Research Training

Summer Internship Program (SIP)

This program is available to:

An opportunity for students in college, graduate, and professional school to perform a summer research internship in the Intramural Research Program at the NIH.

About this program

This program is for college, graduate and professional students interested in exploring careers in research and healthcare. These are full-time research positions within one of the NIH Institutes and Centers (IC) in the NIH Intramural Research Program. Research groups are located on all NIH campuses, including the main campus in Bethesda, MD.

Summer interns work in a research groups directed by a Principal Investigator (PI). We offer research opportunities in the biomedical, behavioral, and social sciences with opportunities to explore basic, translational, and clinical research. Students interested in biology, engineering, epidemiology, psychology, mathematics, chemistry, pharmaceutical sciences, nursing, physics, computer science, bioinformatics, and other health-related fields are invited to apply. Summer interns may not work in administrative offices or outside of the NIH IRP.

In addition to an intensive research experience, our summer interns have access to:

We also sponsor a Graduate and Professional School Fair in July and Summer Poster Day in early August, where our interns share their research with the NIH community.

Diversity and inclusion

Diversity strengthens our community. We welcome applicants from diverse backgrounds and strongly encourage applications from individuals:

  • from racial and ethnic groups that have been underrepresented in biomedical research and healthcare fields
  • with disabilities
  • who are/were Pell Grant-eligible in college
  • who are/were enrolled in Tribal Colleges and Universities, community colleges, Hispanic-serving institutions, or Historically Black Colleges and Universities (HBCUs)
  • who identify as LGBTQ+
  • disadvantaged by life circumstances that have negatively impacted their educational opportunities.

SIP cohort programs

Our goal is to support diverse students to enter careers in research and healthcare. To help us achieve this, we sponsor summer cohort programs.

Summer interns in these programs  have access to all resources of the broader SIP program and also participate in orientation, leadership, professional development,  and well-being programs as part of a cohort or  learning community. The curriculum of each cohort program is tailored to the educational needs of the group. The OITE provides funding and works with interns in these programs on an appropriate research group placement.  The OITE sponsors the following SIP cohort experiences:

  • CCSEP for students in community college
  • C-SOAR for college students who have limited access to research opportunities during the school year
  • V-SOAR for college students who are not able to come to an NIH campus
  • GDSSP for master’s students in data science
  • M-SOAR for medical students interested in translational science

Some ICs also sponsor SIP programs - find them on the additional summer programs page.
