Ida Toth is a historian of late antique and medieval literary (and textual) culture working in the Greek, Latin, and Slavonic linguistic areas. She convenes graduate courses in Medieval Latin, Byzantine Greek, and Byzantine Epigraphy, and she supervises master and doctoral students in Late Antique and Byzantine Studies. Dr Toth's external appointments include charing the the International Commission for Byzantine Epigraphy and the Membership Board of the British Committee for Byzantine Studies. She is a co-editor of the series Studies in Byzantine Epigraphy (Brepols). Dr Toth has been awarded an Einstein Berlin-Oxford Visiting Fellowship for the project ‘The Seven Sages of Rome Revisited: Striving for an Alternative Literary History’ (2024-27).

Frédérique Duyrat studied at Sorbonne University in Paris for her undergraduate and graduate degrees. She graduated with an MA in 1996, then spent two years at the French Archaeological Institute in Damascus where she wrote a PhD on Aradus, the most northern Phoenician city, during the Hellenistic period. She took her PhD in 2000 at Sorbonne University, and then was awarded a Habilitation à diriger des recherches by the same university in 2010 for her work Wealth and Warfare. The Archaeology of Money in Ancient Syria. She taught Ancient History at Sorbonne University, then at the University of Orléans where she was also a member of the Institut de recherche sur les archéomatériaux – Centre Ernest-Babelon (CNRS), a laboratory specialized in elemental analyses of the metal of coins (2002-2013). In 2010, she was appointed curator of Greek coins in the department of Coins, Medals, and Antiques of the Bibliothèque nationale de France, before taking the position of director of this department in September 2013. She was appointed to her current post at the University of Oxford in September 2023. At the same time, she is the Director of Studies in the Monetary History of the Greek World (7th-1st century BC) at the Ecole Pratique des Hautes Etudes in Paris.

Tumour hypoxia (conditions of low oxygen) is known to be a major mechanism of resistance to radiotherapy. My research is focused on the biological response to hypoxia and specifically the level of hypoxia where radiation resistance is observed. We carry out mechanism focused studies on the signalling which occurs in these conditions, including the DNA Damage Response, unfolded protein response and changes to chromatin marks, with a view to identifying novel targets to target in combination with radiotherapy. As part of this approach we have repurposed drugs, known to be effective in hypoxic conditions, as hypoxia activated prodrugs therefore limiting normal tissue toxicity. We have been focused on both hypoxia and redox and are involved in a large collaborative effort to generate and validate novel redox probes for use in complex biological systems.
