Postdoctoral Research Associate - Computer Science/Applied Mathematics
Oak Ridge National Laboratory in Oak Ridge, Tennessee
Date Posted 01/22/2021
Employment Type
Application Deadline Open until filled

Requisition Id 4914 


The Workflow Group at the Oak Ridge National Laboratory (ORNL) seeks highly-motivated scientists to research and develop cutting-edge data reduction technologies. In this role you will work on some of the most challenging scientific problems facing the Department of Energy, creating new algorithms, tools, and technologies to facilitate knowledge discovery.

The rate of data production at next-generation computational facilities enables scientific knowledge discovery but presents a challenge to move, store, and process the data. To maximize their science return, these facilities are forced to make tradeoffs to limit the overall cost of operations. As our facilities evolve, data sizes continue to grow at unprecedented rates, which requires new research and development in data reduction. This position is to focus on novel techniques to deal with this challenge and collaborate with a team of scientists focused on achieving our goals.

Our collaborative work concerns all stages of the scientific life cycle and utilizes computing platforms ranging from the desktop to next generation supercomputers.  Our group works closely with application scientist (e.g. fusion, accelerator, seismology, nuclear), applied mathematicians, and computer scientists. Our group focuses on research and software artifacts in highly cited journals and conferences, helping to enable bleeding edge science at scale.

Our research has resulted in numerous awards and software including an R&D 100 award for the Adaptable I/O System (ADIOS), and the state of the art data reduction software, MultiGrid Adaptive Reduction of Data (MGARD). Our emphasis is on teamwork, and it is important for the applicant to show a strong desire to work within a team, as well as promote her/his research.
