I am a researcher in the Artificial Intelligence Laboratory. I also hold positions at the University of Primorska and University of Nova Gorica. My research is broadly related to data analysis with an emphasis on topological data analaysis as an application of applied and computational topology. I generally have an interest in both theory and applications. On the theory side, topics of interest are the stability and foundations of persistent (co)homology as well as more recently stochastic topology (the topology of random spaces). On the applications side, my interests are broadly data analysis tools. This includes data analysis, machine learning as well as many other statistical tools. Other areas of interest include visualization and geometric methods. A long time ago I worked in sensor networks and occasionally some new work may pop up. You can find a partial list of my papers below with links, with most of them available on arXiv. For a complete list see my CV.
