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.

Medieval towers are a ubiquitous feature of the landscape in Greece – over 300 have been recorded. Little, however, is known about them. Many theories abound, but no in-depth research has been undertaken into their function, when they were built and by whom. My research aims to shed light on this by utilizing GIS, historical documents and contemporary maps, coupled with an extensive landscape survey of the surviving monuments, to recreate the medieval topography on the island of Euboea where 80 have been identified.

A by-product of my research has been the identification of many hitherto unrecognized maps of the island, 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.
