Job Opportunities

BACKGROUND INFORMATION

The National Institute of Standards and Technology’s (NIST’s) Material Measurement Laboratory (MML) serves as the national reference laboratory for measurements in the chemical, biological and material sciences through activities ranging from fundamental and applied research, to the development and dissemination of certified reference materials, critically evaluated data, and other programs and tools to assure the quality of measurement results. One of the program areas where MML has significant research efforts in the field of forensic science, specifically drug chemistry.  A major project within this research area is the development of methods and tools for next generation chemical analyses to provide to the community.  A key technology for next generation analysis is direct analysis in real time mass spectrometry (DART-MS) which has been shown to be to detect a number of forensically relevant compounds including drugs of abuse, explosives, chemical warfare agents, lotions and lubricants, and toxic industrial chemicals (TICs) in seconds.  While the technology shows promise, especially for forensic analysis of seized drugs, the data analysis process is currently cumbersome and lacks key features needed by the community. 

To help address the data analysis limitations, work in MML has been ongoing on the development of an update DART-MS spectral database (DBB) and new DART-MS search algorithms (DST).  With the database and search algorithm, forensic chemists will be able to analyze their data more accurately, more efficiently, and with increased confidence over traditional programs.  The intent is to bring the database and search algorithm from a research tool to something that is implementable by the forensics community through the development of a user-friendly interface and additional features or functions. These features will include report generation functionalities, commenting capabilities, and additional functionalities that will be identified through iterative feedback with four collaborators within the forensics community.  Iterative updates to the software will be expected throughout the process with a finished version of the software completed by the end of the award. It is also expected that technical documentation will be developed to accompany the software.

SCOPE

In collaboration with NIST staff, the awardee will be working to improve the newly implemented NIST DART-MS Search Tool (NIST DST). In particular, the focus is on developing auxiliary functionality that improves the overall usability of the NIST DST, while NIST Scientists continue to optimize the underlying search functionality. Additionally, the documentation must be drafted to aid the use and continued development of the DST. The NIST DST is an R Shiny application and is intended for use across multiple operating systems. The current version of the NIST DST can be found here: https://github.com/asm3-nist.

GOALS

1. Improve user interface with ‘Reporting’ functionality.

A preliminary version of the NIST DST has been developed as an R Shiny Application. Using this codebase as a starting point, the awardee will improve the usability of the NIST DST by refining the user interface and developing a ‘Reporting’ function to the specifications recommended by NIST staff and collaborators. Software and supporting document updates will be periodically shared with NIST collaborators.

2. Incorporate user feedback.  

Feedback about software and supporting document updates will be solicited and collated by NIST staff and provided to the awardee as updated specifications. The awardee will refine the NIST DST accordingly.

3. Support implementation of additional functions.

NIST staff will be optimizing the search functionality of the DST. The awardee will support the implementation of the updated functions into the main DST codebase.

Development Process

NIST staff will be making code changes at the same time as the participant.  Git is used for version control (NIST uses an internal GitLab instance as the source repo).  Both the participant and NIST staff shall commit code changes under their respective accounts. 

Software will be developed continuously through the duration of the award with regular meetings to discuss progress. Additionally, there will be three major checkpoints where a clone of the software will be shared with collaborators to solicit feedback.

PREP Candidate

NIST is looking for a Software Developer with a bachelor’s degree or equivalent; minimum of 2 years’ experience in the R programming language; use of the R Shiny framework; and experience in software development and design. It will be useful if this person has experience working with chemical data and experience working in a research and development environment.

Position: The position can be full-time or part-time, depending on the circumstances and skills of the successful  candidate.

Salary:  Salary will be commensurate with experience.

Candidates should send their CV to  edward.sisco@nist.gov or arun.moorthy@nist.gov

The Georgetown/NIST Professional Research Experience Program seeks a post-doc to work on the following topic:

High-Sensitivity Infrared Microscopy for Live Cells
Currently, no imaging method is capable of concentration mapping with chemical identification despite the extensive practice of optical characterization of cells. The new NIST-developed infrared (IR)  imaging strategy will lead to label-free, in-situ cytometry of critical cell characteristics from viability to identity, and the results will be system-independent and universally reproducible. Based on recent breakthroughs in IR spectral engineering, our proposed IR absorbance imaging will eliminate the strong water absorption contribution and see the molecular signatures of biological samples in water or in their natural environment. The new IR spectral engineering technique has been demonstrated for high sensitivity characterization of protein structures. We also propose to apply this advanced spectroscopy method to noninvasive monitoring of protein drugs production.

Benefits to NIST

The SI-traceable IR imaging concept is a revolutionary advancement for the in-situ quantitative chemical imaging of all cell biology and cell therapeutics and has the potential to advance engineering biology, biomanufacturing, cancer research, and forensics.Success of this high-risk but high-impact project, leveraged by NIST’s unique strengths in hyperspectral imaging, optical cell measurements, microfluidics, and machine learning, will advance the quantitative cell metrology and boost measurement assurance directly in cell therapeutics and regenerative medicine and more broadly biomanufacturing, engineering biology, and pharma industries.

The Biomaterials Group has been developing new vibrational spectroscopic technologies aimed for characterizing protein drugs. This is directly related to the NIST strategic program of Biomanufacturing Initiatives. Success in this project requires expertise in both vibrational spectroscopy and bioimaging, which are not available easily. This work enables NIST to address the needs of stakeholders (biomanufacturing and biomedical industries and FDA) for advanced analytical tools with higher sensitivity and specificity. In addition, this work outcome can be applied to various process analytical technology (PAT) approaches during the development and production of protein drugs, vaccines, adjuvant-drug-conjugate drugs, and other medicinal products.
