Greenwall Fellowship in Bioethics

The next call for nominations will open in March 2025.

The overall purpose of the Greenwall Fellowship in Bioethics is to provide talented, early-career bioethics scholars with the opportunity to experience and participate in evidence-based healthcare or public health studies and policy-making process that improve the care and access to care of patients in domestic and global health care systems. The Greenwall Fellowship in Bioethics enables young investigators to participate actively in the work of the National Academies of Sciences, Engineering, and Medicine (the National Academies) and to further their careers as future leaders addressing bioethics issues in clinical care, biomedical research, and public policy. Supported through an endowment from the Greenwall Foundation, the program especially welcomes nominations of historically underrepresented candidates.

The Greenwall Fellowship is part of the NAM Fellowships for Health Science Scholars program. See all opportunities >>

Fellowship Description

The Greenwall Fellowship in Bioethics is awarded for a two-year period. During this time, the fellow is expected to continue to work at their main academic post, while being assigned to a health- and medicine-related board of the National Academies. The boards are:

  • Children, Youth, and Families,
  • Food and Nutrition,
  • Global Health,
  • Health Care Services,
  • Health Sciences Policy, and
  • Population Health and Public Health Practice.

The fellowship requires a 10- to 20-percent commitment of time for two years, and includes attendance at a one-week orientation to health policy, the NAM Annual Meeting in October and the meetings of the assigned board. Domestic travel expenses are covered for participation in approved fellowship activities. Additionally, the fellow will participate actively in the work of an appropriate study committee or roundtable, including contributing to its reports or other products. Studies that would enable the potential for the fellow to contribute to the value of integrating medicine and public health will be identified.

This experience will introduce the Greenwall Fellow to a variety of experts and perspectives, including legislators, government officials, industry leaders, executives of voluntary health organizations, scientists, and other health professionals. In addition, each fellow will be assigned to an NAM member who will serve as a senior mentor during the two years of the fellowship.

A flexible research grant of $25,000 is awarded to each Greenwall Fellow, which will be administered through the appropriate department in the fellow’s home institution to advance the fellow’s professional and academic career. This grant is not intended for use as a salary offset for the fellow, and no indirect costs are allowed.
