Having a particular interest in clinical ethics, I’ve been working on a study for a process of informed consent for cancer patients. Personalized exchanges between patients, with unique life stories, and medical caregivers, who made efforts to master appropriate treatment techniques, gave various insights on treatment techniques. I plan to continue further research in order to facilitate constructive discussion on iPS cell ethics.
