Armstrong Institute Leadership

The leader of the Armstrong Institute serves two broad roles. As institute director, this individual oversees the scholarly work of our faculty and staff, who are world leaders in advancing the science of patient safety and quality improvement at Johns Hopkins, across the United States and internationally. In the second role, as Johns Hopkins Medicine senior vice president for patient safety and quality, this leader coordinates and supports efforts to improve care across our corporate health system. Combining these roles in one individual helps to infuse academic rigor in improvement efforts, while ensuring that research is grounded in operational realities.

There is currently a national search for a new director and executive vice president for patient safety and quality. During this period, we have two interim leaders – one for each role – who are working together to meet our institute’s and health system’s goals.

Interim Senior Vice President for Patient Safety and Quality, Johns Hopkins Medicine

As vice president for quality for the Johns Hopkins Hospital and Johns Hopkins Health System, Ms. Demski has been instrumental in developing a robust, disciplined process to improve results in quality and safety of care.
