Dr Sandeep Jauhar is a US cardiologist and writer for The New York Times. He has written three books. His most recent, Heart: A History, is beautifully written and tells the colourful history of the doctors who risked their careers and the patients who risked their lives for us to learn what cardiologists today know about the heart. As well as The New York Times, Dr Jauhar’s opinions have appeared on NPR, CNN and MSNBC, and his essays have been published in Time Magazine, The Wall Street Journal and Slate.
