In addition to her activities as a performer, Kathryn is busy as a researcher. She was made a fellow of the Scaliger Institute of the University of Leiden from 2003-2004 where she compiled a catalogue of printed music up until the year 1800, found in the University Library’s collection. This resulted in an exhibition of selected works from the collection entitled: Geluck, geneughd, vermaeck en vreught, Muziekboeken in de Leidse Universiteitsbibliotheek, and an accompanying catalogue written with Ton Koopman. She is also pursuing a PhD at the University of Leiden in the docARTES program, concentrating on the history of the development of the practice of basso continuo in the Dutch Republic, with particular emphasis on an anonymous early 18th century manuscript giving instruction in the art.
Kathryn regularly gives lectures about her research, and contributes to music related magazines and journals such as Harpsichord and Fortepiano magazine and Tijdschrift Oudemuziek.
