My main research focus is in the areas that intersect machine learning, information retrieval, formal representation of knowledge, and automated reasoning with applications in affective computing and cognitive sciences. In this respect, I’m interested in the development of computer systems for mental health and wellbeing.
Also, I have a keen interest in a variety of other scientific challenges and different problems particularly in astronomy and the SETI.
Over the years I have participated in several EU funded research projects and a number of national projects with industry and government. The research projects were concerned with the management of emotion and stress using intelligent computer systems, data mining of EEG time series data, linking of semantic and affective knowledge, and development of affective multimedia databases with tools for multifaceted document retrieval.
Previously, I was a Senior Lecturer in computer science at the Department of Computer Science and Information Technology, Zagreb University of Applied Sciences where I founded the Artificial Intelligence Laboratory.
Before fully joining academia I was employed with domestic and foreign ICT sector companies as a software engineer, project manager, and finally department manager.
I am a reviewer for many respected journals and international conferences, as well as study programs and project proposals for foreign science foundations. Over the years I had the privilege to give several invited lectures, and I enjoy being actively engaged in the popularization of science.
This site showcases some of the research I’ve done, including my CV and a selection of software tools I have developed and which can be freely downloaded for academic purposes, and also (at a moment, unfortunately, a rather diminutive) blog on scientific topics that spark my curiosity.
Research interests: ontologies, knowledge representation, automated reasoning, machine learning, information retrieval, decision support systems, recommender systems, augmented cognition, affective computing, and the semantic web.
