The weight of a shared dream: Reflections on the Quad Fellowship Leadership Summit

On August 4th, the 2025 Quad Fellows were announced, marking one year since I was named a Quad Fellow. Seeing familiar faces in the new cohort, fellow Knight-Hennessy scholars Jocelyn Ricard and Chinmay Sonawane, and that I am now a “senior fellow,” crystallized just how much the year has held, from beachside trips to novel drug design collaborations and building nonprofits together. I keep thinking back to the week that started it all.

In the heart of Washington, D.C., where history and policy collide, the 2024 Quad Fellowship Leadership Summit unfolded as more than an event. It was a gathering of ambitions, a reckoning with purpose. Over several days, scholars, policymakers, and leaders from Australia, India, Japan, the United States, and the newly included Southeast Asian Nations assembled to confront the complexities of a world fractured by inequities yet bound by shared challenges. As one of ten Quad Fellows representing the United States, I was honored to be among the scholars in attendance.

The Quad Fellowship, an initiative supported by the governments of the four nations, seeks to cultivate the next generation of leaders in science, technology, engineering, and mathematics. It aims to foster global collaboration by equipping scholars with the tools to address humanity’s most pressing challenges: climate change, health disparities, technological equity, and more. The fellowship is not just about advancing knowledge but about bridging divides, creating solutions that reflect the interconnectedness of the world we inhabit.

For those of us who walked into those halls, the summit demanded more than intellect. It asked not just what it means to lead in a world defined by interdependence but how science and technology can be used to mend fractures instead of deepening them. It asked not just what can we do but for whom and to what end.

The summit’s discussions brought these questions into sharp focus across storied institutions in Washington, D.C.: the White House, the State Department, and the Australian Embassy.

At the White House, we met with members of the National Security Council, where our conversations spanned topics of critical importance to STEM and national security. We explored how technological advancements can bolster national security while addressing shared challenges, highlighting how science and technology are deeply intertwined with the strategies and priorities of the Quad nations. Of our discussions, the Quad Cancer Moonshot initiative stood out to me as a powerful example of how STEM innovation can address global challenges. Focusing on reducing cancer disparities in the Indo-Pacific through improved healthcare systems and access to treatments resonated deeply with me as I am from Todome Togo, a village over 1000 kilometers from the nearest hospital. As a cancer biologist in the Quad Fellowship, I am eager to contribute to its mission of transforming discovery into meaningful action for equity.

At the State Department, we met a dynamic team of diplomats, scientists, and policy experts working at the intersection of science and international relations. These individuals, from seasoned professionals to recent graduates, illustrated how science diplomacy drives collaboration on global challenges like climate change, health equity, and technology governance. Their work shows the transformative power of combining research with policy, ensuring that scientific discovery directly informs decisions that impact millions. To me, their stories underscored the Quad Fellowship’s mission to connect knowledge with action, reminding us that science must extend beyond the lab to serve a shared global purpose.

At the Australian Embassy, the conversations shifted to the potential of public-private partnerships to tackle global challenges. Ambassadors from Australia, India, Japan, and the United States joined industry leaders, including representatives from Google. These discussions were grounded in the transformative possibilities of collaboration between government, industry, and academia. For me, the presence of Google was particularly compelling. My discussion with their team was on DeepMind’s groundbreaking work in AI, which contributed to this year’s Nobel Prize in Chemistry, directly intersecting with my focus on computational and systems cancer biology. It was inspiring to see how AI can unravel complex biological systems, paving the way for advancements in drug discovery and personalized medicine. Sitting in that room, I felt the convergence of technology and healthcare as more than an abstract ideal. It was a tangible force for change, driven by the partnerships that bring innovation from theory into practice.

This summit was about the people who bring those ideas to life. I felt particularly drawn to the insights of Gabriel Reyes and Maya Varma, Knight-Hennessy scholars and 2024 Quad Fellows. Their scientific pursuits, as much as their leadership styles, embodied the spirit of the programs we share.

Gabriel, a developmental scientist, investigates how poverty shapes the cognitive and behavioral development of children and adolescents. His work challenges us to rethink how science can directly inform solutions to systemic inequities. As the founder of FLi Sci, a nonprofit dedicated to supporting first-generation and low-income students in science, Gabriel’s leadership extends far beyond academia, reflecting a commitment to equity and empowerment.

Maya, a computer scientist, focuses on developing artificial intelligence to address challenges in healthcare. Her projects range from creating innovative diagnostic tools to designing systems that transform patient care. Her research bridges technical ingenuity with practical applications, pushing us to consider how AI can reshape healthcare while centering equity and accessibility.

Seeing Gabriel and Maya engage with the summit’s discussions with scientific rigor and a profound sense of responsibility highlighted the value of combining expertise with empathy. They showed that true leadership in science comes not just from innovation but from fostering connection. Their work and perspectives reinforced the idea that science flourishes when driven by collaboration and shared purpose.

The 2024 Quad Fellowship Leadership Summit highlighted the profound responsibility that comes with the privilege of knowledge. It was a space where boundaries blurred between nations, disciplines, and aspirations, and where the collective potential of science to address global challenges felt within reach. As we left Washington, D.C., I carried with me not only the insights from our conversations but also the urgency to act. The summit reminded me, then and now, that the work of leadership is not about solving every problem but about facing complexity with courage, embracing collaboration, and ensuring that the tools of innovation serve the many, not the few.

Today, I face the future ….. 

Afi Tagnedji (2024 cohort) from Todome, Togo, is pursuing a PhD in cancer biology with a focus in computational and systems cancer biology at Stanford School of Medicine. Her goal is to significantly improve quality of life and treatment for cancer patients globally. 

Knight-Hennessy scholars represent a vast array of cultures, perspectives, and experiences. While we as an organization are committed to elevating their voices, the views expressed are those of the scholars, and not necessarily those of KHS.
