I am a postdoctoral researcher at Department of Mathematics and Statistics, University of Helsinki, Finland.
My research interests include: theory and applications of logics of dependence and independence, intuitionistic logic, constructive logics, etc.



NEWS: I have recently received a research grant from the University of Helsinki for a project on "Logical analysis of nogo theorems in social choice and quantum foundations" (click for more information on the project). There is an open PhD student position within this project, click here for the job announcement.
