Join Dr. Jeff Jarvis as he interviews podcase friend and frequent contributor, now-Dr Tanner Smida for the first of a two-part interview where we discuss his defense of his PhD. Dr Smida discusses four papers that inform cardiac arrest resuscitation, as well as lessons he learned about conducting well-designed observational studies.

Although his dissertation was built around only 4 papers, here is Dr Smida’s entire bibliography:
