Our nervous system is a highly parallel high-performance computing network with trillions of connections called synapses and billions of processing elements called neurons supported by trillions of glial cells. My research focuses on developing theories of workings of this complex system in health and disease by examining the structure, function and molecular basis. We use interdisciplinary approaches including electrophysiology, mathematical modeling and simulations, bio-hybrid systems and also collaborate with molecular biologists and clinical scientists. We are currently focusing on developing mechanistic understanding of disease dynamics in progressive neurodegenerative motor neuron disease, Amyotrophic Lateral Sclerosis (or ALS). Our results have begun to shed light on how the disease alters motor neuron physiology at pre-symptomatic stages and may lead to the development of muscle dysfunction. We are now seeking to develop a dynamic longitudinal map of electrophysiological and molecular changes in vulnerable brainstem sensorimotor circuits to help identify early biomarkers and therapeutic targets. Along the way, we wish to make significant discoveries answering intriguing questions on selectivity and vulnerability in disease with broader implications to suggest strategies for disease management.
