James Scheulen is the chief administrative officer for emergency medicine and capacity management for Johns Hopkins Medicine and president of Johns Hopkins Emergency Medical Services. He is responsible for the operations of five Johns Hopkins Health System emergency departments, which together manage nearly 300,000 patient visits each year. Scheulen is considered an expert in hospital and emergency department operations, and is a leader in applying system engineering concepts to health care management.

Scheulen is the founder and director of the Hopkins Access Line and Johns Hopkins Lifeline critical care transportation service. As chief administrative officer, he leads efforts to manage hospital capacity for Johns Hopkins Medicine, guiding institutional efforts at process improvement and operationalizing a one-of-a-kind command center for hospital capacity optimization.

Scheulen is active in the leadership of pre-hospital emergency medical services (EMS) and emergency preparedness for Johns Hopkins and the state of Maryland, and was appointed by the governor of Maryland to the EMS board, which oversees the operation of all EMS activity in the state. With the director of the Department of Emergency Medicine, Scheulen is responsible for the creation and ongoing operations of the Johns Hopkins Office of Critical Event Preparedness and Response (CEPAR), designed to ensure a coordinated response to critical events across the Johns Hopkins enterprise.
