General Description

PREP Research Associate

Sensor Science Division Pressure Metrology 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, thus requires that such institutions must be the recipient 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

Fixed-Length Optical Cavity (FLOC) for pressure metrology

The Work Will Entail

Our multidisciplinary team is developing Fixed-Length Optical Cavity (FLOC) pressure standards to cover a broad range from vacuum (< 1 mPa) to high pressure (> 1000 kPa). We are exploring optical cavities machined from a variety of materials including metals, single crystals, and glasses to cover this broad pressure range. We seek a postdoc to help investigate the performance of new optical pressure standards based on (1) low-expansion Invar metal for an ongoing Air Force funded project and (2) ultra-low expansion (ULE) glass for low pressure (vacuum) metrology. A qualified candidate would have a PhD in chemistry, physics, engineering or related fields and have expertise in one or more of the following areas: pressure metrology, optical physics, laser spectroscopy, optical cavities, digital acquisition and instrument control (Labview, Python, etc.).

Key Responsibilities Will Include But Are Not Limited To

  • Improve stability of stable optical cavities by implementing vibrational and temperature control
  • Labview coding for data acquisition and instrument control
  • Analyze data to determine metrics for stability (Allan variance, statistical analysis)
  • Present results at internal group meetings and external meetings and conferences
  • Ensuring that results, protocols, software, and documentation have been archived or otherwise transmitted to the larger organization.

Qualifications

  • PhD in chemistry, physics, engineering or related fields
  • 3 years of relevant experience
  • Demonstrated experience working with lasers and optical cavities
  • Ability to write code to control, operate, and automate data acquisition
  • Familiarity scripting languages for instrument control and data analysis
  • Familiarity with programming languages like Labview, Python, and/or Matlab
  • Strong oral and written communication skills.

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 https://www.hopkinsmedicine.org/coronavirus/covid-19-vaccine/ and all other JHU applicants should visit https://covidinfo.jhu.edu/health-safety/covid-vaccination-information/.

The following additional provisions may apply, depending upon campus. Your recruiter will advise accordingly. 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 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.
