On November 28-December 7, 2016, Tatyana Yakhontova visited Birkbeck, University of London, with a short-tem scientific mission (STSM). Her host was Dr. Bojana Petric, Department of Applied Linguistics and Communication Studies, a team leader of the Working Group 2 within the COST Action IS1401ELN. The overall purposes of the STSM included: intensive consultations with Bojana Petric on interviewing in writing research and on developing English writing courses for mature learners; visits to the workshops and seminars, relevant to the purpose of the mission; library work; a presentation on writing issues at the seminar of the Department of Applied Linguistics and Communication Studies. These aims were fully accomplished during the STSM, which appeared to be a great opportunity of strengthening collaboration in COST Working Group 2 and furthering the implementation of its research goals.
