Tarja Knuuttila is a Finnish philosopher of science known for her work on scientific modeling, representation, and the epistemology of scientific practice. She has developed an influential account of models as epistemic artifacts — concrete objects that generate knowledge through construction and manipulation rather than purely through representation. Her research spans philosophy of science, history of logic, and the philosophical analysis of analogical and inferential reasoning.

Contributed to the philosophy of scientific modeling and the epistemology of idealization

Produced interdisciplinary work bridging philosophy of science, history of logic, and computational modeling
