I was co-curator of the HSBC Money Gallery at the British Museum and have curated and contributed to a number of temporary exhibitions, including Earlier Monetary Unions, From Alexander to Mark Antony: Images of Power on Ancient Coins and Brief Lives. The Changing Currencies of Western Europe (at the British Museum), History Re-stored: Ancient Greek Coins from the Zhuyuetang Collection (at the Hong Kong Museum of History), and the traveling exhibitions Cleopatra of Egypt: From History to Myth and Forgotten Empire: the World of Ancient Persia.
I have written and edited more than 120 books and articles, including three volumes in the Sylloge Nummorum Graecorum series and Coin Hoards IX and X. I am currently writing a book about the city of Alabanda in Caria.
I am also currently heavily involved in projects that apply Linked Open Data principles to publication of and research in the numismatic and epigraphic fields. I was co-founder and remain a member of the steering committee of the Nomisma project (http://nomisma.org/).
Subsequently, I have been PI of a series of projects that have utilized this approach:
Online Coins of the Roman Empire (OCRE): http://numismatics.org/ocre/)
The Oxford Paris Alexander project (OPAL): http://www.classics.ox.ac.uk/opal.html)
Ancient Coins as Related Cultural Hertitage (ARCH): https://www.greekcoinage.org/arch-project.html
CHANGE. The development of the monetary economy of ancient Anatolia, c. 630-30 BC.: https://www.csad.ox.ac.uk/change
I am also working with the Institut Européen d'Archéologie Sous-Marine and the Oxford Centre for Maritime Archaeology on the publication of material from the excavations at Herakleion, East Canopus and Alexandria in Egypt (http://www.arch.ox.ac.uk/ocma.html), and have collaborated with the joint ISAW/Pavia excavations at Kinik Höyük in Turkey (http://www.kinikhoyuk.org/).
