Postdoctoral Fellow; PREP

Johns Hopkins, founded in 1876, is America's first research university and home to nine world-class academic divisions working together as one university.

Johns Hopkins University:
Whiting School of Engineering:
Office of Research and Translation

Salary : $82,000-$120,000 a year

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:

Quantum Scattering Calculations of Rates and Ion-Molecule Cross Sections of PFAS Compounds

U.S. Citizen Preferred

• Perform quantum scattering calculations of small PFAS molecules as well as possible replacement compounds for use in plasma etching of semiconductor chips using a suitable code (e.g. UKRMol+).
• Extending the capability of a scattering code to enable project goals.
• Collaborate with other project members to predict ion-molecule cross sections and reaction rates using machine learning models.
• Compare calculated results to results from other calculations and from experiment.
• Potentially interface with CFD modelers to incorporate calculated data into their models.
• Work to develop a knowledge base of the important properties of PFAS molecules for the etch process as a means of guiding the search for replacement compounds.
• Develop software to implement the goals stated above using an appropriate computer language (e.g., Fortran, C/C++, Python).
• Disseminating results through posters/seminars at international meetings and university seminars.
• Ensuring that all results, findings, data, software, etc. are correctly archived and transmitted through appropriate channels.

• Algorithm development, implementation and analysis.
• Scientific and technical programming.
• Computation and analysis of data.
• Presentation of results at internal meetings, and occasional meetings with external stakeholders.
• Publication of results in appropriate journals and publication of data to a web-based database.
• Ensure that results, protocols, software, and documentation have been archived or otherwise transmitted to the larger organization.

• A Ph.D. degree in Chemistry, Physics, Mathematics, Computer Science, Data Science, or a related field.
• 4+ years of relevant experience. Experience in quantum scattering calculations is required.
• Significant course work in one or more of chemistry, physics, mathematics, statistics and/or computer science.
• Ability to program in a modern computational language (e.g., Fortran, C/C++, Python).
• Strong oral and written communication skills.

Salary Range The referenced salary range represents the minimum and maximum salaries for this position and is based on Johns Hopkins University' good faith belief at the time of posting. Not all candidates will be eligible for the upper end of the salary range. The actual compensation offered to the selected candidate may vary and will ultimately depend on multiple factors, which may include the successful candidate's geographic location, skills, work experience, internal equity, market conditions, education/training and other factors, as reasonably determined by the University.
