According to Bill McKibben in 2004's Enough: Staying Human in an Engineered Age, Hayes is ”one of the leading crusaders against germline manipulation,” that is, the modification of inheritable human genetic traits. Hayes has briefed United Nations delegates on the need for a global ban on human cloning, and has testified in support of international oversight of human biotechnologies, and against the cloning of pets. He is quoted in a 2002 article in Newsweek International declaiming the "vacuum of leadership," regarding responsible oversight of human genetic technology, noting that "[t]hese technologies ... have developed so rapidly that there is not the type of structure to regulate them". He holds a PhD from Energy and Resources from the University of California at Berkeley.
