Heidi Wunderli-Allenspach (born 1 January 1947) is a Swiss biologist and was the first female director of ETH Zürich.

Education issues were always at her heart; during that time the curriculum was redesigned and the Bachelor/Master system was introduced.

As a representative of ETH she was a member of the foundation for student housing, for childcare, and of various institutions for the promotion of natural sciences in education, among them the Swiss Science Center Technorama in Winterthur and the NaTech educational program.

[2][3] Wunderli-Allenspach's research was focused on physicochemical and cell biological aspects of drug absorption, distribution and elimination in the body.

Her work was relevant in vitro models for the blood-brain-barrier as well as for epithelial barriers that were established in order to study the transport of drugs through and the interaction of drugs and excipients with membranes and cells under standardized conditions.
