Brief bio

Research topics

I am interested in theory and practice of statistical modeling and pattern mining in various data. Currently, I am working mostly on a novel framework for pattern mining based on subjective interestingness in data analysis. As a side project I am active in analysis of natural language corpora and corpus linguistics. I have also been working on (interactive visual) graph mining and social network analysis on web data and citation networks. More generally, I am interested in mining interesting/surprising patterns in transactional, sequential, relational data, and graphs, as well as in text mining, natural language processing, statistical significance testing, and maximum entropy modeling.


I am a Postdoc at the Data Science Lab at Ghent University, working with Prof. Tijl De Bie on the FORSIED project. Previously, I was a Research Associate at the University of Bristol, also with Tijl De Bie, and a Postdoctoral Researcher at Aalto University with Prof. Aristides Gionis and Prof. Samuel Kaski. I defended my doctoral dissertation at Aalto University in December 2013, my advisor was Prof. Heikki Mannila. I graduated with distinction and I received an award from Aalto University School of Science for the best doctoral disseration of 2013. Before my doctoral studies, I have worked as a consultant in predictive analytics at Crystalloids, Amsterdam, and as a research intern at Philips Research, Eindhoven.
