Professor of archaeology
I was appointed to the established Chair of Archaeology late in 2014. The job has roots going back to 1662 when Olof Verelius was made 'Professor of the Fatherland's Antiquities', making it probably the oldest archaeological post of its kind in the world. There have been long gaps in its tenure since Verelius' time, but it has been continuously filled since 1914. A year after taking up post I was fortunate to be awarded a major 10-year grant and a new job title from the Distinguished Professorship (rådsprofessor) programme of the Swedish Research Council.
I also hold an Honorary Research Chair in Archaeology at the University of Aberdeen; an Adjunct Professorship of Archaeology at Simon Fraser University in Vancouver; a Visiting Professorship in Nordic Studies at the University of the Highlands and Islands (Orkney and Shetland); an Honorary Senior Research Fellowship at the University of the Witwatersrand in Johannesburg; and I am a member of the Laboratory for Past Disaster Studies at Aarhus University in Denmark.
Career in brief
I began my archaeological career in the early 1980s, excavating for the Museum of London and at numerous sites in Britain, Germany, Malta and the Caribbean. I completed my BA in Medieval Archaeology at University College London's Institute of Archaeology in 1988, and afterwards conducted postgraduate research at the University of York on the Anglo-Scandinavian tenements at Coppergate. In 1990 I visited Scandinavia for the first time, as a recipient of the generous scholarships set up for foreign researchers on the excavations at the island Viking town of Birka. The experience was so positive that I emigrated here in 1992, working in rescue archaeology first for the National Heritage Board (Riksantikvarieämbetet-UV Mitt) and subsequently for the Arkeologikonsult consultancy practice.
In 1997 I returned to academia and began my formal relationship with this department, writing my doctorate here at Uppsala. After finishing my PhD in 2002 I taught for several years at Uppsala, before moving to positions at the universities of Oslo and Stockholm; I also co-directed Harvard's summer school in Viking Studies for five years. In late 2007 an exciting opportunity arose back in the UK when the University of Aberdeen announced the creation of an entirely new Department of Archaeology, the first time this had happened at a major institution in several decades. I was appointed as the inaugural established Chair of Archaeology there, tasked with building the new unit and guiding its development as an internationally leading centre for the study of the Northern past.
Building on the achievements of the Aberdeen department, coming back to Uppsala in 2014 was an academic homecoming. I am honoured to have been entrusted with responsibility for the discipline here, and humbled by the long line of my predecessors that include some of Scandinavia's most celebrated archaeologists going back more than three centuries. Following our 2013 merger with the former University College on Gotland, where archaeology was a flagship subject, we now have nearly 70 teaching and research staff, postdocs and PhD fellows, and are thus one of the largest Departments of Archaeology, Classical Archaeology and Egyptology in northern Europe.
My research interests fall into two broad categories, embracing the early medieval North c. 400-1100 CE, especially the Viking Age, and the historical archaeology of the Asia-Pacific region from the 1700s to the present.
I developed a fascination for the culture of the Vikings and their world during my early teens. My undergraduate studies in London offered the first opportunity to engage seriously with Scandinavia and the Viking world, and set the pattern of my working life ever since. My specific, current interests include Scandinavian and Germanic pre-Christian religion, ritual, sorcery and magic; Viking-Age mentality and world-view, what could called be the ‘Northern mind’; Viking-Age gender, sexuality, and identity; Viking-Age mortuary behaviour and funerary drama; the Scandinavian experience in the Frankish Empire; the Vikings in the East, including contacts with Islam and the Silk Roads; and the socio-cultural impact of natural disasters and climate change. Over the last twenty-five years or so I have lectured and travelled widely in the Viking and circumpolar world, and directed research projects in France, Iceland, Russia and Sápmi, besides several here in Sweden.
Although my current Chair has a traditional focus on Scandinavian prehistory, in fact I believe we all are (or should be) global archaeologists. Over the past decade or so, I have also developed interests in early modern and historical archaeology, with a focus on Oceania, the China Seas, and the Indian Ocean. More specifically, my research in these areas encompasses archaeologies of the colonial encounter; the archaeology of slavery; early globalisation and the social biography of commodities; the archaeology of the Maritime Silk Road; and the multicultural archaeology of the Pacific War (1941-45). More generally, my research also addresses three overarching themes: the social archaeology of conflict; the comparative archaeology of piracy; and the archaeology of traditional belief systems. This work has been pursued in many contexts, including southern Africa, Singapore, Australia, New Zealand, Japan, the Pacific Northwest Coast of Canada, the Bahamas and the southern Californian desert.
Among my theoretical and methodological interests are cognitive approaches to material culture, post- and decolonial approaches to material culture studies, archaeological ethics, the integration of archaeology and textual scholarship, and archaeological biographies (artefactual, commodity, social and collateral).
