Neurosurgeon Benjamin Carson, director of pediatric neurosurgery at Johns Hopkins University, discusses the decision-making process inside and outside the operating room. He is best known for operating on conjoined twins, most recently the Bijani sisters from Iran. This is the first of a three-part series on how top decision makers do their jobs.
Correction April 15, 2005
We incorrectly reported that Dr. Benjamin Carson was the first to successfully separate twins connected at the head; there were other doctors before him.
