Nirav Patel, M.D.
Nirav moved to the United States in 2001 following medical training and the most part of medical residency in London, England. He joined Penn in 2004 having completed residency in Internal Medicine. After completing fellowships in pulmonary and critical care medicine, Nirav commenced a fellowship in sleep medicine. He is currently a post-doctoral fellow in the Center for Sleep and Respiratory Neurobiology and a clinical fellow in the Division of Sleep Medicine. Nirav’s concomitant exposure to the domains of sleep and public health has led him to an interest in the public health aspects of ‘sleep practice’.
Nirav’s research focus is in the sociology of sleep. Sleep is a ubiquitous activity that occupies one-third of our lives. The fact that millions worldwide do not sleep ‘well’ for one reason or other, translates to enormous direct and indirect costs by way of lost productivity, sick days, road traffic accidents, medical illness, and early mortality. In spite of this, the priority and interest in the subject of societal sleep practice is limited. His work aims to uncover differences in ‘sleep practice’, ‘sleep priority’, and sleep quality among social and neighborhood strata. Hypothesized differences, he believes, may also explain part of the well-known social-health gradient of society. Intervention on a grass-roots level would be required to positively affect sleep practice.
