Research Opportunities and Announcements

Duke Center for Geriatric Surgery Research Scholars Program

The DCGS Scholars Program provides funding of up to $20,000 per project for 12 months to catalyze investigations of key questions in geriatric surgical outcomes research. The goals of this program are to foster new collaborations among Duke researchers, support research teams in obtaining preliminary data that will be used to apply for larger awards, and provide opportunities for mentoring and training for junior faculty, residents and medical students.

Key Dates:

  • 2022 RFA coming soon

Funding Opportunities

  • Testing Interventions for Health-Enhancing Physical Activity (R01 - Clinical Trial Optional) - PAR-18-324 

  • Developing Interventions for Health-Enhancing Physical Activity (R21/R33 - Clinical Trial Optional) - PAR-18-307

  • Improving Patient Adherence to Treatment and Prevention Regimens to Promote Health (R01 Clinical Trial Optional) - PA-18-722
