Entrepreneur Cathy Tie aims to genetically modify embryos for disease prevention
According to a single-source report from The Guardian, Canadian entrepreneur Cathy Tie, who calls herself “Biotech Barbie,” has launched three biotech companies since early 2025 and is pursuing germline gene editing to prevent heritable diseases such as cystic fibrosis, Huntington’s, and hereditary cancers. Tie, who married and separated from biophysicist He Jiankui — the scientist who created the world’s first gene-edited babies and served three years in prison — says she wants to conduct her work openly and transparently with regulatory approval and venture capital funding. She argues that gene editing is “the most consequential technology of our generation” and that private funding is necessary because no public funding is available for such research. Tie has named her first human gene-editing company the Manhattan Project, drawing a parallel between understanding the atomic nucleus and the cell nucleus. The article notes that germline gene editing for reproductive purposes is banned in the UK, US, and China, and that international agreement prohibits research on embryos that could be brought to term. Tie’s birthday party at Carnegie Hall in late April featured a piano performance, and she has lived in Los Angeles, Toronto, and New York since early 2025, while discovering she was banned from China, her country of birth.
