Requisition Id 16260 **Overview:** The Biodiversity and Ecosystem Health group within the Environmental Sciences Division (ESD) at Oak Ridge National Laboratory (ORNL), is seeking an aquatic ecologist focused on fisheries and data science to support research on the interactions between energy infrastructure, especially hydropower systems, and aquatic ecosystems. This position focuses on applying advanced geospatial, statistical, and quantitative approaches to fisheries, hydrological, and ecological data to improve understanding of how hydropower operations influence fish populations, movement, survival, and habitat use. The successful candidate will work within a multidisciplinary team of biologists, hydrologists, engineers, and data scientists, contributing to nationally relevant research that informs sustainable hydropower development, environmental compliance, and energy–ecosystem decision making. Environmental Sciences Division is an interdisciplinary research and development organization with over 60 years of achievement in local, regional, national, and international environmental research. Our vision is to expand scientific knowledge and develop innovative strategies and technologies that will strengthen the nation’s leadership in creating solutions to help sustain the Earth’s natural resources. Our scientists conduct research, develop technology, and perform analyses to understand and assess responses of environmental systems at the environment-human interface and the consequences of alternative energy and environmental strategies. With the aim of enhancing national energy security, the Biodiversity and Ecosystem Health Group actively develops scientifically robust technologies designed to mitigate ecological impacts. These innovations are created through rigorous scientific methods, incorporating interdisciplinary approaches that span ecology, hydrology, biology, and environmental engineering. The practical tools and technologies developed are geared toward
