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 2016-2021, Hjortland is the Principal Investigator of a project on the philosophy of logic, funded by the Norwegian Research Council. He is an external member of the Munich Center for Mathematical Philosophy (LMU Munich), and an area editor of logic for the journal Ergo.

Hjortland leads the research group Bergen Logic Group at the Department of Philosophy.
