**Are you passionate about research and want to utilize state-of-the-art scientific facilities?** **_ Do you enjoy collaborating with dynamic, multidisciplinary research teams?_**

We are seeking a motivated postdoctoral appointee to assist us in research exploring chemical reaction kinetics in the gas phase. The successful candidate will have access to a wide array of state-of-the-art custom chemical physics apparatuses, including an ultrafast optical centrifuge, time-resolved photoionization mass spectrometry, time-resolved laser spectroscopy, and velocity map imaging spectrometers. Using these powerful tools, you will explore fundamental chemistry issues such as: reactions of molecules that are far from equilibrium (e.g., highly rotationally excited), oxidation chemistry producing extremely low-volatility organic compounds, ring-closing reactions that lead to molecular weight growth, or the coupled chemical kinetics of gas phase molecules interacting with a catalytic surface. In all cases our goal is foundational understanding of chemical mechanisms, including identification of reactive intermediates and the pathways that create and consume them.

On any given day, you will:

+ Collaborate with researchers on customization of optical spectroscopies (laser-induced fluorescence, Raman), photoionization mass spectrometry, and supersonic beam velocity map imaging apparatuses.
+ Create proposed reaction intermediates using hyperthermal reactors.
+ Conduct research at Department of Energy light sources using time-resolved photoionization mass spectrometry.
+ Analyze data including spectroscopic fitting and chemical kinetic modeling.
+ Grasp the larger goals of the project, proposing innovative solutions and new directions.

You will be expected to partner with a multi-investigator team, present results at national/international meetings, and publish research in high profile peer-reviewed journals.


+ PhD degree in physics, chemistry, or a closely related field
+ Either (1) significant experience with time-resolved spectroscopy, OR (2) significant experience in chemical kinetics or dynamics experiments probing chemical mechanisms, OR (3) significant experience in heterogenous catalysis.


+ Solid background in charged particle detectors, custom mass spectrometry, and electronics
+ Solid background in laser spectroscopy
+ Solid understanding of gas phase chemical kinetics and dynamics data analysis and interpretation
+ Ability to address complex problems creatively, and to work effectively both independently and in collaboration with other researchers.

Department Description:

The Combustion Chemistry and Diagnostics Department is part of Sandia's Combustion Research Facility (CRF) in Livermore, California, where over 100 scientists, engineers, and technologists conduct basic and applied research to improve our nation's ability to use and control combustion processes efficiently and cleanly. Under the principal sponsorship of the Department of Energy's Office of Basic Energy Sciences, the Combustion Chemistry and Diagnostics Department conducts fundamental experimental, theoretical, and modeling research to develop a foundational understanding of the key chemical processes that underlie the complex mechanisms of combustion. Additional programs investigate the effects of combustion emissions on atmospheric composition and climate. Research areas include chemical dynamics and spectroscopy, theoretical and experimental chemical kinetics, flame chemistry and modeling, and gas-phase and particulate diagnostics development and deployment.

Security Clearance:

This position does not currently require a Department of Energy (DOE) security clearance.

Sandia will conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Furthermore, employees in New Mexico need to pass a U.S. Air Force background screen for access to Kirtland Air Force Base. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause access to be denied or terminated, resulting in the inability to perform the duties assigned and subsequent termination of employment.

If hired without a clearance and it subsequently becomes necessary to obtain and maintain one for the position, or you bid on positions that require a clearance, a pre-processing background review may be conducted prior to a required federal background investigation. Applicants for a DOE security clearance need to be U.S. citizens. If you hold more than one citizenship (i.e., of the U.S. and another country), your ability to obtain a security clearance may be impacted.

Members of the workforce (MOWs) hired at Sandia who require uncleared access for greater than 179 days during their employment, are required to go through the Uncleared Personal Identity Verification (UPIV) process. Access includes physical and/or cyber (logical) access, as well as remote access to any NNSA information technology (IT) systems. UPIV requirements are not applicable to individuals who require a DOE personnel security clearance for the performance of their SNL employment or to foreign nationals. The UPIV process will include the completion of a USAccess Enrollment, SF-85 (Questionnaire for Non-Sensitive Positions) and OF-306 (Declaration of for Federal Employment). An unfavorable UPIV determination will result in immediate retrieval of the SNL issued badge, removal of cyber (logical) access and/or removal from SNL subcontract. All MOWs may appeal the unfavorable UPIV determination to DOE/NNSA immediately. If the appeal is unsuccessful, the MOW may try to go through the UPIV process one year after the decision date.

EEO Statement:

All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, or veteran status and any other protected class under state or federal law.


This postdoctoral position is a temporary position for up to one year, which may be renewed at Sandia's discretion up to five additional years. The PhD must have been conferred within five years prior to employment.

Individuals in postdoctoral positions may bid on regular Sandia positions as internal candidates, and in some cases may be converted to regular career positions during their term if warranted by ongoing operational needs, continuing availability of funds, and satisfactory job performance.
