EPA Fellowship Data Curation and Analysis of Nanomaterial Database

Application Deadline


5/24/2024 3:00:00 PM Eastern Time Zone



*Applications may be reviewed on a rolling-basis and this posting could close before the deadline. Click here for information about the selection process.

EPA Office/Lab and Location: A research opportunity is available at the Environmental Protection Agency (EPA), Office of Research and Development (ORD), Center for Public Health and Environmental Assessment (CPHEA), Public Health & Integrated Toxicology Division (PHITD) in Research Triangle Park, North Carolina.

Research Project: The EPA Office or Research and Development (ORD) is involved in research on the potential environmental effects of engineered nanomaterials. We are building a database containing the results of ORD research on the environmental and biological effects of engineered nanomaterials, which will enable analysis of relationships between the physical and chemical properties of nanomaterials and their environmental actions.  The database structure has been developed and is being populated with data from existing publications regarding the environmental fate, transport, transformations, exposure and toxic effects on ecological or human species.  Other data structures (e.g. graph databases) are being explored. 

Under the guidance of a mentor, the research participant will gain experience in curation of the data, extracting data relevant for the database, and collaborating with a research team to conduct novel analyses of the database. The research participant may conduct research in developing novel applications to analyze the data in the database, and to integrate with external nanomaterial databases such as those in the US and Europe. Under the guidance of a mentor, the research participant will have opportunities to write and co-author manuscripts based on analyses of the database.  Knowledge of nanomaterial environmental and toxicological science will benefit the research participant in understanding relevant parameters to extract from the published literature, as well as conducting novel assessments of the completed database.

Learning Objectives: Research learning objectives may include:

  1. Learning about nanomaterial toxicology
  2. Learning database structure and manipulation
  3. Conducting semantic mapping of nanomaterials to accepted nano ontologies
  4. Conducting statistical analysis of the relationships between nanomaterial properties and their environmental actions including potential toxicity to humans or key environmental species
  5. Learning novel data analysis and display applications and their implementation
  6. Learning data integration strategies and cross-platform mapping strategies
  7. Working with a team to write and edit scientific manuscripts for submission to peer-reviewed journals

Mentor(s): The mentor for this project is Holly Mortensen ( If you have questions about the nature of the research please contact the mentor(s).

Anticipated Appointment Start Date: Spring/Summer 2024.  All start dates are flexible and vary depending on numerous factors. Click here for detailed information about start dates.

Appointment Length: The appointment will initially be for one year and may be renewed upon EPA recommendation and subject to availability of funding.

Level of Participation: The appointment is full-time.

Participant Stipend: The participant will receive a monthly stipend commensurate with educational level and experience. Click here for detailed information about full-time stipends.

EPA Security Clearance: Completion of a successful background investigation by the Office of Personnel Management (OPM) is required for an applicant to be on-boarded at EPA.

ORISE Information: This program, administered by ORAU through its contract with the U.S. Department of Energy (DOE) to manage the Oak Ridge Institute for Science and Education (ORISE), was established through an interagency agreement between DOE and EPA. Participants do not become employees of EPA, DOE or the program administrator, and there are no employment-related benefits. Proof of health insurance is required for participation in this program. Health insurance can be obtained through ORISE.

ORISE offers all ORISE EPA graduate students and Postdocs a free 5 year membership to the National Postdoctoral Association (NPA).

The successful applicant(s) will be required to comply with Environmental, Safety and Health (ES&H) requirements of the hosting facility, including but not limited to, COVID-19 requirements (e.g. facial covering, physical distancing, testing, vaccination).

Questions: Please see the FAQ section of our website. After reading, if you have additional questions about the application process please email and include the reference code for this opportunity.



The qualified candidate should have received a bachelor's, master's, or doctoral degree in one of the relevant fields, or be currently pursuing one of the degrees with completion before the appointment start date. Degree must have been received within five years of the appointment start date.  

Preferred skills/experience:

  • Experience with basic and statistical programming languages, computer science or environmental sciences
  • Interest in discovery of novel relationships between nanomaterial properties and their actions in environmental or biological systems
  • Interest in data integration and analyses using graph databases

Eligibility Requirements


  • Citizenship: U.S. Citizen Only
  • Degree: Bachelor's Degree, Master's Degree, or Doctoral Degree received within the last 60 months or currently pursuing.
