Piper Mullins

Program Manager, Pan-Smithsonian Cryo-Initiative
M.A., Pennsylvania State University; M.S., University of Tennessee
Piper Mullins is the program manager for the Pan-Smithsonian Cryo-Initiative (PSCI) and a director-at-large of the International Society for Biological and Environmental Repositories (ISBER). As the program manager for PSCI, she oversees the development of the Smithsonian biorepository network to integrate, standardize, and manage biological frozen collections (aka “biobanks”) and their needs. Mullins brings her information management expertise to collaboratively improve the Smithsonian's biobanking information systems, standards, personnel resources, equipment and space, and the use of biobanks in the research life cycle.
In her early professional career, Mullins collaborated on the development of the Federal Science Repository Service at Information International Associates and managed the digital repository at the University of Tennessee Libraries. She is active in the biobanking industry’s leading forum (ISBER), and currently sits on the Board of Directors and is the vice-chair of the membership and marketing committee.
Mullins received her master's degree in information sciences from the University of Tennessee, where she focused on information management and business analysis for database design. As a graduate student, she reviewed environmental data sharing practices with the University of Texas, Oak Ridge National Lab node of DataOne.
Outside of the frozen collections network which she thinks is the "coolest job," Mullins is an avid dancer and cyclist. She enjoys travelling and hiking, and appreciates the scientists whose research preserves and protects these amazing places and animals.
