Company Description

Join us and make YOUR mark on the World!

Are you interested in joining some of the brightest talent in the world to strengthen the United States’ security? Come join Lawrence Livermore National Laboratory (LLNL) where our employees apply their expertise to create solutions for BIG ideas that make our world a better place.

We are looking for individuals that demonstrate an understanding of working in partnership with team peers, who engage, advocate, and contribute to building an inclusive culture, and provide expertise to solve challenging problems.

Job Description

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 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 in the Atmospheric, Earth & Energy Division of the Physical Life Sciences Directorate.


In this role you will
