Saul Albert is a senior lecturer in Social Science (Social Psychology) in Communication and Media at Loughborough University. His research explores the technology of social interaction at two ends of the spectrum of formalization. At one end, his work on conversational AI asks which features and mechanisms of human social action can be represented and modeled computationally. At the other, he studies how people make aesthetic judgements and interact while dealing with underdetermined cultural objects and situations. This program spans multiple, often incompatible disciplines, so his work builds methodological interfaces between them.

Rebecca Barnes is an Associate Professor based in the Nuffield Department of Primary Care Health Sciences at the University of Oxford.

Leelo Keevallik is a professor at Linköping University, Sweden, and has worked on analyzing language and the body in different linguistic and cultural contexts. She has analyzed dance classes, pilates sessions, human-robot interaction, how people shovel dung together, and how temporary job commuters manage the linguistic demands of their work life in a different EU country. The topics include speech prosody to coordinate action, non-lexical vocalizations in between bodily concerns and social action, and the building of turns through both syntactic and embodied means. She has been responsible for tens of hours of fieldwork and done hundreds of hours of multimodal transcription/analysis that has led to the central theoretical question: where does language begin and end?

He has taught workshops on phonetics and CA at York, online and around Europe. 

Simona Pekarek Doehler is professor of Applied Linguistics at the University of Neuchâtel, Switzerland. In her research she seeks to understand how participants to talk-in-interaction use grammatical constructions combined with bodily conduct as resources to accomplish social actions and how, in turn, linguistic and communicative resources (e.g., second language interactional competence) emerge from the process of interaction in situ and over time. Her current research interests are reflected in the recent Special Issues that she co-edited: The grammar-body interface in social interaction (Frontiers in Psychology/Communication, 2021), Longitudinal studies in Conversation Analysis (ROLSI, 2021), Early responses: Projection and the temporal coordination of actions (Discourse Processes, 2021).
