 Brief biography

  Martin Mose Bentzen is an associate professor at the Technical University of Denmark where he teaches philosophy of science and ethics in engineering.
  He has a background in philosophy and wrote his PhD dissertation about deontic logic.
  Bentzen currently researches philosophical aspects of social robotics, in particular the possibility of devising logical systems for ethical robots, see
  If you are interested in more details, here is a CV.

  Current research

  Social robots will need to behave in accordance with human values and norms, and in some cases they will have to function ethically. Therefore, there is currently a possibility for ethicists and roboticists
  to collaborate on the project of devising a robot ethics.
  My contribution to this project consists in making logical systems for ethical and deontic reasoning.   These formal systems will help clarify the foundations of robot ethics and can be implemented in robots.
  In my MA thesis (2004), I examined the history of deontic logic and the logic of imperatives and in my PhD thesis (2010) I concentrated on multi-agent deontic systems.
  Recently, I have suggested a deontic logic which is more aligned with actual human reasoning than many other deontic logics, I have examined the limits of logic-based inherent safety of social robots,
  and I have formalized the ethical principle of double effect and applied it to ethical dilemmas of rescue robots, see
  My main research into machine ethics/robot ethics (with my collaborator Felix Lindner) is being documented on the web page of "The HERA project" (HERA: Hybrid Ethical Reasoning Agent)
  I also do some research in other areas , e.g. scientific modeling, causality, and philosophical aspects of biological robots.
  I am interested in communicating research outside of the scientific community. Therefore I contribute to newspapers and magazines, see here,
  and occasionally appear in the media, see here.
