Postdoctoral Fellow (PREP0004328) - #Faculty

PREP Research Associate CHIPS Funded Project This position is part of the National Institute of Standards (NIST) Professional Research Experience (PREP) program. NIST recognizes that its research staff may wish to collaborate with researchers at academic institutions on specific projects of mutual interest and thus requires that such institutions be the recipients of a PREP award. The PREP program requires staff from a wide range of backgrounds to work on scientific research in many areas. Employees in this position will perform technical work that underpins the scientific research of the collaboration. Research Title Postdoctoral Research Associate: Advanced Optical Metrology for Semiconductor Processes U.S. Citizen Preferred The work will entail: The National Institute of Standards and Technology (NIST) is seeking a driven Postdoctoral Researcher to bridge the gap between fundamental frequency comb spectroscopy and industrial semiconductor fabrication. Joining a multidisciplinary team, you will deploy electro‑optic (EO) frequency combs to perform real‑time, in‑situ mid‑IR spectroscopy of Atomic Layer Deposition (ALD) processes. Your work will directly impact the next generation of microelectronics by quantifying the partial pressures of deposition precursors and reaction byproducts with microsecond resolution. Key responsibilities will include but are not limited to: Experimental Leadership: Drive the development and alignment of high‑accuracy EO frequency comb spectrometers. Advanced Optical Metrology: Execute time‑resolved molecular spectroscopy experiments; analyze complex data sets by fitting experimental spectra to molecular databases (e.g., HITRAN). Computational Analysis: Build and maintain Python‑based tools for signal processing, noise reduction, automated data acquisition, and data analysis. Scientific Communication: Lead the authoring of high‑impact manuscripts and represent NIST's research at international conferences. Education Ph.D. in Physics, Chemistry, Optical Engineering, or a related field. Technical Expertise Proven experience with optical measurements. Direct experience with frequency combs or molecular spectroscopy is highly desirable. Programming Strong programming skills for data analysis and instrument interfacing. Soft Skills A collaborative mindset suited for a fast‑paced, multidisciplinary lab environment and excellent technical writing ability.

Background Checks After receiving a conditional offer, the successful candidate(s) for this position will be subject to a pre‑employment background check including education verification. When deciding whether a candidate's conviction history is job‑disqualifying, the University considers the nature and gravity of the offense, the time that has passed since the conviction, and the nature of the job being sought. EEO is the Law Vaccine Requirements Johns Hopkins University strongly encourages, but no longer requires, at least one dose of the COVID‑19 vaccine. This change does not apply to the School of Medicine (SOM). SOM hires must be fully vaccinated with an FDA COVID‑19 vaccination and provide proof of vaccination status. We still require all faculty, staff, and students to receive the seasonal flu vaccine. Exceptions to the seasonal flu vaccine or COVID‑19 vaccine (for SOM) requirement(s) may be provided to individuals with sincerely held religious beliefs or medical conditions that preclude them from receiving the vaccine. Requests for an exception must be submitted to the JHU vaccination registry. For additional information, applicants for SOM positions should visit and all other JHU applicants should visit The following additional vaccine requirements may apply, depending upon your campus. Please contact the hiring department for more information. The pre‑employment physical for positions in clinical areas, laboratories, working with research subjects, or involving community contact requires documentation of immune status against Rubella (German measles), Rubeola (Measles), Mumps, Varicella (chickenpox), Hepatitis B and documentation of having received the Tdap (Tetanus, diphtheria, pertussis) vaccination. This may include documentation of having two (2) MMR vaccines; two (2) Varicella vaccines; or antibody status to these diseases from laboratory testing. Blood tests for immunities to these diseases are ordinarily included in the pre‑employment physical exam except for those candidates who provide results of blood tests or immunization documentation from their own health care providers. Any vaccinations required for these diseases will be given at no cost in our Occupational Health office. Job Type: Full Time #J-18808-Ljbffr Johns Hopkins University
