Since 2011, Taddeo has collaborated with the NATO Cooperative Cyber Defence Centre of Excellence (CCD COE) to develop a research network devoted to the analysis of the ethical and policy gap surrounding cyber-warfare. In collaboration with CCD COE, she has organised two workshops on this topic, the most recent of which was held at Magdalen College, Oxford in November 2014.

From 2010 to 2012 she held a Marie Curie Fellowship at the University of Hertfordshire, where she was working on information warfare and its ethical implications.

She holds a PhD (Doctor Europeus) in philosophy from the University of Padua. Her PhD thesis focused on the epistemic and ethical implications of the occurrences of trust in distributed artificial systems.
