Dayalan joined the Evangelical Alliance's South Asian Forum team in 2018 to help oversee events and new resources. Having taken over from Manoj Raithatha as the forum's national coordinator, Dayalan now organises cross-cultural mission training events to help churches reach out to those of other faiths. As part of his role, he also facilitates relationship building and joint mission among South Asian churches, and helps them integrate into the wider UK church.
