Acoustic Signal Processing Machine Learning Postdoc
- Req. Number: IRC139467
- Organization : MPA-11/Materials Synthesis and Integrated Devices
- City, State: Los Alamos, New Mexico
What You Will Do
Los Alamos National Laboratory (LANL) is a multidisciplinary research institution engaged in science and engineering on behalf of national security. The Applied Acoustics Team (MPA-11) is looking for a postdoctoral researcher with strong computational skills and solid background in signal processing and machine learning. We are seeking a highly motivated individual to join a multidisciplinary research team and contribute to the development of a new noninvasive acoustic/ultrasonic characterization and monitoring in complex, noisy systems. This work involves automating the recording, conditioning, and processing of real-world measurements in the time- and frequency-domain; and then developing machine learning algorithms to extract useful information from the signals. The work will also involve some experimental acoustic measurement technique development.
Our current work focuses on applied research for material characterization (solids, liquids, gases), acoustical imaging, nonlinear acoustics, acoustic separation of two-phase systems, detection of corrosion and other defects in structures and monitoring the change in structures over time. The work involves development of new techniques, customized instrumentation, and analysis algorithms. The successful candidate will be expected to contribute to the development of new sensing technologies, patents and publications. There will be opportunities to work in a wide range of areas, to innovate, and present work to sponsors and conferences

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 Policy P701 for applicant eligibility requirements.
Equal Opportunity: Los Alamos National Laboratory is an equal opportunity employer. All employment practices are based on qualification and merit, without regard to protected categories such as race, color, national origin, ancestry, religion, age, sex, gender identity, sexual orientation, marital status or spousal affiliation, physical or mental disability, medical conditions, pregnancy, status as a protected veteran, genetic information, or citizenship within the limits imposed by federal, state, and local laws and regulations. The Laboratory is also committed to making our workplace accessible to individuals with disabilities and will provide reasonable accommodations, upon request, for individuals to participate in the application and hiring process. To request such an accommodation, please send an email to applyhelp@lanl.gov or call (505)-664-6947 opt. 3.
