Postdoctoral Fellow (PREP0004187)

Johns Hopkins, founded in 1876, is America's first research university and home to nine world-class academic divisions working together as one university. Salary $85,447 - $88,500 Johns Hopkins University: Whiting School of Engineering: Office of Research and Translation Description PREP Research Associate This position is part of the National Institute of Standards and Technology (NIST) Professional Research Experience Program (PREP). NIST recognizes that its research staff may want to collaborate with researchers at academic institutions on specific projects of mutual interest and, therefore, requires those institutions to be recipients of a PREP award. The PREP program involves staff from a wide range of backgrounds conducting scientific research across various fields. Individuals in this position will perform technical work supporting the collaboration's scientific research. Research Title Vibrational micro-spectroscopist for detecting and identifying irregularly shaped particles (U.S. Citizens Preferred) U.S. Citizen Preferred The work will entail The Materials Measurement Laboratory of the National Institute of Standards and Technology (NIST) is seeking qualified persons (U.S. Citizens preferred) to develop analytical tools needed to monitor and characterize micro and nanoplastic (MNP) particles. The applicant will use commercial optical photothermal infrared (OPTIR) microscopy and other vibrational spectroscopy and imaging methods to improve identification of irregularly shaped particles less than 10 μm. Key Responsibilities will include but are not limited to: Develop methods using OPTIR microscopy to characterize nonspherical polymeric particles ( Design and evaluate experimental systems to examine signal origin, measurement artifacts, and depth-dependent compositional relationships in OPTIR with pristine and chemically modified control samples. Develop performance metric benchmarks for OPTIR measurements that can be used for evaluating data and method transferability to widely used IR-based and Raman techniques. Contribute to NIST efforts for evaluating and characterizing crystallinity, molecular structure, and composition of candidate reference materials, which include irregularly shaped, polymeric particles and asymmetric material arrays. Employment Terms This opportunity is to be an associate researcher in the NIST Materials Measurement Science Division for a term of 1 year, with options to renew. Associate researchers are NOT Federal Employees, but they work alongside NIST researchers and with NIST’s world-class instrumentation. Relocation expenses will not be provided. U.S. Citizens hired into associate positions may have the opportunity to seek longer term Federal Employment. Qualifications Ph.D. degree in physical sciences, materials engineering, or chemical engineering. Expertise in high-resolution chemical mapping of materials and tissues with OPTIR (preferred), Raman, or IR microspectroscopy. Expertise in multivariate statistical methods used for evaluating vibrational spectroscopy data (OPTIR preferred), including chemometrics, adapted ML tools, or other applied methods. Demonstrate successful participation as a member of multidisciplinary research teams.
