On 10 October 2022, the Centre for the Study of Global Development (CSGD) held its first cross-hub seminar event to mark World Mental Health Day, where three guest speakers shared their research that aims to support the mental wellbeing of distinct groups across the life course. The presenters spoke to the CSGD’s core belief of the importance of tackling societal challenges through an interdisciplinary lens, and that by working across disciplines we can enhance understanding and create more inclusive and robust solutions.
