Academic research in Lab Animal Centre2R-research = Reduction and Refinement -alternatives
3R's principle (Replacement, Reduction, Refinement =korvaaminen, vähentäminen ja hyvinvonnin edistäminen) is the leading practice in laboratory animal use. 2R -researchs and other practices focus on increasing the welfare of lab animals by improving their housing environment and experimental procedures. The research in LAC is lead by professor Timo Nevalainen.

Cost-benefit analysis of animal experiments
In order to justify the harm caused by experiments to animals, the benefit from the experiment must be higher than the harm caused to animals. To evaluate the necessity of animal experiment, Cost-benefit analysis has been developed.
