Urban-Scale Atmospheric Modeling- Postdoctoral Researcher

Lawrence Livermore National Laboratory
Livermore, CA 94550

Join us and make YOUR mark on the World!

Come join Lawrence Livermore National Laboratory (LLNL) where we apply science and technology to make the world a safer place; now one of 2020 Best Places to Work by Glassdoor!

We have an opening for a Postdoctoral Researcher to conduct research using state-of-the-art atmospheric models for a variety of applications, which include ultra-high resolution modeling in urban and complex areas, outdoor-indoor coupled systems, as well as fate and transport for the National Atmospheric Release Advisory Center (NARAC, see https://narac.llnl.gov). You will work with a multidisciplinary team of scientists, engineers, technicians, and project managers to develop and apply new capabilities for emergency response, hazardous transport, and national security purposes. This position is with the Atmospheric Science Research and Applications Group of the Atmospheric, Earth & Energy Division.

Essential Duties
- Conduct research in and development of one or more of the following areas: atmospheric modeling, large-eddy simulations of hazardous material transport, urban-scale modeling and outdoor-indoor coupled systems.
- Design, implement, and analyze techniques in one or more of the above areas.
- Organize, analyze, and present data from research.
- Develop, validate and apply computer models of urban-scale and complex terrain atmospheric transport, diffusion, deposition and effects of hazardous material.
- Analyze model and observational datasets relevant to the NARAC, and/or urban-scale system applications.
- Document research by publishing papers in peer-reviewed journals and present technical results at scientific conferences.
- Pursue independent (but complementary) research interests and interact with a broad spectrum of scientists internally and externally to the Laboratory.
- Collaborate with others in a multidisciplinary team environment to accomplish research goals.
- Perform other duties as assigned.

- Recent PhD in in atmospheric science; mechanical, civil or environmental engineering, or a closely related field.
- Experience in one or more of the following areas:urban dispersion modeling, atmospheric science, turbulence and diffusion modeling, computational fluid dynamics, large eddy simulation, indoor-outdoor models, nuclear/radiological sources and effects, regional atmospheric flow, atmospheric boundary layer, atmospheric chemistry, aerosol science, field data analysis, and health physics.
- Experience with numerical methods and model development.
- Familiarity with programing languages including Fortran, Python, MATLAB.
- Experience conducting research in atmospheric science, engineering or closely related field, and travel as required to collaborate with researchers.
- Experience with urban-scale simulation and expertise in one or more of the following areas: atmospheric transport and dispersion, indoor-outdoor systems, aerosol science, or large-eddy simulation.
- Experience with large model and observational datasets, modern programming environments, and visualization techniques.
- Proficient verbal and written communication skills, as evidenced by published results and presentations.
Desired Qualifications
- Experience with data science, machine learning, uncertainty quantification, ensembles, statistical analysis, microphysics or atmospheric boundary layer turbulence, nuclear/radiological sources and effects.
- Familiarity with GPU programming, MPI/ OpenMP for supercomputing.

Pre-Employment Drug Test: External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test. This includes testing for use of marijuana as Federal Law applies to us as a Federal Contractor.

Security Clearance: This position requires a Department of Energy (DOE) Q-level clearance.

If you are selected, wewill initiate a Federal background investigation to determine if youmeet eligibility requirements for access to classified information or matter. In addition, all L or Q cleared employees are subject to random drug testing. Q-level clearance requires U.S. citizenship. If you hold multiple citizenships (U.S. and another country), you may be required to renounce your non-U.S. citizenship before a DOE L or Q clearance will be processed/granted.

Note: This is a 2 year Postdoctoral appointment with the possibility of extension to a maximum of 3 years. Eligible candidates are those who have been awarded a PhD at time of hire date.
