I’m a researcher working on various interdisciplinary topics related to cognition and technology. Examples include computational approaches to semantic analysis of text corpora, applications in MIR (Music Information Retrieval), and in the past, digital preservation, analysis, representation and interpretation of cultural heritage information.

In recent years, my research focuses on music cognition and multimodal interactions present in emotional and visual (color) perception of music. I’m especially interested in how temporary affective states influence individual’s perception of music, and whether mechanisms underlying music cognition can be extended to other areas of affective computing. Together with colleagues from Laboratory for graphics and multimedia (Faculty of Computer and Information Science, University of Ljubljana), we’ve gathered the Moodo dataset ­– currently one of the largest datasets on human emotional and color responses to music. You can take the online survey here.
