heart disease models, particularly in integrated cardiac function and its impact on the progression of diastolic heart failure using a renal wrap dog model.
