Dr Brent Mittelstadt

Research Fellow & British Academy Postdoctoral Fellow

Brent Mittelstadt is a British Academy Research Fellow in data ethics at the Oxford Internet Institute, a Turing Fellow and member of the Data Ethics Group at the Alan Turing Institute, and a member of the UK National Statistician’s Data Ethics Advisory Committee. He is an ethicist focusing on auditing, interpretability, and ethical governance of complex algorithmic systems.

His research concerns primarily digital ethics in relation to algorithms, machine learning, artificial intelligence,

predictive analytics, Big Data, and medical expert systems. Currently, he is examining the feasibility of ethical auditing of decision-making algorithms, and the development of standards and methods to ensure fairness, accountability, transparency, interpretability and group privacy in ‘black box’ algorithmic systems. His work has also recently crossed into the field of data protection and privacy law, in particular concerning the implications of the EU General Data Protection Regulation on the governance of AI and automated decision-making systems.

Previously, he has been part of the EPSRC’s PETRAS IoT Hub, to develop ethical guidelines for designing the health-related Internet of Things, and collaborated with Prof. Luciano Floridi on the ‘Ethics of Biomedical Big Data’ project at the University of Oxford. His doctoral research examined the ethical implications of personal health monitoring devices, in particular how these devices introduce medical concerns into private spaces and undermine ‘internal goods’ of traditional medical relationships.
