Research Fellowships

NSF Graduate Research Internship Program (GRIP) / Graduate Research Fellowship Program (GRFP)

Application deadlines are managed by NSF. GRIP/GRFP Deadlines are May 6 and December 4

(Due to COVID-19) GRIP is On Hold Until Further Notice. NSF/GRFP INTERN Program is Still Active - Info on GRFP INTERN Below.

The National Science Foundation has created the Graduate Research Internship Program (GRIP)/Graduate Research Fellowships Program (GRFP) for graduate students to complete internships at federal agencies. The NSF and United States Environmental Protection Agency collaboration is designed to encourage, develop, and facilitate collaborative professional development and research opportunities for NSF Graduate Research Fellows (GRF). Here at EPA, GRIP/GRFP students can grow professionally with a rewarding research experience and receive mentoring from our researchers, all while focusing on the protection of human health and the environment.

Interested students should start by identifying an EPA GRIP/GRFP opportunity and contacting the lead researcher to discuss internship goals. The student may collaborate with the researcher to develop a project plan, per NSF Instructions (PDF)(5 pp, 607 K, April 16, 2018). The student will prepare his/her own GRIP/GRFP application to request supplemental funding from NSF. GRIP/GRFP is open only to NSF Graduate Fellows, recipients of the Graduate Research Fellowship Program (GRFP) award.  

  •  Learn more about the NSF application process and eligibility requirements.
    • All GRIP/GRFP awards are subject to the availability of funds, merit review, and acceptance by both the National Science Foundation and NSF's partner agencies (EPA).
    • A Fellow may submit one (1) application per partner agency and may apply to a maximum of two (2) partner agencies for each submission deadline. 
    • NSF awards GRIP/GRFP internship allowances to Fellows based on a twice-yearly competition.

  • Air Research

    Topic: International Household Energy Research
    The student will have the opportunity to work with a team of researchers in a leading laboratory in partnership with a worldwide initiative to address global health and environmental problems associated with household energy.  The student will learn about laboratory evaluation of air pollutant emissions, data analysis, and publication of results.  Experience with VBA or other programming language would be a plus.

    Topic: Performance Evaluation of Low-Cost Air Quality Sensors
    The objective of this opportunity is to evaluate the performance of a low-cost sensor for ambient air quality measurement.

    Topic: Fundamental UV/IR Reference Spectra Analysis and Evaluation
    The reference spectra used for pollutant emissions quantitation by typical spectral absorption analyzers are based on empirical derivation from gas standards where possible. However, in the absence of quality reference gas standards, they are many pollutants reliant on theoretical spectra (e.g., HITRAN, PNNL, etc) generated by computational means based on multiple spectroscopic parameters. The quantitative quality and appropriateness of these modeled spectra in the absence of empirical confirmation is an uncertainty for EPA relating to the quality of regulatory emissions measurements.

    Topic: Combining Measurements and Modeling to Better Understand Ammonia Air-Surface Exchange Processes
    The objective of this project is to characterize the sensitivity of EPA’s bi-directional ammonia flux model to inputs of meteorology, air concentrations and biogeochemistry, focusing on the role of soil and vegetation compensation points.

    Topic: Quantifying the Consequences of Spatio-temporal Dynamics of Mangroves Forests in the Provision of Ecosystem Goods and Services
    Mangrove forests provide important ecosystem goods and services to the world’s dense coastal population and support important functions of the biosphere. The forests are under threat from both natural (e.g. typhoons, sea-level rise) and anthropogenic forces (rapid economic development, population growth). The loss of these ecosystems can lead to the loss of critical functions of mangroves including coastal protection, carbon sequestration and biodiversity—thus threatening the resiliency and vitality of coastal social-ecological systems. However, our scientific understanding is limited in regards to the rates, patterns and causes of changes to mangrove forest cover and their impact in providing ecosystem goods and services. The proposed research aims to examine dynamics of mangrove forests and associated change in ecosystem good and services of from 1985 to present.

  • Sustainable and Healthy Communities Research

    Topic: Assessing Health Risks Related to Waste Disposal Sites Impacting Alaska Tribes
    The management and disposal of solid waste is one of the greatest challenges for many remote Tribes. Due to insufficient geological conditions, remote location, inability to export, and/or high waste processing costs, proper waste disposal to minimize risk to resident populations is extremely difficult. These described waste conditions are common for Alaska Tribes. Roughly three-quarters of Alaskan Village disposal sites are within one mile of homes and up to 30 percent are within one-quarter mile of homes. Most Alaska Tribes rely on their traditional way of life, for example, gathering water from traditional sources. Health impacts can result from inhalation and ingestion exposures to contaminated air and drinking water, as well as from spread of disease via insects, birds, and other vectors.

    Topic: Assessing soil responses in recently restored coastal salt marshes
    Ongoing restoration projects in Rhode Island are testing different methods to build coastal marsh resistance and resilience. In this project, the student will examine the soil responses to hydrological restoration (i.e., runnel creation) and thin layer placement of dredged materials to coastal marshes. Restored marshes are hypothesized to have increased resistance to erosion and improved resilience to flooding events and storm surges. Soil parameters of pH, bulk density, moisture, salinity, oxidation-reduction status, and shear strength between reference marshes and restored sites will help predict trajectories of change in the coastal areas. The restoration monitoring will be carried out through partnerships and engagement with community, state, and federal groups.

    Topic: Flood Induced Contaminants Fate and Transport and Exposures Risk in Vulnerable Communities
    Recent published studies have shown that high-flow events can induce undesired transport of contaminated sediments into surrounding areas (e.g., rivers, water reservoirs, private wells, etc.) and result in elevated levels of contaminants in the vicinity of Superfund sites. This research opportunity takes a system approach to focus on environmental fate/transport of regulated or emerging contaminants due to flood (drought) and its near-field exposures.  The research results can be submitted for peer-review publications.  The results could be applied to contaminant clean-up guidelines for vulnerable communities.
