Original job description

What You Will Do

MST-8 is seeking a highly motivated Postdoctoral Research Associate to develop and apply high-rate and impact-testing capabilities that quantify dynamic strength, damage, and failure in metals, polymers, and ceramics.

The postdoctoral researcher will work in a multidisciplinary team integrating dynamic mechanical testing, materials characterization, diagnostics, and modeling. Responsibilities include designing and conducting experiments; operating and improving high-rate testing systems; analyzing wave data; and reporting results. Work may include split Hopkinson pressure bar, gas-gun, RMI, and related tests.

What You Need

Minimum Job Requirements:

Ph.D. in materials science and engineering, mechanical engineering, applied mechanics, physics, or a closely related field.
Demonstrated experimental experience with wave mechanics relevant to dynamic loading, including stress-wave propagation, impedance effects, dispersion, pulse shaping, and data reduction.
Hands-on experience with at least one high-rate testing capability, such as a split Hopkinson pressure bar, gas gun, comparable impact or shock-loading platform.
Experience measuring and interpreting high-strain-rate material response for one or more material classes, including metals, polymers, or ceramics.
Ability to design, execute, document, and analyze complex experiments; communicate results clearly; and contribute reliably to project milestones and sponsor deliverables.
Strong teamwork and communication skills in a safety-conscious research environment.

Desired Qualifications:

Extensive knowledge of gas-gun testing, split Hopkinson pressure bar testing, or a similar dynamic-testing method, including specimen and fixture design, instrumentation, and calibration.
Understanding of relationships among composition, processing, microstructure, and dynamic response, with experience using characterization to interpret mechanical behavior.
Experience with dynamic diagnostics such as strain-gauge instrumentation, high-speed imaging, digital image correlation, velocity interferometry, or other time-resolved measurements.
Experience adapting and building instruments to enable high-rate experiments for metals, polymers, ceramics, or multiphase materials, including attention to impedance mismatch, wave equilibration, and material-specific failure mechanisms.
Experience with computational mechanics, finite-element analysis, wave-propagation modeling, or data-analysis workflows using Python, MATLAB, LabVIEW, or similar tools.

Education:

Ph.D. completed within the past five years or soon to be completed in materials science and engineering, mechanical engineering, applied mechanics, physics, or a closely related field.

Work Environment:

Work Location: The work location for this position is onsite and located in Los Alamos, NM. All work locations are at the discretion of management.

Note to Applicants:

For technical questions related to this position contact Dr. Hi Vo (hvo@lanl.gov) .

For general information to the Postdoc Program go to http://www.lanl.gov/careers/career-options/postdoctoral-research/index.php.

Due to federal restrictions contained in the current National Defense Authorization Act, citizens of the People's Republic of China-including the special administrative regions of Hong Kong and Macau-as well as citizens of the Islamic Republic of Iran, the Democratic People's Republic of Korea (North Korea), and the Russian Federation, who are not Lawful Permanent Residents ("green card" holders) are prohibited from accessing facilities that support the mission, functions, and operations of national security laboratories and nuclear weapons production facilities, which includes Los Alamos National Laboratory.

Where You Will Work

Located in beautiful northern New Mexico, Los Alamos National Laboratory (LANL) is a multidisciplinary research institution engaged in strategic science on behalf of national security. Our generous benefits package includes:

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)
