Initially as finance manager and subsequently as general manager I have worked in various manufacturing and distribution companies throughout the world. For the last 18 years I have worked as a business consultant and been running my own company.

A number of years ago I began research with a view to writing a history of the Greek island of Euboea, where I live. Whilst its pre-historic and classical history have been well-documented and covered by historians ancient and modern, most records of the late medieval period, when it was controlled by Latin and Venetian overlords, perished with its annexation by the Ottomans at the end of the 15th century. This left a fascinating gap, which I believed could to some extent be filled by an understanding of the hundreds of monuments that survive from the period.

There followed two years of general research, mainly at the British School at Athens, and evening classes in medieval Latin  palaeography at the Centre for Byzantine Research, also in Athens, prior to preparing a research proposal and enrolling at  the University Birmingham.

Since Johannes Koder’s ground-breaking study in 1973 little work has been undertaken to further understand the topography of the Greek island of Euboea during the period from 1205 when Frankish forces took control of the island of Euboea (then called Negroponte) and its annexation by the Ottomans in 1470. Yet significant progress has been made in the interim in identifying and studying individual monuments of the period, and many contemporary maps of the island, previously in private hands, are now in the public domain. My thesis is focused on exploiting these sources to prepare a composite map of the era with a view to shedding light on economic and political developments during the period.

A by-product of my research has been the identification of many hitherto unrecognized maps, and an understanding of the methods of preparation and accuracy of the contemporary cartographic sources. This, in its turn, has provided the base for a comparative study (ongoing) of the cartographic sources of the period in order to achieve a better understanding of the development of cartography in the Eastern Mediterranean in the late Medieval and early Renaissance period.
