Her main research areas are the history of private and public art collections, the history of collecting and the art market, provenance research, and portrait painting. She pays particular attention to the collections of the Attems, Szapáry, Wambolt and Strahl families.
She examines the formation and dispersal of collections and transfers of ownership of artworks in the context of auctions, confiscations and political change. By analysing archival sources, she identifies connections between former private collections and present-day museum holdings and clarifies processes of musealisation. Her major published findings include the identification of five paintings from the Strahl collection in the Museum of Arts and Crafts in Zagreb (2018), the reconstruction of post-war transfers of paintings from the collection of the Counts of Attems in Slovenska Bistrica to Slovenian public collections (2021), and a provenance analysis of portraits in the National Museum of Slovenia originating from the portrait galleries of the ducal houses of Liegnitz-Brieg and Schleswig-Holstein (2025 and 2026).
She leads the basic research project Nationalisation and Musealisation of Art Collections in Slovenia in the Light of Provenance Research (running until 31 December 2027), which also involves the Faculty of Arts at the University of Maribor and the National Museum of Slovenia. She also participates in the international project Aristocratic Art Collections in Central Europe, 1795–1939: A Comparative Study (running until 29 February 2028), which places research on Slovenian collections within a comparative Central European framework.
