We are seeking a Postdoctoral Research Associate who will support the Computational and Predictive Biology Group in the Biosciences Division (BSD), Biological and Environmental Systems Sciences (BESSD) at Oak Ridge National Laboratory (ORNL).  

The Biosciences Division is focused on advancing science and technology to better understand complex biological systems and their relationship with the environment. BSD has expertise and special facilities in genomics, computational systems biology, microbiology, microbial ecology, biophysics, and structural biology. Computational systems biology research includes methods development and use to analyze large scale omics, greenhouse, field, and clinical datasets to derive insights and hypotheses suitable for further experimental validation and to improve researchers’ ability to further advance understanding of biological systems.

We develop and apply computational methods to explore biological processes at all levels of life systems organization from atomistic to ecological scales. The collection of omics, phenotyping and environmental data, and automation of its analysis and discovery, is becoming increasingly important as the scale of experiments grow and diversify for projects at ORNL including the Center for Bioenergy Innovation, Plant Microbe Interfaces, Secure Ecosystem Engineering and Design, Integrated Pennycress Resilience projects, funded by the DOE, and Biomedical projects, funded by the NIH and VA, and pandemic prevention projects funded by the NSF and other government agencies, among other efforts that also include access to suitable large-scale computational resources.

The Biodiversity and Ecosystem Health Group within the Environmental Sciences Division at Oak Ridge National Laboratory (ORNL) seeks a postdoctoral researcher with an understanding of aquatic biology and chemistry, with a specific focus on contaminant behavior and bioaccumulation in freshwater systems. The successful candidate will work collaboratively with an interdisciplinary team of environmental scientists at ORNL to understand the chemical and ecological factors controlling mercury methylation and bioaccumulation in contaminated aquatic systems and will develop experimental designs aimed at mitigating methylmercury bioaccumulation.

Mercury is one of the most pervasive and widespread contaminants worldwide but the relationship between environmental mercury concentrations, methylmercury production, and mercury bioaccumulation is poorly understood. Because methylmercury bioaccumulation in fish poses both a human health and ecological risk, there is a need to understand both the chemical and ecological drivers of mercury bioaccumulation in aquatic systems. In particular, the candidate will examine the effects of filter feeders on mercury dynamics in stream systems. As keystone species in freshwater ecosystems, freshwater bivalves can drastically affect water quality, habitat, and food web structures, and consequently their presence may also affect mercury bioaccumulation and trophic transfer. The results from this project will be useful in guiding future remediation efforts at Oak Ridge but will also provide a fundamental understanding of the processes governing mercury bioaccumulation in stream systems.
