Meet the Founder
Katherine (Hyun-Joo) Mooney, PhD, is a historian with over a decade of professional experience in research, writing and public storytelling. Before founding Saseo.Studio, she created and managed content for a major government website that received over 90 million views in 2025.
Her work spans peer-reviewed scholarship and public-facing writing. She has a forthcoming article on Zambian rock music in the 1970s in The Journal of Popular Music Studies (March 2026). Her writing has appeared on War.gov, Army.mil, Army History, Truthdig, Africa Is a Country and in many other publications. She previously worked at the U.S. Army Center of Military History, contributing to the research and publication of official history volumes.
Katherine brings hands-on production skills to Saseo.Studio, including archival digitization, oral history interviews, content management, social media content creation and design work. She founded Saseo.Studio to help companies and individuals build archives and translate their histories into clear, compelling public narratives.
Saseo.Studio builds archives to be used, shared and sustained.
The Saseo.Studio logo is inspired by traditional Korean seal stamps (도장), which were used to sign documents, mark authorship and authenticate records.
The word saseo (사서) refers both to a historical record keeper or archivist and to the Four Books, a foundational collection of classical texts that shaped scholarship and moral thought in East Asia.
Together, the seal stamp and the word 사서 reflect Saseo.Studio’s commitment to careful documentation, intellectual tradition and long-term stewardship of stories and archives.
