My research focuses on three main areas within Old Norse and medieval Nordic studies: Old Norse prosimetrum, particularly in the Icelandic fornaldarsögur (legendary sagas); medieval and early modern Norwegian law; and medieval Faroese ballads.

My scholarly trajectory began with the relationship between prose and poetry in Old Norse literature, especially the prosimetric sagas, before expanding to the transmission, translation, and material history of medieval legal texts, and more recently to Faroese ballad tradition, performance, and oral transmission.

These strands are united by a broader interest in the cultural, historical, and book-historical contexts that shaped medieval Nordic literary and manuscript traditions. Across my work, I examine how texts were composed, transmitted, performed, adapted, and understood within changing social and cultural settings.

My research is interdisciplinary in method, combining philology, literary analysis, and manuscript studies with approaches drawn from legal history, performance studies, and oral tradition research. Through this work, I aim to contribute to a richer understanding of medieval Nordic textual cultures and their afterlives.

I teach and supervise broadly across Old Norse Philology and associated study skills at all levels.
