• The main focus of my research over the past five years has been the mining of telecommunications and transportation data sets to provide insight into human socio-economic behaviour at the regional and national scales. The breadth and depth of these data sets has enabled me to pursue a wide range of interests including: firm internationalisation and location choice, social network analysis, disruption effects in public transit and airline systems, and constraints on access to opportunity in London.
• Looking forward, I hope to begin bringing in some historical perspective: working to produce a book that looks back at nearly 120 years of location theory; exploring the historical growth of Britain's telecommunications system; and examining the connection between telecommunications/ICT usage and London's innovative small firms. The other area of interest is in quantification: improving our understanding and prediction of how disruptions produced by weather, crowding, or security issues produce knock-on effects on nearby stations through the integration of usage data and better modelling of route choice by transit users; and looking for ways to measure the relationships embodied in the social networks of businesses.

• My research drew on ‘quantitative social science’ methods – the augmentation of traditional social science with large behavioural data sets – to engage with economic development, accessibility,
• and inclusion issues in new ways at multiple scales. To accomplish this, I have developed and co- developed efficient methods and algorithms for storing and analysing massive data sets of between one and ten billion records each. Drawing on an extensive and intensive review of planning
• and location theory, I have connected these analyses to emerging trends in digital and physical interaction, and to contemporary challenges in balanced urban and regional development.

• Building on practical experience gained principally at Cyber Dialogue, I've continued to develop code libraries that support long-term maintainability of sites by non-technical clients. The measure off success for me is how topical the content on a web site remains six to eight months after launch.
• Recently, I've focused on WordPress as a CMS (Content Management System) for web sites -- users get version control and an easy interface, and I can pluck the content out of the database and present it on a standard-issue web site.
