I am a Professor of Pediatrics and Medicine at Duke University School of Medicine, a Medical Ethicist and Pediatric Oncologist. I have been photographing for a number of years but have only recently (in the last 2 years or so) really started devoted more time and energy to it. I use both a Leica M240 and a Canon 5D Mark III system. I enjoy nature and landscape photography when traveling to open spaces, but street and architectural photography most other times.
