Currently I am a full-time researcher, because I retired in November 2012, which provided me with an excellent opportunity to focus on research. I am working under the status of Professor Emeritus at Aalto University School of Business. My main reserch focus areas are:

* Multiple Criteria Decision Making: Theory, Applications and Tools (Currently, I am especially interested in the behavioral and psychological aspects of decision making.)

* Data Envelopment Analysis, especially incorporating preference information and selecting relevant factors for the analysis.

* Election machines

* Semantic Text-Analysis
