Alan is also engaged in a broad range of research projects and programs, including the Berman Institute’s science programs: the Stem Cell Policy and Ethics (SCOPE) Program; the Program in Ethics and Brain Sciences (PEBS-Neuroethics); and the Hinxton Group, an international consortium on stem cells, ethics and law; and the eSchool+ Initiative. Recent research has focused on using deliberative democracy tools to engage with communities about their values for allocating scarce medical resources like ventilators in disasters like pandemics. Additional recent work has focused on ethical challenges related to gene editing, stem cell research, social media, public engagement, vaccines, and neuroethics. (Publications)