Primary research activity: The Viking Phenomenon
In December 2015, the Swedish Research Council made an unprecedented investment in early medieval scholarship, funding a major programme of research at the University of Uppsala to establish a new centre of excellence for the study of the Viking Age. The award appoints me to a Distinguished Professorship in pure research for a period of ten years. In addition to the position, the award brings with it a supporting budget of fifty million kronor (approx. $6 million USD).
The Viking Age (c.750-1050 CE) has long been a touchstone of identity in the Nordic countries, not least in Sweden where the primary project focus lies. While the Vikings enjoy a popular recognition common to few other ancient cultures, their history has been reinvented, used and abused to suit the needs of successive generations, in a process that continues today. Much of the recent research into the Vikings and their time has focussed on the complex process of state formation and Christian conversion that eventually gave rise to the modern Scandinavian nations. Far less attention has been devoted to the very beginnings of this trajectory: who really were the Viking raiders in a specific sense, why did they do what they do, what kind of societies produced them, and why did they start to expand so violently into the world at precisely this time? The answers to these questions concern the very origins of the Viking phenomenon. They are of crucial interest for understanding what made Sweden what it is today, and the sometimes problematic ways in which this knowledge of the past is received in contemporary society.
Under my direction, the ten-year programme will explore these issues with a core research group based at Uppsala University (Dr John Ljungkvist) and the Swedish History Museum (Dr Charlotte Hedenstierna-Jonson), working in close collaboration with a team from Tallinn and Tartu universities in Estonia. During the lifetime of the project we will be joined by a number of postdoctoral researchers, together with a number of international scholars, each making targeted contributions to their areas of expertise.
The project is designed as an umbrella programme that shelters several sub-strands of research. The key focus of attention will be on the critical century from 750 to 850 CE and the decades either side, embracing the early Viking Age and its foundations.
At the heart of the project is one of Sweden's greatest archaeological treasures, the largest cemetery of ship burials ever found, the classic site of Valsgärde in Uppland. For more than 400 years, each generation interred its prominent people of both sexes here in magnificent boat graves and cremations, filled with objects and animals. Excavated from the 1920s to the 1950s, together with the nearby sites of Gamla Uppsala, Vendel and Ultuna they tell the story of Sweden and its growth from the heart of the Mälar Valley. However, the very richness and complexity of the Valsgärde graves has meant that they have never been fully researched and published. The definitive analysis of the cemetery and the society behind the burials is one of our main priorities. As a crucial counterpart to this work on an old find, is the exploration of a new one: the extraordinary and exactly contemporary remains of a central Swedish raiding party, buried in two ships on the Estonian seashore where they came to grief at the very start of the Viking Age. These excavations, undertaken at Salme on Saaremaa in 2008-12, mark arguably the most significant Viking discovery of the last hundred years, and their analysis and publication is also incorporated in this project. Combining Valsgärde and Salme, we have the unique opportunity to reveal the world of the first Vikings, at 'home' and 'away', in a project of a kind never before attempted.
Underpinning these early Scandinavian enterprises was what we have chosen to call 'Viking economics', in the exact sense of the term (as distinct from the more general economic systems of the Viking Age) - the complex networks that motivated the early raiders and sustained their continued existence. Among the key issues to be explored here are the complex and multicultural roots of Scandinavian identity; gender constructions, and the roles played by both women and men in Viking culture; the prominence of slavery in Viking life; the existence of unique pirate polities, living outside the communities of the Scandinavian homelands; and the importance of the Vikings' non-Christian beliefs in their encounters with a wider world. International, cross-cultural comparative studies will add a further dimension to these investigations (see Distant Vikings below).
The Vikings are still today the most visible signal of Scandinavian heritage, and this research programme will be deeply embedded with contemporary concerns, ensuring the exploration of this long-lasting legacy for the widest possible public. The project award has already received wide international coverage in print and online media. Outputs will include workshops (held so far in Visby 2017, Santiago de Compostela 2018, and Athens 2019, with the next planned for Singapore), conferences and lectures; numerous publications including synthetic works, the cemetery reports from Valsgärde and Salme, and peer-review journal papers on Open Access; public outreach initiatives and an extensive online presence.
Viking Dynasties: the royal families of Lejre and Uppsala between archaeology and text
This Danish-Swedish collaborative archaeological research project is generously funded by the KrogagerFonden in Hellerup, and shared between the National Museum of Denmark (Dr Tom Christensen) and Uppsala University (Dr John Ljungkvist and myself). On the Swedish side it is formulated as a complement to the Viking Phenomenon programme, and focuses on the early royal dynasties based around the central places of Lejre and Gamla Uppsala. The background and inspiration for the project can be found in the very successful long-term collaboration between the fund and the archaeological research programme at Lejre.
