Postdoctoral Fellow (PREP0004091) Full-time

Postdoctoral Fellow

The National Institute of Standards and Technology (NIST) is seeking a highly motivated postdoctoral researcher with expertise in optical frequency metrology to join the Fundamental Thermodynamics Group. You will contribute to the development of next-generation integrated photonics-based temperature sensors: chip-scale devices designed to transform precision thermometry. The role focuses on laser-based interrogation, frequency locking, and frequency comb-enabled measurement techniques for field-deployable precision sensing. The position provides the opportunity to gain advanced experimental skills and research experience valuable for careers in academia, industry, or national laboratories. Based on the candidate's experience, the position can be extended to a research scientist. Salary levels vary with experience.

Temperature is one of the most widely measured physical properties and is essential across nearly all scientific and technological fields. To meet the growing need for precise, accurate, and field-deployable temperature metrology, our team is developing an on-chip photonic thermometer that functions as both a sensor and a deployable primary temperature standard. This self-calibrated device offers a transformative alternative to legacy resistance thermometers and has the potential to redefine how temperature is realized and disseminated worldwide.

Key responsibilities include the development of advanced photonic readout methods for sensing applications, implementation and optimization of experimental setups for photonic and thermometric measurements, and data analysis, modeling, and interpretation to evaluate device performance and guide design improvements.

Opportunities for the candidate include working on cutting-edge nanophotonics research with real-world metrology impact, shaping new research directions and contributing to emerging programs, collaborating with a multidisciplinary team of scientists and engineers, submitting invention disclosures and patent applications, and publishing in leading scientific journals and presenting at technical conferences.

Qualifications include a Ph.D. or equivalent experience in natural sciences, engineering, or related fields, innovative thinking and strong experimental skills, ability to work both independently and collaboratively, effective written and oral communication skills, and prior hands-on experience in laser spectroscopy, frequency locking and stabilization, and frequency combs. U.S. citizenship is strongly preferred. The position is full-time (40 hours/week) and is located at NIST Gaithersburg, Maryland, with a 1-year appointment, with possible extension. Applications are accepted until filled. Contact Dr. Nikolai N. Klimov at nklimov@nist.gov.
