    Dr. Fedyk conducts research at the intersection of ethics and philosophy of science. More specifically, he is interested in discovering methodologies that better harmonize ethics and science. For that reason, he has a deep commitment to advancing research in nursing science and health systems science, as both academic fields are areas where the ethical and scientific can be increasingly tightly entwined.
