Ole Hjortland's research is on logic and rationality. What makes an argument a good argument? What does it mean to think and act rationally? Are there universal norms for good reasoning? In 2016-2020 Hjortland is the Principal Investigator of a project on the philosophy of logic, funded by the Norwegian Research Council. He is an Associate Fellow of Arché Research Centre, University of St Andrews, and the Munich Center for Mathematical Philosophy, LMU Munich.

Hjortland serves on the editorial board of the Norwegian Journal of Philosophy and Ergo: an open access journal of philosophy.
