Why Storytelling Matters: Climate, Community, and Hope with Roberta Bosu

In this episode of Global Health Talks, we are joined by Roberta Bosu, a strategist, campaigner, and storyteller working at the intersection of climate, nature, and human rights.   Roberta takes us back to her childhood in the mountains of Sardinia and shares how her connection to nature shaped the work she does today. We talk about career paths that don't follow a straight line, the courage it takes to redefine success on your own terms, and how she moved from diplomacy and corporate sustainability to leading campaigns that advocate for the rights of nature and Antarctica. Together, we explore the power of storytelling in climate action, why creativity and art are not optional but essential for addressing global challenges, and the power it has to make us imagine a different, better world. Roberta also reflects on what it means to communicate with authenticity, connect with communities, and remain hopeful in a world facing environmental and social crises.

Women’s Health, Breaking Stigmas, and Changing Policies with Dr. Petra Salarić

In this episode of Global Health Talks, we are joined by Dr. Petra Salarić to explore why breaking stigma and taboo topics is essential for improving public and global health. Petra shares her journey as a researcher, founder, and advocate working to open conversations around women’s health, mental health, and other issues that many societies still struggle to discuss openly. Together, we discuss Petra’s research on menstruation and menopause in the workplace in Croatia, and how research can move beyond academia to spark public debate and influence policy discussions.  This episode is especially for anyone sitting with an idea, passion, or frustration they feel called to act on. Petra speaks openly about fear, uncertainty, and the reality of building change without a blueprint, reminding us that confidence is often built through action — and that for global health we have to be willing to challenge what society stays silent about.

No One's Saviour with Laia Serrano Biosca

In the second episode of Global Health Talks: On the Brighter Side, we are joined by Laia Serrano Biosca, founder and CEO of BarcelonActua—a powerful community of more than 13,000 people committed to taking action and supporting vulnerable populations across Barcelona. We explore how BarcelonActua grew from a simple idea into a thriving organization that brings together citizens and volunteers to support refugees, immigrants, and others in need—through everything from meeting basic needs like food and shelter to providing education, scholarships, and long-term integration support. Laia shares her journey of building and leading a purpose-driven organization for over 15 years, reflecting on how embracing growth sometimes requires difficult decisions and change. Throughout the conversation, we reflect on empathy as a skill that should be cultivated from an early age, and how volunteering can challenge prejudice by reminding us that vulnerability is something we all share. We also touch on the contrast between the negativity often amplified in the media and the quieter reality that most people genuinely want to do good—and how collective action can bring that truth to light.

How the Past Shapes Present Action with Dr. Tamara Giles Vernick

In the very first episode of Global Health Talks, we are joined by Dr. Tamara Giles-Vernick to explore why it's important to study infectious diseases through history, human lens and wider contexts to better understand the present. Tamara Giles Vernick shares with us her path into the field and reflects on how well-intentioned volunteering projects can sometimes do more harm than good. We talk about the Sonar Cities project, which works to protect communities in times of crisis, and why mobilizing those who have already lived through emergencies may be one of the most powerful ways to support vulnerable populations. We also reflect on gratitude, career paths, and what younger generations are doing differently to shape a more thoughtful future in global health.