The present project expands the focus to the larger political environment of the time - the context within which Lejre came into being - and includes its closest equivalent contemporary in Sweden, the royal manor and monumental landscape of Gamla Uppsala. As a result, the project is a collaboration between the existing Lejre team and the Uppsala University researchers who have for many years been investigating the Gamla Uppsala site. We are exploring the interactions and conflicts between the dynasties of Lejre and Uppsala, the Skjöldungas and the Ynglingas, and the development of their growing kingdoms that would ultimately lay the foundations for the modern nations of Denmark and Sweden. This is set against the background of earlier research, and the problems of combining evidence from archaeology and textual sources; we are assisted in this by project colleagues Sandie Holst, Ole Kastholm, Niels Lund and Daniel Sävborg. With the objective of shaping a new understanding of this critical period of socio-political transformation in Scandinavian history, the project is planned to run until 2020 and will result in a major edited volume.
The academic literature on the Vikings is vast, and in recent decades our view of the period has been transformed by new scientific discoveries and innovations in the humanities. However, despite these solid foundations, Viking studies remains an essentially introspective endeavour, locked into its chronological strictures and spatially bounded by the extended Scandinavian world. Current work often plays into paradigms fixed nearly a century ago: thus, we still read of ‘eastern’ and ‘western’ Viking Ages that are largely relics of the Cold War. For decades now there have been few major shifts in the basic interpretive framework within which the Vikings are studied. Whereas global, cross-cultural, multi-period approaches have proved successful in the study of European prehistory, such comparative methods are rarely applied in early medieval research. This project is attempting to change this situation, by comparing Viking-Age Scandinavia with selected island cultures of Oceania, focusing on Hawaii, the Solomons, French Polynesia, Rapa Nui, and Aotearoa. Significantly, though unrecognised in Europe, Pacific scholars have long-since identified the Vikings as the closest global parallel to the Polynesian voyagers. Migrations, maritime diasporas, seaborne raiding, complex demographic dispersal and politicised ritual power have been studied there with great methodological and theoretical sophistication - all manifested in unusually well-preserved archaeological monuments and a wealth of detailed written sources. These 'distant Vikings' let us view their Scandinavian cousins afresh, generating potentially major new insights into this critical period of Northern history.
From a gradual start in 2013, together with Dr John Ljungkvist I have been exploring practical, material approaches to the comparative archaeology of the Vikings and the Oceanic peoples, including two reconnaissance surveys of monuments and landscapes on Hawai’i (2013, 2017) and through a range of consultation meetings across the Pacific; the project launched more formally in 2017 with publications that can be found in the list below. A workshop in French Polynesia is currently being planned, bringing together Scandinavian and Pacific researchers to set out a research programme of renewal in Viking studies, and considering the potential feedbacks in the maritime archaeologies of Oceania.
Paradigms of Piracy: Private Law and Social Order in the Premodern World
Piracy has long been explored as a way of life central to pre-modern societies, which has left deep social, political and economic legacies down to our own times. This project employs comparative models of pirate communities as a lens through which to view the early Viking Age and the beginnings of the Scandinavian expansion across the then-known world. These themes are explored against a broad geographical range extending from the Caribbean, Bahamas and the American seaboard in the west to the Indian Ocean, China Seas and Malaysia in the east. A particular goal is the identification of material signatures of pirate activity, especially on terrestrial (as opposed to the more common marine) sites. Is it possible to develop a predictive model of pirate archaeology?
Secondary Research Activity: Historical Archaeology Projects
War of the Worlds: the Present Past on the Island Battlefields of the Pacific, 1941-45
This project is co-directed with Dr Rick Knecht at the University of Aberdeen, with origins in our previous and ongoing fieldwork on the 1944 Battle of Peleliu in the Republic of Palau, Micronesia. The Second World War was arguably the most traumatic complex event in human history, with troubled legacies that in the Pacific include today's unresolved tensions between Japan, China, Korea and other former combatant nations. The island battlefields of the region formed a zone of cultural interaction and conflict for all the peoples of the Pacific and many from outside. Both directly and thematically, causal links can be traced back from the War to the colonial contact period, and literally underlying the wartime landscapes (but often overlooked) are the earlier settlements and sacred sites of the indigenous islanders. The properly contextualised study of the conflict therefore involves a chronological range and complexity that extends from the 1500s to today. The War of the Worlds project has a dual base in Uppsala and Aberdeen, with research extending to Palau, the Marianas, the Solomons, Vanuatu, Papua New Guinea, Hawaii and elsewhere in the Pacific. It includes a strong participatory involvement of researchers from the region, particularly with Pacific Islanders and traditional knowledge bearers. Themes of death and memory naturally take centre stage, and the project focuses on the preservation of the battlefields as places of reflection and commemoration. Archaeology has an innovative role here as a medium of reconciliation, linked to the realities of ethically-sound eco-tourism and its potential for lifting marginal economies. Three seasons of fieldwork have been conducted so far on Peleliu in 2010, 2014 and 2015 with funding from the US National Park Service (American Battlefield Protection Program), and in 2017 extensive contacts were established with archaeologists on Okinawa. We have held workshops in Kyoto and Naha, which mark the first-ever collaboration between Western, Japanese and Okinawan archaeologists studying the material legacies of the war. A volume of papers from these meetings will be published with Routledge in 2020, and other publications from the project can be found in the lists below.
