Medical school in Southern India exposed me to the universally human nature of our profession, and also the wide spectrum of interests afforded to the life of a physician. Intrigued by the complexity of even the simplest physiological processes, I pursued higher mathematical training at Oxford University in England after graduating from medical school, completing a research doctorate in mathematical biology. I subsequently returned to clinical training, qualifying in internal medicine, neurology and epileptology. Since then, my career has been devoted to the care of patients with epilepsy, and the pursuit of research questions inspired by the phenomenology of everyday practice.

Clinical Interests

Adult epilepsy, with a focus on syndrome identification, management of refractory epilepsy, epilepsy surgery and clinical neurophysiology. I maintain an interest in general neurology and the internal medicine/neurology overlap. I am also interested in models of delivery of neurological and epilepsy care in resource-poor situations.

Research Interests

I follow several different themes with some mutual overlap. (i) Electrophysiology of cortical dynamics of the transition to epilepsy, and its reference to intrinsic brain state changes, e.g. the sleep-wake cycle, using a combination of signal processing and mathematical methods, (ii) MR imaging of epilepsy, attempting to design novel sequences and methods for focal epilepsy nonlesional by conventional methods, (iii) The cognition-epilepsy intersection in a variety of contexts, using electrophysiological and imaging methods, and (iv) Refining the diagnostic process in epilepsy and neurology by describing novel correlations or clinical phenomena, developing newer methods for analysis of diagnostic data, and investigating the cognitive process of decision making.

Teaching Interests

Academic medicine and teaching are inextricably linked. I have delivered lecture style classes to medical students, residents and fellows, in addition to regular clinic and hospital rounds-based teaching to rotating students and junior doctors. At the institutional level, I have delivered multiple grand-rounds presentations to interested departments (internal medicine, neurosurgery, etc.). I participate in city-wide, state-wide, and national workshops on epilepsy-related topics.
