Goldberg and McGee BMC Public Health 2011, 11:770 http://www.biomedcentral.com/1471-2458/11/770 earned a distinction, and which currently serves as the basis for a book proposal under review at a university press. DSG’s general approach to the undertreatment of pain, regarding the error of reducing it to a question of opioid policy, has resulted in a number of publications, commentaries, and presentations in peer-reviewed journals and conferences, as well as invitations to speak at a variety of local, national, and international venues. DSG has also produced multiple publications on global health and public health ethics, and has papers on both subjects forthcoming in major scholarly journals and in an anthology on global health to be published by Oxford University Press. DSG was recently named a 2012 Visiting Fellow with the Birkbeck Pain Project at Birkbeck, University of London. SJM has published over a dozen papers in the area of public health and ethics. The topic of ethics and pain is the focus of the Center for Practical Bioethics’ PAINS Project, for which SJM is a consultant. SJM has multiple forthcoming publications in the area of pain, public health, and ethics and is currently developing a book on the ethics of prevention. As the first public health ethicist at the University of Kansas Medical Center, SJM is developing new courses and research programs in public health, pain, and cancer. Competing interests Neither DSG nor SJM has any competing interests to declare. Received: 20 June 2011 Accepted: 6 October 2011 Published: 6 October 2011 References 1.
