Alexander is an independent historical and archaeological researcher of Viking Age and early medieval England.

He uses quantitative modelling, GIS mapping, and codicological analysis to explore how early medieval landscapes were shaped, organised, and understood.

His Routledge monograph, published on 22 June 2026, provides the first major reassessment of the Danelaw in more than three decades. Bringing together documentary, literary, scientific, and archaeological evidence, it applies innovative statistical modelling to reconstruct the regions of Viking Age England and reassess the Danelaw’s duration, boundary, trade dynamics, and identity. The findings reveal a far more intricate political geography than traditionally assumed, including counter‑intuitive evidence for increased trade during this period.

Alexander's research interests include:

• The Danelaw as a dynamic legal region and social construct.
• The spatial extent of Scandinavian influence in England.
• The transmission and reception of early English law codes.
• Modelling and mapping historical patterns across multiple datasets.

Alexander is a member of:

• The Offa's Dyke Collaboratory Research Network
• The Medieval Loyalty Research Network
• The Rochester Cathedral Research Guild
  Alexander has contributed contextual articles to Rochester Cathedral's Textus Roffensis translation and transcription project led by Dr Christopher Monk .

Agreed in the late 9th century AD between Kings Alfred and Guthrum, Alexander's doctoral research at the University of Bristol concerned the Danelaw Boundary (c. AD878 – 890) between the Danelaw and the Kingdom of Wessex. Alexander's supervisors were Professors:

• Stuart Prior
• Lucy Cramp
• Levi Roach (of the University of Exeter)
• Mark Horton
• Joanna Brück .

Research included:

• the analysis of diverse data sources and the identification of anomalous patterns
• the formulation of a methodology to examine a varied dataset, compiled from broad sources, using flat databases as well as landscape and data visualisation
• the development of solutions to resolve research problems by adapting multidisciplinary methods.

During and after his doctoral research, Alexander has been a chair, panellist, and speaker at various international medieval studies and medieval archaeology conferences, including at the Universities of Bristol, Bournemouth , Durham, Leeds , Lincoln, and Oxford. He has also given lectures to archives and to societies, such as the Medway Archives and Hertfordshire Anglo-Scandinavian Society respectively. Alexander has also co-organised several postgraduate archaeology and medieval conferences.

Alexander has led various seminars, tutorials and workshops, on archaeological practice and theory units, for first and second year anthropology and archaeology undergraduates including:

• Comparative World Archaeology
• Pre-Excavation Techniques (renamed Archaeological Practice )
• Social Theories
• Material Culture

Alexander has experience of marking first and second year undergraduate essays and exams. He also has experience of teaching adult learning classes which introduce Viking Age England.

Alexander has developed and built a variety of fluid websites for the media, education, and heritage sectors. He also has experience of building user platforms, possessing a working knowledge of the development and deployment of Progressive Web Apps (PWAs).

He is fully competent in Microsoft Office suite, Adobe Creative Cloud (including Adobe Illustrator, InDesign and Dreamweaver), Quantum GIS (QGIS), ReflexW, Geoplot, and TerraSurveyor. He also has a working knowledge of Python, HTML, CSS, PHP, JavaScript and SQL.
