My research interests are primarily within the area of machine learning, i.e., artificial systems that learn from experience. Research in this area may be found under several different headings, including data science, data mining, knowledge discovery, big data analytics, predictive modeling and intelligent data analysis. My research focus is on ensemble learning and interpretable models, including decision trees and rules.

I am editor of the journal Machine Learning and at the editorial boards of Data Mining and Knowledge Discovery, Journal of Machine Learning Research and Intelligent Data Analysis.

I am project leader of High-performance data mining for drug effect detection, a 19 MSEK project funded by the Swedish Foundation for Strategic Research during 2012-2016. See press release (in Swedish). I am also at the management board of the project Integrated Dynamic Prognostic Maintenance Support (IRIS), lead by Scania AB, and supported by 11.6 MSEK from Swedish Governmental Agency for Innovation Systems (VINNOVA) during 2012-2017.

I organized a national workshop on data science on Dec. 4 and 5, 2014 – see the program here as well as an interview on this event in ComputerSweden here (in Swedish). An earlier interview on the event can be found here (there is also a Swedish version here) as well as a previous interview on data science here (in Swedish here).