Imperial Addictions: Material Histories of Opium from the Indian Ocean to the China Seas
The international opium trade of the eighteenth and nineteenth centuries transformed cultures and communities on a massive scale. Wars were fought to secure the trade, governments were toppled or subverted, and the mercantile aristocracies of Europe flourished on its profits. This same period saw the origins of globalisation in the modern sense of the term, a time in which a handful of crucial commodities radically changed the world. This project focuses on the concept of 'collateral archaeologies' - not the core of the trade itself, but the world that opium touched and changed, and the myriad human impacts that resulted. A series of multi-authored case studies are brought together, exploring shipwrecks, battlefields from the Opium Wars, camps of migrant Chinese workers in various countries, the supply bases along the routes, and also those displaced by the trade and their new lives to which opium had driven them. My own research focuses on the various East India Companies, especially that of Sweden, and their bases in the so-called Thirteen Hongs of Canton (modern Guangzhou), with further research in Mauritius and Australia. The project will be published as an edited volume in 2019This project is co-directed with Dr Rick Knecht at the University of Aberdeen, with origins in our previous and ongoing fieldwork on the 1944 Battle of Peleliu in the Republic of Palau, Micronesia.

The properly contextualised study of the conflict therefore involves a chronological range and complexity that extends from the 1500s to today. The War of the Worlds project has a dual base in Uppsala and Aberdeen, and will soon expand to Liverpool, with research planned in Palau, the Marianas, the Solomons, Vanuatu, Papua New Guinea, Hawaii and elsewhere in the Pacific. It includes a strong participatory involvement of researchers from the region, particularly with Pacific Islanders and traditional knowledge bearers. Themes of death and memory naturally take centre stage, and the project focuses on the preservation of the battlefields as places of reflection and commemoration.

I believe that as academics we all have clear obligations to share the results of our research through an active engagement as public intellectuals, and to thereby offer our work for more participatory debate. Over the years I've contributed regularly to radio and television programmes in several countries, either as a consultant on content or presenting my own research. I've made several live radio broadcasts, including BBC Radio's In Our Time and on public radio in South Africa. In 2014 I appeared in the live-broadcast film Vikings Live from the British Museum accompanying the exhibition there, which was transmitted in 400 UK cinemas and later worldwide. Recently I've worked as the Historical Consultant for Real Vikings, a documentary series from History Channel Canada to support their successful TV drama Vikings. This has involved filming in nine countries, often with cast members from the drama, exploring the Viking world behind the fictional entertainment.
Museums are a primary forum for the public dissemination of our research, and I have contributed to numerous exhibitions and their accompanying catalogues in Scandinavia, Europe, the US and South Africa, including the British Museum and several national museums. Most of this work has concerned the Viking Age, but other topics include Sámi religion, shamanism, and the cultural history of sexuality. I regularly give public lectures and publish in popular science magazines, and my online presence includes the YouTube recordings of the series of Messenger Lectures that I held at Cornell in the fall semester of 2012, on the theme of The Viking Mind.
My work as part of the team studying the burial of a female Viking warrior (grave Bj.581 on the island of Birka, Sweden) was very widely covered online, including reports in Science, and reportage in over 130 international news agencies. The paper is high in the top 5% of global research ever measured by Altmetric, and was the 43rd most accessed of 2.2 million papers published in the world during 2017. In addition, Science News named the find as one of the top 10 scientific discoveries of 2017.
The Viking Phenomenon project (see above) has received extensive print and online coverage, including several extended interviews and profiles. In Scandinavia this has included all the main national newspapers, radio and television broadcasters, and further afield the project has been reported in periodicals such as The Washington Post and a very wide range of web-based media, together with features on History Channel. Major international coverage includes an article in Science and a 30-page cover story for National Geographic magazine in March 2017. We continue to engage with NatGeo across their 'cross-platform brand universe' (combining print circulation, downloads and social media), where project-related pieces have reached 30.9 million readers.
