Justine Karst

Find our Sentientist Conversation on the Sentientism YouTube here and the Sentientism Podcast here.

Justine is Associate Professor at the University of Alberta in Canada. As an ecologist she studies the mycorrhizal ecology of forests. She is an Associate Editor for the Journal of Ecology and President of the International Mycorrhiza Society.

Justine has a naturalistic worldview, saying in our conversation “I’m not religious, I don’t believe there’s a god, but I am totally open to being wrong about that.” She tends towards an ecocentric moral scope but recognises the particular moral salience of sentience. She is working on putting that into practice.
