Ivan has expertise in data analysis, machine learning and data mining, with a focus on data emerging from user behavior on social computing and collective intelligence systems, such as social networks, knowledge sharing systems and e-learning. His current primary research interest is in countering online misinformation.
He has been involved in ten research projects and co-authored over 20 papers, one of which surveyed the methods used by community question answering systems and has received more than a hundred citations. His international research record includes projects with Harvard University and the University of Lugano, Switzerland. He is a member of Slovak.AI and a former member of the Datalys@PeWe research group. He regularly serves as a reviewer for international conferences and journals published by ACM, IEEE, Springer and Elsevier.
He has participated as a data scientist and project lead in many research and industry projects, including a recommender system for ZlavaDna, a smart parking system (zaparkuj.to) and a multibank application developed in co-operation with Unicorn and VUB (a Slovak commercial bank).
