Aquatic Ecologist – Research Scientist at Oak Ridge National Laboratory

Jobs Available
Expiration Date: 


The Aquatic Ecology Group (AEG) within the Environmental Sciences Division at Oak Ridge National Laboratory is seeking a scientist to help contribute to its long-term biological monitoring and hydropower research programs. The Oak Ridge Reservation is located within the Ridge and Valley Ecosystem, but also proximate to the Central and Southwestern Appalachian Ecosystems, all of which support among the world’s most diverse flora and fauna. The ORR also is home to Walker Branch, one of the National Ecological Observatory Network (NEON) sites, which provides opportunities for leveraging multi-sensor observation datasets in research. The AEG has conducted considerable research in aquatic toxicology and stream ecosystem responses to contaminant remediation and abatement, but also has a long legacy of research on the environmental effects of hydropower energy and regulatory processes.

Major Duties and Responsibilities

We seek a candidate with combined field-modeling experience working with fish and aquatic invertebrate communities in streams, wetlands, reservoirs, and regulated rivers. However, we are also interested in candidates that desire to pursue experimental research that utilizes the AEG Laboratory. The position requires the use of modern modeling and statistical analysis of fish and invertebrate community data in association with multiple stressors, contaminants, or environmental variation. Work within interdisciplinary research teams is expected, and the successful candidate should be able to conceptualize, organize, and guide multiple tasks and individuals (or sub-modeling components) contributing to larger coordinated efforts, such as integrative frameworks for modeling mercury dynamics in streams. Other work within the group that would support collaborations with the candidate includes geospatial modeling, biogeography, research in urban dynamics, and examination of renewable energy policies.

Acquiring external funding from DOE and non-DOE sources is expected and expanding the scope of the research programs is encouraged. Successful candidates are expected to conduct national and internationally recognized research, obtain additional research funding, publish in scientific journals and technical reports, and present findings at scientific meetings.


Qualifications include a Ph.D. in ecology, environmental sciences, zoology, fisheries, or related areas.  Preference will be given to candidates with post-doctoral research experience and/or existing permanent positions, evidence of strong research productivity, and abilities to support funded research activities. Candidates with strong experience in multivariate statistical procedures, modeling, programming language development, and GIS will be prioritized. Additional preference will be given to candidates with training in both fish and invertebrate communities and ecosystem-level analysis. 

Work Directions and Interfaces

You will report to the Integrated Water-Energy Systems Team Lead in the AEG. You will work in a team environment to support multiple AEG projects, including biological monitoring programs and hydropower projects.  Additional interfaces may include UCOR, TVA, TWRA and/or students/visitors to ORNL.

This position will remain open for a minimum of 5 days after which it will close when a qualified candidate is identified and/or hired.

We accept Word (.doc, .docx), Adobe (unsecured .pdf), Rich Text Format (.rtf), and HTML (.htm, .html) up to 5MB in size. Resumes from third party vendors will not be accepted; these resumes will be deleted and the candidates submitted will not be considered for employment.
