Debra Ellisor

Deb serves as a research biologist in the Biospecimen Science Group at the NIST Biorepository in Charleston, SC. She aims to advance cryopreservation sciences by assessing the effects of pre-analytical variables on biospecimen quality using advanced measurement techniques and developing standardized protocols and methods for sample collection and storage to preserve biospecimen integrity. Deb also assists in maintaining the biorepository in accordance with International Society for Biological and Environmental Repositories (ISBER) best practices to ensure the long-term preservation of the archived collections.

In addition, Deb assists in generating cryogenic reference materials (RMs). Her current projects include the development and production of cryogenic food safety RMs and collaborating with other international National Metrology Institutes to evaluate the effects of reference material production methods on downstream analyses, particularly with regard to food safety and authentication.
