Postdoctoral Researcher in Computational Kinetic Theory
- Req. Number: IRC139815
- Organization : Applied Mathematics And Plasma Physics/T-5
- City, State: Los Alamos, New Mexico
What You Will Do
We are seeking qualified candidates to join the Theoretical Division (T-Division) at Los Alamos National Laboratory. T-Division offers a dynamic and intellectually stimulating environment that promotes interdisciplinary collaboration in support of the Laboratory's strategic basic research and national security missions. Within T-Division, the Applied Mathematics and Plasma Physics Group (T-5) conducts cutting-edge research in areas such as novel algorithms, numerical methods, and theoretical modeling. Applications span a wide range of fields, including fusion and high energy density science, space plasma physics, astrophysics, numerical analysis, machine learning, computational imaging, optimization, artificial intelligence, environmental science, and the modeling of critical infrastructure systems such as gas pipelines and electrical grids.
The selected candidate will work closely with mentors and other collaborators to advance a novel formulation of kinetic equations-referred to as conditional kinetics (arXiv:2410.20106)-across various domains, including plasmas, neutrons, photons, phonons, and gases to develop a new paradigm for multiscale and multiphysics coupled kinetic simulations. This work will involve developing new numerical methods for solving these equations. A strong background in plasma physics, astrophysics, nuclear engineering, or applied mathematics is preferred, particularly with experience in numerical algorithms for solving hyperbolic or parabolic partial differential equations (PDEs). A demonstrated ability-and eagerness-to acquire new skills and adapt to emerging research areas is essential. The initial appointment is for two years, with the possibility of a third-year extension contingent on performance and available funding.

§ PPO or High Deductible medical insurance with the same large nationwide network
§ Dental and vision insurance
§ Free basic life and disability insurance
§ Paid childbirth and parental leave
§ Award-winning 401(k) (6% matching plus 3.5% annually)
§ Learning opportunities and tuition assistance
§ Flexible schedules and time off (PTO and holidays)
§ Onsite gyms and wellness programs
§ Extensive relocation packages (outside a 50 mile radius)
Additional Details:
Directive 206.2 - Employment with Triad requires a favorable decision by NNSA indicating employee is suitable under NNSA Supplemental Directive 206.2. Please note that this requirement applies only to citizens of the United States. Foreign nationals are subject to a similar requirement under DOE Order 142.3A.
No Clearance: Position does not require a security clearance. Selected candidates will be subject to drug testing and other pre-employment background checks.
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.
Internal Applicants: Regular appointment employees who have served the required period of continuous service in their current position are eligible to apply for posted jobs throughout the Laboratory. If an employee has not served the required period of continuous service, they may only apply for Laboratory jobs with the documented approval of their Division Leader. Please refer to Policy P701 for applicant eligibility requirements.
Equal Opportunity: Los Alamos National Laboratory is an equal opportunity employer and supports a diverse and inclusive workforce.
