EPA Office/Lab and Location: A research opportunity is currently available at the Environmental Protection Agency (EPA), Office of Research and Development (ORD), Center for Environmental Solutions and Emergency Response (CESER), Land Remediation and Technology Division (LRTD) located in Cincinnati, Ohio.

Research Project: The assessment of impacts across a chemical’s life-cycle is essential to protect human health and the environment. Therefore, it is critical to track the flow of chemicals, including releases, during manufacturing processes, product use, and end-of-life (EoL) scenarios. Data engineering approaches coupled with multi-criteria decision-making models can greatly enhance chemical assessment activities related to chemical safety and sustainability.  

A research opportunity is currently available to learn how to design, model, and assess pathways and technologies to help transform chemical manufacturing and use from the traditional linear production paradigm (raw material extraction, manufacturing, usage, and disposal) to an emerging emphasis on circular economy. The selected participant may broadly research manufacturing, use, recycling, recovery, and disposal options for chemical substances and their products. 

The selected participant’s understanding of the various manufacturing, use, and EoL options for chemicals and products may help develop computational frameworks that quantify chemical flows and releases throughout the economy, including consumption. In collaboration with EPA Scientists, the research participant will evaluate and determine chemicals present in manufacturing, usage, recycling, and disposal options; and prepare peer-reviewed manuscripts and reports from the conducted research. 

Learning Objectives: This training opportunity will provide the research participant with state-of-the-art knowledge and networking opportunities to exchange experiences and information in estimating chemical flows and releases during various scenarios for manufacturing, use, and end-of-life management.

Mentor(s): The mentor for this opportunity is Gerardo Ruiz-Mercado ( If you have questions about the nature of the research please contact the mentor(s).
Anticipated Appointment Start Date: May 2022. 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 up to three or four additional years 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).
