(Dr. phil., Göttingen University). Professor, University of Hamburg. In recent years her main focus has been on ethics and methodology in Plato’s later works and on ethics and politics in Aristotle. Currently she is working on a translation and commentary of Aristotle’s Nicomachean Ethics for the Berlin Academy Series. A serious side-interest of hers lies in phenomenology, especially the phenomenology of Martin Heidegger. She was in residence at Berkeley for the academic year 2006-2007, and is teaching one course each semester in 2007-2008; she will return in 2008-2009.
