Margaret is Professor of Bioethics at University of Notre Dame Australia. She was previously Samuel Gale Professor of Law at McGill University. As an ethicist, Professor Somerville deals with issues like euthanasia; the treatment of seriously disabled new-born babies; withdrawal of life-support treatment; abortion; prenatal genetic screening; new reproductive technologies; \"designer babies\"; human embryo stem cell research; cloning; \"manimals\" – embryos with both human and animal genes; artificial sperm and ova -- making embryos from two same-sex adults; synthetic biology; transplant tourism; xeno-transplantation – the use of animal organs in humans; capital punishment; the law and ethics governing armed conflict; the ethics of robotic warfare; same-sex marriage; polygamy; and so on. A returning guest, Margaret joins us as we explore the convoluted area where faith meets ethics, medicine, science, sociology and the law.
