Here you will find information on a variety of fellowships, training grants, career development awards, and loan repayment programs. Learn about NIEHS-supported predoctoral and postdoctoral training and career development opportunities at universities and other institutions across the country as well as how supplements to existing research grants can be used for training purposes.

Career Development Awards

The purpose of Career Development Awards is to provide support and protected time for an intense, career development experience in the environmental health sciences. Applications must contain both a research proposal and a structured career development plan.


Ruth L. Kirschstein Individual National Research Service Award (NRSA) Fellowships provide an annual stipend, an allowance for tuition and fees, and an institutional research allowance. Applicants must identify a sponsoring institution and an individual who will serve as a sponsor (mentor or supervisor) and who will supervise the training and research experience.

Institutional Research Training

The NRSA program supports predoctoral training, postdoctoral training, and short-term research training experiences for medical students at selected universities across the United States. Institutional NRSA training grants are designed to allow the director of the program to select the trainees and to develop a curriculum of study and research experiences necessary to provide high quality research training.

Loan Repayment Program

The National Institutes of Health (NIH) Extramural Loan Repayment Program is designed to attract health professionals to careers in clinical, pediatric, health disparities, or contraceptive and infertility research. The program offers up to $50,000 per year to repay student loans of scientists, physicians, dentists, and other doctoral level health professionals conducting biomedical or behavioral research funded by domestic nonprofit or government organizations.

NIEHS participates in four of the six programs: Clinical Research (LRP-CR), Pediatric Research (LRP-PR), Health Disparities (LRP-HD) and REACH (LRP-REACH). Read the NIEHS Strategic Plan.


NIEHS supports a variety of supplement awards to help with improving diversity in research, responding to unforeseen events, or taking advantage of emerging technologies.
