Rochester, Minnesota Clinical Profile


In the field of hematology, my particular foci are ITP, non-malignant hematology, myeloproliferative disorders, myelodysplastic disorders, coagulation disorders and palliative care.

In the field of medical ethics, I am actively involved in scholarship and research in the areas of end-of-life ethics, reproductive medicine ethics, genetic ethics, the ethics of biotechnology (including stem cell and cloning research), transplantation ethics, the ethics of new technologies (particularly cybernetics, nanotechnology and artificial intelligence), the philosophy of technology and science, and research involving teaching methods in ethics.

I have expressed these interests internally to Mayo by founding the Mayo Clinical Ethics Council, the Ethics Counsultatoin Service, the Ethics Education Committee, the Reproductive Medicine Advisory Board, the DNA Research Sub-committee of the IRB, the Institutional Ethics & Bioterrorism Task Force, and assisting the formation of the Transplantation Ethics Advisory Board and the Psychogenomic Ethics Advisory Board.

Externally, I am actively involved in several projects as Senior Fellow of the Center for Bioethics and Human Dignity in Bannockburn, Illinois, as a Fellow of the Council for Biotechnology Policy and the Wilberforce Forum, both in Washington, D.C., as a Fellow of the Institute for Biotechnology & the Human Future of the Illinois Institute of Technology/Kent Law School in Chicago, IL, and as a member of the HHS Secretary's Advisory Committee on Genetics, Health and Society in Washington, D.D.
