Dr. Jacob Rieker was awarded a University of Jyväskylä (JYU) 2026 Visiting Fellow Programme Grant. Hosted by Dr. Dmitri Leontjev (JYU, Centre for Applied Language Studies), Dr. Rieker will engage in research collaborations on the DD-LANG (Dynamic Diagnostic Language Assessment) project, which is funded by the Finnish government. As part of the one-month visiting fellowship, he will offer professional development workshops to Finnish in-service teachers as well as seminars on Vygotskian approaches to qualitative research methodology and EPPIC’s EMI initiatives to researchers and graduate students in the Centre for Applied Language Studies. This fellowship represents a valuable opportunity to further strengthen the international collaborative ties between JYU and PSU Applied Linguistics, EPPIC, and the CLA.
