Postdoctoral Fellow (PREP0004328)

PREP Research Associate – CHIPS Funded Project This position is part of the National Institute of Standards and Technology (NIST) Professional Research Experience (PREP) program. The role supports collaboration between NIST and academic institutions on a federally funded CHIPS project, providing technical work that underpins scientific research of the collaboration. Postdoctoral Research Associate: Advanced Optical Metrology for Semiconductor Processes U.S. Citizen Preferred. 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, quantifying partial pressures of deposition precursors and reaction by‑products with microsecond resolution. Key Responsibilities Experimental Leadership: Drive the development and alignment of high‑accuracy EO frequency comb spectrometers. Advanced Optical Metrology: Execute time‑resolved molecular spectroscopy experiments and analyze complex data sets by fitting experimental spectra to molecular databases such as 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. Qualifications 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 The successful candidate(s) for this position will be subject to a pre‑employment background check including education verification. EEO is the Law Vaccine Requirements Johns Hopkins University strongly encourages, but no longer requires, at least one dose of the COVID‑19 vaccine. The COVID‑19 vaccine does not apply to positions located in the State of Florida. We still require all faculty, staff, and students to receive the seasonal flu vaccine. Exceptions to the COVID and flu vaccine requirements may be provided to individuals for religious beliefs or medical reasons. Requests for an exception must be submitted to the JHU vaccination registry. 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. 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: 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 employees 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. #J-18808-Ljbffr Johns Hopkins University
