Her book Army and Society in Ptolemaic Egypt (Cambridge University Press, 2014) combines documentary evidence (papyri, inscriptions) with social theory to examine how the changing structures of the army led to the development of an ethnically more integrated society. She has also written several articles on Ptolemaic history and (forthcoming) articles on the role of ethnicity in the institutions of the new Hellenistic states and on legal and fiscal categories used by the Ptolemies and the Romans in Egypt. She is now preparing a new book called The Ptolemaic Empire for Oxford University Press and co-writing with the numismatist Cathy Lorber an article on wages and monetization in Hellenistic Egypt.
