In this episode, Itai and Martin talk with Arjun Raj, Professor of Genetics at the University of Pennsylvania. Arjun understands the functioning of biological cells using a bag of tricks that he carries from problem to problem; the art of science, he posits, lies in figuring out what tricks will tell you what answers to what problems. Arjun thinks that we are all born night scientists, and that it's day science that needs to be learned. The ultimate goal of life as a scientist, he believes, is not so much writing papers, but building people. Arjun has received many prizes, including the NIH Director's New Innovator Award. His lab pioneered tools for studying biological processes using state of the art imaging and sequencing technologies. For more information on Night Science, visit www.night-science.org .
