Tim holds responsibility for all day-to-day operational issues, and along with Julian Richards has a shared responsibility for strategic development. Tim also directly manages the HERALD project , and and teaches on the MSc in Archaeological Information Systems and other Postgraduate and Undergraduate courses.


By way of Exeter (BA) and Birmingham (MA), Tim originally started at the ADS in a short-term post designed to manage the integration of all ALSF archaeology projects , this developed into a varied role leading on larger database and web map-driven projects such as the Roman Rural Settlement of Britain []. His many and varied professional interests  include semantic interoperability, Linked Data, the PDF/A standard(!), and large-scale data analysis. Thanks to his participation in the ArchAIDE project, he's also developed an (unhealthy) interest in the practical and conceptual classifications of pottery types, particularly Amphorae.

Tim's PhD was based on examining the investigative and publication histories of archaeological excavation in England. As a consequence he's developed an interest in the historiographical and epistemological foundations of archaeological practice, and the potential of unpublished fieldwork reports (so-called 'grey literature') and digital archives in dissemination strategies.

Prior to joining the ADS Tim worked in commercial archaeology for 6 years, primarily at Birmingham Archaeology (formerly BUFAU), working on a range of urban and rural sites across the West Midlands and beyond. The highlight being the multidisciplinary study at Catholme, Staffordshire []. In his younger days he also had the fortune to work extensively overseas, including excavation and survey projects in Cyprus, Italy and Egypt.

When he's not  talking about himself in the third person or dealing with computers and archaeology, Tim drinks tea, enjoys watching and listening to cricket, follows the fortunes and (more often) misfortunes of Everton Football Club, and tries to complete cryptic crosswords. He's currently wondering about what really happened to the Arteta money.



PhD thesis: Holes in the Archaeological Record: investigating 'unpublished' sites from modern excavations in England and the potential for the advancement and loss of archaeological knowledge


Supervisor: Prof. Julian Richards

The broad research aim of this thesis is to study the phenomenon of the 'unpublished excavation' in post-war England and assess its potential impact on how archaeology is practiced in the country, from planning and guidance to research and teaching.
This broad objective includes a number of subsidiary aims, the most important of which is to provide a historical and theoretical background to the study in order to establish what is meant by 'unpublished'. It will aim, by an analysis and discussion of the available literature, to identify several key themes in modern/post-war archaeological practice and publication in England.


The thesis also aims to establish whether unpublished – and indeed published – sites can be quantified at a local or national level. It will achieve this by attempting to draw up a definitive gazetteer of all archaeological interventions undertaken in three counties (Staffordshire, South Yorkshire and Surrey), and identifying the literary output of each. By classifying these types of output at a detailed level (specifically the different types of 'grey literature') it will also study and identify cultural trends in publication. These trends may, it is hoped, provide further information regarding temporal or geographical bias for unpublished sites; for example is non-publication a problem confined to urban areas with complex stratigraphy? This will also be extended to look at the economic and social background to excavations; the comparative levels of publication from urban re-development and industry prompted excavation. Furthermore, the thesis will also aim to identify potential historical or methodological bias within the datasets studied, for example is there a difference in output between large open area excavations with high post-excavation costs as opposed to small targeted interventions?

Inherent in all this will be the continuing theme of research value: are sites published because they are typical of their type, or tell us more about a specific period or place? By the same logic, are sites not published because they are relatively unimportant? The thesis will also aim to look at the differences in publication outputs in the archaeological 'information flow', and if this has had an adverse effect on planning mitigation or research. Associated with this is the idea of archaeological 'black-holes'; is it possible that data has been lost, or is in the process of being lost, and what does this mean for archaeology as an academic discipline and as an important part of the planning process?
