I am the Digital Collections Librarian at the University of Notre Dame’s Hesburgh Libraries. As a member of the Digital Production and Preservation unit, I’m collaborating across the library on our digitization program, digital collections, and infrastructure to support and share them. I worked previously as the Metadata Librarian at NASA Goddard, through Cadence Group. My MLS specialization is in archives, with a personal concentration on metadata and accessibility. I’ve self-described as a “platypus” because my career has spanned and split the worlds of librarianship and archives without being a traditional form of either and always involving various forms of metadata.

While still in school, I created, a beginner-friendly version of the EAD 2002 tag library. I have created an EAD3 version of the site while continuing support of the previous version. In my time as co-chair of the EAD Roundtable, I led the creation of an official FAQ. I believe in lowering barriers to understanding metadata. Many people who are intimidated by something sounding technical when they don’t consider themselves “techy” can learn if it’s presented in the proper fashion and with an assumption of their competence.
