Postdoctoral Fellow; PREP

PREP Research Associate

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.

Single molecule biodosimetry

U.S. Citizen Preferred

Development and refinement of new methods for ionizing radiation biodosimetry using single molecule resistive pulse sensors. The scientist will work closely with a multidisciplinary team to design, build, and test novel instrumentation that measures radiation damage to genetic material when subjected to ionizing radiation. Experiments will measure ultrahigh dose rate effects to develop a mechanistic understanding of the FLASH effect for electron, proton, and other novel radiotherapy sources.

Prototype devices will be developed to enable measurements on site (in the field or medical clinic). Single molecule measurements will be validated with conventional systems such as gel electrophoresis and mass spectrometry and results will be cross‑correlated with cell viability assays.

• Preparation of samples for irradiation protocols
• Design, build, and use prototype nanopore devices to measure signatures of DNA damage
• Analyze resistive pulse signals to quantify genetic damage and build models to describe physical and chemical mechanisms of radiation damage
• Present results at internal meetings and occasional meetings with external stakeholders
• Ensure that results, protocols, software, and documentation have been archived or otherwise transmitted to the larger organization

• A doctoral degree in Physics, Chemistry, Nanotechnology or a related field
• 3+ years of experience with biomedical device design, control, and use
• Experience in biosensor development
• Experience with bioelectronic materials
• Experience with electron microscopes including TEM and SEM
• Familiarity with MATLAB software for instrument control and data analysis
• Strong oral and written communication skills

Johns Hopkins University is committed to equal opportunity for its faculty, staff, and students. To that end, the university does not discriminate on the basis of sex, gender, marital status, pregnancy, race, color, ethnicity, national origin, age, disability, religion, sexual orientation, gender identity or expression, veteran status or other legally protected characteristics. The university is committed to providing qualified individuals access to all academic and employment programs, benefits and activities on the basis of demonstrated ability, performance and merit without regard to personal factors or demographic characteristics that are irrelevant to the program involved.

EEO is the Law

Johns Hopkins University strongly encourages, but no longer requires, at least one dose of the COVID‑19 vaccine. However, for School of Medicine hires full vaccination with an FDA‑approved COVID‑19 vaccine and proof of vaccination status is required. All faculty, staff, and students are required to receive the seasonal flu vaccine. Exceptions may be provided for sincerely held religious beliefs or medical conditions that preclude vaccination.

After receiving a conditional offer, selected candidates will undergo a pre‑employment background check, including education verification. The nature and gravity of convictions, time passed since the conviction, and the nature of the job are considered when determining whether a conviction history is job‑disqualifying.
