Dr. Ulatowski is one of the world’s leading investigators into the regulatory mechanisms of cerebral blood flow and oxygen delivery to the brain. His research included the development and application of invasive and noninvasive techniques for monitoring brain function, fluid management, and sedation in patients with brain injury, use of novel oxygen carriers in blood, and new techniques and therapies for stroke.

A new area of exploration for Dr. Ulatowski is that of health service research toward the design of safer systems surrounding the care of perioperative/periprocedural patients. Anesthesiologists, intensive care physicians, and pain physicians have led the way in creating safe environments in individual ORs, ICU rooms, and interventional pain procedure rooms. The next generation of perioperative physicians will create even safer environments around OR suites, ICUs, and pain clinics to ensure better preparation, safe passage of patients, to prevent even the occasional mistake made by well-meaning practitioners. They will use information technologies and analytical business tools to improve outcomes (medical, financial, human resource, and patient satisfaction). Dr. Ulatowski is helping to develop a new generation of perioperative safety experts and disseminate this knowledge around the world.
