What You Will Do
Come join the best and brightest minds in the world at one of the most innovative and creative multidisciplinary research institutions. The Center for Aerosol-gas Forensics (CAFE) team at Los Alamos National Laboratory seeks an intellectually agile experimental postdoctoral researcher to validate next-generation nuclear fallout models.
You will lead laboratory measurements on fallout mimics and analyze the resulting data to validate microphysical models. Working alongside modelers, you will connect these measurements to high-temperature particle nucleation modeling and large eddy simulation of nuclear test data.
This research leverages CAFE's state-of-the-art particle microphysics and cloud chamber laboratory to generate the data that anchors robust fallout transport codes for nuclear deterrence and national security.
You will join the Modeling and Observations of Earth Systems Group within the Earth and Environmental Sciences Division, a collaborative, experimentally driven team that tackles strategic national security challenges. Our atmospheric science spans weapons effects, energy advancement, and environmental stewardship, with active collaborations across defense agencies and national laboratories.
What You Need
You will be an experimentalist with a background in aerosol measurements and atmospheric science, and a strong interest in data-driven experiment-model validation.
The role centers on running cloud chamber experiments, generating aerosol mass spectrometry data, and using Python to analyze those measurements and validate microphysical models.
You will work both independently and collaboratively within a multidisciplinary team of experimentalists and modelers, publishing in peer-reviewed journals and presenting at national
Minimum Job Requirements:

Clearance: Q (Position will be cleared to this level). Selected applicants will be subject to a background investigation conducted by or on behalf of the Federal Government, and must meet eligibility requirements* for access to classified matter. This position requires a Q clearance, and obtaining such clearance requires US Citizenship except in extremely rare circumstances. Dependent upon the position, additional authorization to access classified information may be required, which may or may not be available to dual citizens. Receipt of a Q clearance and additional access authorization ultimately is a decision of the Federal Government and not of Triad.
- Eligibility requirements: To obtain a clearance, an individual must be at least 18 years of age; U.S. citizenship is required except in very limited circumstances. See DOE Order 472.2 for additional information.
No Clearance: Position does not require a security clearance. Selected candidates will be subject to drug testing and other pre-employment background checks.
HRP: This position is subject to the requirements of the DOE Human Reliability Program as specified in 10 Code of Federal Regulation, Part 712, §712.11. These requirements include on going drug and alcohol testing, as well as periodic medical and psychological evaluations.
426.2A: This position is subject to DOE Order 426.2A, Personnel Selection, Training, and Qualification Requirements for DOE Nuclear Facilities, which establishes entry-level requirements to ensure candidates selected for specific positions can successfully perform the requirements of the job.
New-Employment Drug Test: The Laboratory requires successful applicants to complete a new-employment drug test and maintains a substance abuse policy that includes random drug testing. Although New Mexico and other states have legalized the use of marijuana, use and possession of marijuana remain illegal under federal law. A positive drug test for marijuana will result in termination of employment, even if the use was pre-offer.
