Dr. Mabary’s research interests center on Czech music of the nineteenth and early twentieth centuries, namely the life and works of Antonín Dvořák, Zdeňek Fibich, Bohuslav Martinů, and Vítězslava Kaprálová, as well as the genre of Czech melodrama and on patrons of the arts in nineteenth century United States, namely Jeannette Meyer Thurber. The results of her research in these areas have appeared in publications by Cambridge University Press, Duke University Press, Pendragon Press, Routledge Press, Chronos Verlag (Zürich), and Lexington Books. Her book on Czech melodrama titled Contextualizing Melodrama in the Czech Lands: In Concert and on Stage was released by Routledge in October 2020. She also served as editor of a Festschrift in memory of Michael J. Budds and, in a third collaboration with Routledge, is under contract for a book provisionally titled Jeannette Thurber as Patron and Entrepreneur: Making America's Music. Her chapter on "Women in Czech Opera" is forthcoming in a volume titled A History of Music in the Czech Lands, forthcoming from Cambridge.

Dr. Mabary has also given guest lectures and presentations in numerous venues in Columbia as well as for the Guildhall School for Music and Drama (London), Stanford University, University of California in Santa Barbara, and the Bard Music Festival in New York. In addition, she has presented papers at academic conferences, nationally and internationally, on topics related to the above areas of interest, several of which appear in published conference proceedings. Dr. Mabary has also served in various capacities for professional societies, including as a member of the advisory board for the Kaprálová Society and as chair of the Board of Directors for the Budds Center for American Music, located at the University of Missouri, Columbia.
