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:
Computational Postdoc for 4D-STEM Electric Field Metrology
The work will entail:
The goals of the position are to develop code for near real time visualization of 4D scanning transmission electron microscopy (4D-STEM) data and to optimize electron phase retrieval from a variety of 4D-STEM data formats. The associate will assess the format of data sets from different instruments and determine optimal procedures for data handling. They will research methods to enhance the sensitivity and accuracy of the software tools. They will contribute to data evaluation and interpretation to enhance the sensitivity and accuracy of the 4D-STEM electric field measurement and to optimize the strategic directions of the project. They will organize and present data analysis and modeling software in ways that are clear and useful to team members and project managers.
Key responsibilities will include but are not limited to:
- Develop code to intake 4D-STEM data from multiple system formats and implement various methods of phase retrieval in python or similar; test and optimize phase retrieval method.
- Develop software to interrupt STEM system data flow and generate real time visualization of STEM data.
- Develop code to simulate 4D-STEM data and the influence of collection conditions on the data and phase shift retrieval.
- Simulate expected variations in 4D-STEM data and phase shift with changes in materials.
- Communicate and collaborate with team members. Present and publish results as appropriate.
Qualifications
- A PhD in Materials Science and Engineering, or a related field.
- Three or more years of experience programming with Python or similar.
- Experience with computational modeling of materials systems.
- Ability to develop prototype tools for analysis of diffraction data.
- Familiarity with multiple programming languages.
- Experience with large data analysis.
- Strong oral and written communication skills.
