Stephen Wilkinson's most recent research is on reproductive ethics and the regulation of reproductive technologies, especially the ethics of selective reproduction (practices that involve choosing between different possible future people). A book on this topic (Choosing Tomorrow's Children, Oxford University Press) was published in 2010.
A previous phase of work focussed on the commercial exploitation of the human body and culminated in his first book, Bodies for Sale (Routledge, 2003).
He has also written on various other ethics topics including: biomedical research, conjoined twins, futility, mental illness, passive euthanasia, and resource allocation.
He is the holder of a Wellcome Senior Investigator Award (jointly with Professor Rosamund Scott of King's College London) on reproductive donation (http://reproductivedonation.com/).
