Job description
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.
The work will entail
This position supports a project focused on developing and validating novel measurement methods for adeno-associated virus (AAV) gene therapy vectors. The primary goal is to address the critical quality control issue of accurately characterizing and quantifying "partially full" viral capsids. The PREP associate will work with a unique set of AAV samples engineered with specifically sized DNA genomes to simulate known filling states. The core of the work involves using advanced microscopy and analytical techniques to establish a quantitative relationship between the AAV genome size, the physical filling state of the capsid, and the capsid's surface hydrophobicity. This research directly supports the NIST mission of advancing biomanufacturing by enabling the development of reference materials and more scalable quality control methods for the gene therapy industry.
Duties
Participating in the production and purification of Adeno-Associated Virus (AAV) samples
Performing characterization of AAV preparations using techniques such as droplet digital PCR (ddPCR), enzyme-linked immunosorbent assay (ELISA), and size exclusion chromatography (SEC)
Performing cryogenic electron microscopy (CryoEM) analysis on AAV samples
Conducting atomic force microscopy (AFM) and chemical force microscopy (CFM) experiments
Analyzing and correlating data from CryoEM, Analytical Ultracentrifugation (AUC), and AFM to establish clear relationships between AAV genome size, filling state, and capsid hydrophobicity
Adhering to all biosafety protocols for materials such as AAVs and human cell lines
Presenting results at internal meetings and potentially at scientific conferences
Publication of results in peer-reviewed journals
Ensuring that experimental results, protocols, and data analysis are thoroughly documented and archived
Required Skills, Expertise, and Qualifications
A Ph.D. in Biological Sciences, Biochemistry, Biophysics, or a closely related field
Proficiency in standard biochemical and molecular biology assays, such as qPCR, ddPCR, ELISA, and protein/nucleic acid quantification
Experience in quantitative data analysis and the ability to correlate results from multiple complex analytical methods
Experience in Transmission Electron Microscopy and Atomic Force Microscopy
Experience in BSL-2 sample handling
Strong oral and written communication skills, evidenced by a track record of publications and/or scientific presentations
Ability to work both independently and collaboratively within a multi-disciplinary team
An Associate at NIST is not a federal employee but collaborates with NIST on research projects of mutual interest and does not work exclusively on NIST mission-related activities. If you have any questions, please contact the International and Academic Affairs Office at . #J-18808-Ljbffr
