He also has formal training in bioethics and frequently performs empirical work to answer challenging ethical questions. Dr. Cowan has investigated capacity to consent to research and informed consent for HIV testing. He has also been actively engaged in conceptual work in ethics, having published ethical analyses of unconsented HIV testing in cases of occupational exposure, allocation of HIV drugs for prevention versus treatment and the ethics of pre-exposure prophylaxis in HIV prevention trials. Dr. Cowan is very familiar with the ethical issues pertaining to research including issues surrounding informed consent, biobanks and bio-specimens, confidentiality, risk-benefit analysis, equipoise, global health research and due and undue inducement.
