The Conversation Weekly is our network-wide podcast that brings in academics from across the globe to discuss new research and provide context for news headlines. I’m acting as co-host, covering for Gemma Ware while she’s on leave for part of this year. I’ve been with The Conversation as an editor in Toronto, Canada since 2018, and in taking on this new role, I’m excited about continuing to work with researchers — this time in audio.

This week, I spoke with economist Miguel Niño-Zarazúa at the School of Oriental and African Studies in London, sociologist Erdem Yörük at Koç University in Istanbul, and political economist Christine Corlet Walker at the University of Surrey, England. They’re all studying various aspects of welfare systems in different parts of the world, and they described to me how different factors — including political unrest, the COVID-19 pandemic, a global recession and political conflict — were affecting the provision of welfare services in both the developed and developing world.

I’m looking forward to working on future episodes of The Conversation Weekly and learning more about academic research around the world. I hope you enjoy the shows.
