Welcome from Dr. Mark Anderson

Dr. Mark Anderson

The Department of Medicine at the Johns Hopkins University School of Medicine is committed to the progress of biomedical discovery, teaching the next generation of doctors and scientists and the improvement of health in our neighborhood and around the globe.

This is a complicated and challenging time for Baltimore and the world. From the killings of Black Americans such as Freddie Gray and George Floyd to the ensuing riots, the indictment of police and the enduring uncertainty about how the core issues that resulted in these circumstances can be resolved provide a heavy backdrop for the work we must do to move forward. These issues have been brought to light again by the global COVID-19 pandemic that has disproportionally affected minority populations and brought social and racial injustice and inequity to the forefront of public health. I believe there are many potential ways we, Department of Medicine faculty and staff, can make a difference to our community, our patients and to one another.

We are people serving people, to promote health and alleviate suffering locally and globally. This is our mission statement, born out of discussions that followed the death of Freddie Gray that explored how the issues of race and background inform our worldview, relationship to our colleagues, daily lives and experience at work. We aim to improve our environment, build a stronger culture of respect and help us to become better change agents to improve our surrounding community. We do this through our Department of Medicine Diversity Council, the Task Force on Women's Academic Careers in Medicine and initiatives like Medicine for the Greater Good, which trains healthcare professionals how to mitigate health-related inequities through community engagement. We became leaders in the fight against COVID-19, improving outcomes for patients with scientific innovations, educational resources and world-class clinical care.

Our department is made up of an amazing group of people who together provide cutting-edge patient care, maintain some the country’s top internal medicine training programs and conduct more externally funded research than almost anywhere else. It is difficult to summarize all the important work of the department, but to start, the Department of Medicine:

  • Has more than 650 full-time faculty members across 18 academic divisions
  • Employs nearly 3,000 staff members
  • Provided care for over 300,000 clinic visits last year
  • Discharged more than 25,000 patients from The Johns Hopkins Hospital and Johns Hopkins Bayview Medical Center last year
  • Is primarily based at our two campuses in Baltimore
  • Has outlying clinical locations across the Baltimore-Washington metro area
  • Maintains an annual research portfolio of more than $175 million
  • Partners with the Johns Hopkins University School of Medicine, currently ranked No. 2 in internal medicine by U.S. News & World Report
  • Home to two outstanding residencies with distinct identities and hospital homes
  • Home to the Osler Medical Residency, consistently ranked the top internal medicine residency program by program directors

I am honored to serve as the director of this outstanding department. If you have questions or comments, please don’t hesitate to contact us.

Our department was founded on excellence, and we will never stop striving for greatness. We promote personal and professional development to help the talented individuals that make up our department shine in order to benefit Hopkins, Baltimore and the world.
