Assistant Professor of English Language and Digital Humanities (tenure track), PhD

Tuomo holds a PhD in English philology (2014) from the University of Helsinki. His research focuses on the multimodality of human communication, that is, how natural language and various forms of visual communication interact and cooperate with each other in different communicative situations. In addition to authoring several journal articles and book chapters, he has published two monographs on multimodality, entitled The Structure of Multimodal Documents (Routledge, 2015) and Multimodality: Foundations, Research and Analysis (De Gruyter, 2017, with John A. Bateman and Janina Wildfeuer).

At the Digital Geography Lab, Tuomo develops approaches that draw on recent advances in natural language processing, computer vision and machine learning, whose application is informed by theories of multimodal communication. He is also pursuing research on the linguistic landscape of the Helsinki Metropolitan Area, that is, which languages are spoken and where, in order to better understand the distribution of languages in space and time, and the potential for language contact.

Before joining the Digital Geography Lab in 2017 on a personal grant from the Finnish Cultural Foundation, Tuomo worked as a postdoctoral researcher at the Centre for Applied Language Studies at the University of Jyväskylä. As of 2018, Tuomo is Assistant Professor of English Language and Digital Humanities at the Department of Languages.

Academy Research Fellow, PhD

Olle holds a joint PhD in human geography and regional planning (2013) from the University of Tartu and Ghent University. As a human geographer, his broad interdisciplinary research interests focus on human mobilities in spatial, temporal and social contexts. He is particularly interested in how big data such as mobile phone and social media data can be used to examine individual spatial mobilities and behaviour, understand social processes and phenomena, and how this can be implemented in planning and policy. In recent years, he has examined ways to use big data in studying cross-border interactions, transnationalism, segregation, socio-spatial inequality and urban accessibility. Olle is currently working on his new Academy Research Fellow project "Tracing Interactions and Mobilities Beyond State Borders: Towards New Transnational Spaces (BORDERSPACE)".
