Aaron Traywick (December 19, 1989 – April 29, 2018) was an American life extension activist in the transhumanism and biohacking communities and former founding CEO of Ascendance Biomedical. He sought to develop gene therapies to make inexpensive treatments available for incurable conditions such as AIDS and the herpes simplex virus. His lack of any medical training and his unconventional methods—such as broadcasting an associate injecting himself with an “untested experimental gene therapy”, then later doing the same to himself in an onstage public demonstration—drew widespread criticism.
