Through her work, Lie examines how to create in our current geological era proposed as the Anthropocene, with its accompanying philosophical and ethical questions, as well as for possible futures. She points out blind zones in social and built structures and proposes new alternatives for coexistence to the human-exceptional/centric. Lie works with sound, performance, installation, and text; alone and in collaboration with others in creative fields and fields of scientific research, with knowledge producers such as educational institutions and libraries, and local communities.
