The welfare of laboratory animals heavily relies on properly assessing their pain. Our ethical responsibility is to ensure that they are living in good standards, which not only benefits their well-being but also leads to more reliable research outcomes. However, recognizing and treating pain in animals can be quite challenging. We need to understand how animals process and express pain to address this issue. 

Currently, I am investigating pain expressions in Japanese macaques and marmosets, which are still commonly used as animal models in laboratories worldwide.
