In the pediatric intensive care unit at Johns Hopkins Hospital in Baltimore, Elizabeth "Betsy" Hunt, PhD, regularly uses simulations to prepare medical students and staff for emergencies, such as cardiac arrests. For Hunt, simulation is all about improving teamwork, communication, and multitasking skills. Her research on resuscitation and critical care medicine led to her appointment as the first director of the hospital's Simulation Center in 2004, when she worked with engineers and architects to design and build the $5 million facility that opened its doors this year.
