Wendy Lipworth is a medically-trained bioethicist and health social scientist at Sydney Health Ethics at the University of Sydney. Her program of research focuses on the ethics and politics of medical therapeutics, with an emphasis on how evidence of the safety, efficacy and cost-effectiveness of pharmaceuticals and other related technologies (e.g. medical devices and biological therapies) is generated, disseminated and used in determining access to interventions. She aims to contribute to policymaking by examining the public, professional and political debates about these processes. She uses a combination of theoretical and empirical research methods to characterise stakeholders‚Äô beliefs, values, interests and arguments for action; distinguish between those that are more or less morally justifiable; and devise ways of proceeding when equally valid positions compete or conflict.
