Martin Callanan is an associate professor and program director for archaeology at the Department of Historical and Classical Studies. He works on alpine snow patches and frozen cultural heritage in central Norway. In the research project with the Norwegian title Utvikling av lokale jaktteknologier i sen jernalder og middelalderen (c. 700-1400 e.Kr), he investigates changes in bow and later crossbow technologies in the period between the 8th and the 15th century, based on data from snow patches. Furthermore, the project analyses these changes against the background of overreaching political, military, and social processes and developments, and in the prolonging of this, broader questions such as economy and in particular the utilization of outfield resources in the iron age and the Middle Ages. In his project with the Norwegian title Sørsamisk arkeologi i jernalderen og middelalderen, the key objective is to investigate and develop an analytic and systematic overview over South Sami findings and localities in the region.

Roman Hankeln, professor of music history, is teaching at NTNU’s Institute of Music and the Institute of History and Classical Studies. Hankeln’s research focuses on medieval liturgical vocal music («Gregorian chant», «post-Gregorian chant»), its style and cultural-political context. Many of Hankeln's writings are centred on the medieval cult of saints in a pan-European perspective. Emphasis lies on the reflection of political ideology in chants for sainted rulers like St. Olaf, St. Knud, Charlemagne, empereror Henry II as well as soldier saints like St. Maurice and the Theban legion. Especially important in Hankeln’s work are editions of saints’ offices in the series HISTORIAE which are published by him, leading a team of experts on behalf of the International Musicological Society. Another branch of Hankeln’s activity addresses Gregorian chant at the transition to the early modern age. Here, Hankeln has published on late Latin chants (Cantiones), the musical practice in northern German nunneries, and the transition from catholic to protestant liturgy in Norway during the reformation era (Missale Nidrosiense and Breviarium Nidrosiense). Recently he is involved in the online cataloguing of medieval fragments at the Gunnerus-library in Trondheim.

Rakel Igland Diesen is a former PhD student at the Department of Historical and Classical Studies (IHK), NTNU. She is a medieval historian with a particular interest in childhood history and Nordic medieval hagiography. Her dissertation from 2023, Looking for Children in Hagiography: Conceptions and representations of children in Nordic miracles and vitae from the 12th to the 15th century, is positioned within childhood history, intersecting with the fields of social history, cultural history, and the history of ideas. Its focus is on the medieval children who are found in a collection of texts about the native saints and their workings. The study’s combination of sources, historical period, and regional focus contributes to filling in a research gap in childhood history. 

Martin Veier-Olsen is a PhD candidate in history didactics at the Department of Teacher Education. He has a master’s degree from the Teacher Education Programme in history at NTNU.

Lasse Hodne is professor of art history at The Department of Art and Media Studies. He has particularly worked with Italian visual art from the Middle Ages and the Renaissance, and from 2002 to 2006 was deputy director at the Norwegian Institute in Rome. His research has dealt with the relationship between art, philosophy, and theology, as well as issues related to iconography. Two of his books - Sponsus amat sponsam and The Virginity of the Virgin - are devoted to Marian iconography. In addition, he has studied the relationship between portrait art and facial perception, based on psychological and neuroscientific methods. The research on Renaissance portraits has partly been carried out within the framework of PoeticA – an international, EEA-supported project in neuroaesthetics. A third field of interest is the reception of art, particularly the interest in the Middle Ages in modern times and the flourishing of interest in ancient classical art in the Renaissance and Neoclassicism. The latter has been the starting point for (so far) six articles on the German art theorist Johann Joachim Winckelmann (1717-1768).

Based on this, she has contributed to national and international workshops, and co-edited the anthology Complexity and Dynamics - Settlement and landscape from the Bronze Age to the Renaissance in the Nordic Countries (1700 BC - AD 1600) which came out in 2023.

He is also involved in a project on drama and aesthetic learning processes in history education. 

Ulrika Mårtensson is professor of Religious studies at the Department of Philosophy and Religious studies. Her research focuses on the early and medieval Islamic scientific disciplines, and their significance in contemporary contexts (including in Norway). The two specific areas she is concentrating on now and for the future are: (1) Islam’s sacred scripture The Qur’an, written in Arabic language. Focus is on possible relationships between the scripture’s 600’s context, with consideration also of the Arabs’ ancient history, and its theory contents, especially theories of natural law, social contract, language, and rhetoric. The main question is to what extent theories may reflect changes in agriculture and legal rights for farmworkers and peasants (of both genders). (2) The famous jurist, Qur’an commentator, and historian al-Tabari (d. 923) and the school of law he developed during his career in Baghdad. Focus is again on relations between societal context and theories, particularly al-Tabari’s human rights-thinking and peasants’ rights. In addition, al-Tabari’s jurisprudence, Qur’an commentary, and history provide important theories and analysis for the research on the Qur’an itself.
