Description of the Job Duties:

The goal of NIST program in Quantitative Flow Cytometry is to develop reference materials, methodology and procedures to enable quantitative measurements of biological substances such as biological cells, extracellular vesicles, proteins, and nucleic acids. By providing quantitative measurement solutions, we ensure that researchers and clinicians can produce more reliable data, develop better drugs, and provide better treatment to patients in the clinical setting. This individual will support the flow cytometry program under Engineering Biology and Regenerative Medicine by providing assay development and data acquisition and analysis in the area of human adaptive immunity using high-throughput flow cytometry and genomic measurement platform(s). The focus of the work is to probe adaptive immune cells and associated circuitries underlying cell fate decisions and relationship to inflammation caused by infectious diseases, cancer development and therapy.
