New Voice for Contemplative Science Podcast

Phil Walker sits across from David Creswell in the studio where 84 episodes of the Mind & Life Podcast have been recorded over the last five years. The show is passing the microphone. Wendy Suzuki, who brought the program to life and shepherded its guests through deep dives into contemplative science, neuroscience, and the nature of human transformation, is stepping back. And stepping in is Creswell—a health psychologist at Carnegie Mellon, chief of science at Equa Health, and one of the field's most rigorous researchers into how meditation actually changes the brain and the body. For listeners who encounter Creswell for the first time in this role, the stakes of the transition become clear almost immediately: this is not a changing of the guard so much as a deepening of the inquiry.

Where Psychology and Neuroscience Converge

Creswell's home base, as he describes it, is experimental health psychology—a discipline concerned with how thoughts, feelings, and behaviors shape human suffering and fulfillment. But his path to the host chair has required him to live at the borders between fields. After earning his PhD in social and health psychology from UCLA in 2007, he began mapping the mechanisms by which mindfulness meditation transforms experience. That work pulled him into neuroscience, where neuroimaging offered one lens on brain activity. It also pulled him into psychoneuroimmunology, the study of how the brain and immune system communicate through the stress response and beyond.

What matters most, Creswell suggests, is not the discipline itself but the approach: adopting what he calls "different lenses and different ways of knowing people." Mind & Life, he notes, has always worked at the boundaries between domains—between contemplative science and contemplative practice, between first-person phenomenological observation and third-person empirical measurement. To be a good contemplative scientist, he argues, requires holding all of these ways of knowing at once.

Yet something has shifted in his own work over the past decade. The early focus on biological mechanisms—the mapping of brain regions, the tracing of immune markers—has evolved. "A lot of my work in the last 10 years has really focused on translation," Creswell tells Walker. The question now is not just how meditation works in the brain, but how these insights can scale into programs that move people and systems at population level.

Why Live Training Teaches What Apps Cannot

That evolution matters to how the next season of the podcast will unfold. One of Creswell's recent studies compared the impact of live, group-based meditation training against app-based learning—the kind of on-demand practice that has become ubiquitous in digital wellness. The findings surprised some in the field. Apps are valuable, he emphasizes. They expand access. But they miss something essential that happens in the room with other people, in real time, guided by a living teacher.

The difference shows up in measurable ways. When Creswell's team tracked where the most significant changes in mindfulness skills actually occur, they discovered that the deepest learning happens not in the comfort of solo practice but in the difficulty of group work. "Doing this study with live group-based meditation training," Creswell explains, revealed that repeated engagement in a shared container builds something that an app—no matter how well-designed—cannot replicate. The practice of being open and receptive alongside others, of moving through resistance together, creates a different quality of transformation.

This finding touches on something contemplative traditions have always understood but that modern neuroscience is only now beginning to articulate: the social dimension of practice is not incidental to meditation. It is central to how it works.

The Hardest Moments as the Real Training Ground

Another insight Creswell has been exploring involves the relationship between difficulty and growth. In conversations with long-term meditators—people who have spent weeks on silent retreat—a pattern emerges. When he asks what these practitioners actually learned, what shifted in their understanding, they often point not to moments of clarity or peace, but to moments of resistance. The times when the mind would not settle. The times when old patterns of reactivity surfaced. The times when the practice felt like it was failing.

"The hardest moments in meditation may be where the real training happens," Creswell suggests. If we think about practice that way, it reframes what an effective meditation looks like. It is not primarily a state to achieve. It is a capacity to develop—the capacity to be open and receptive even when the mind resists, even when the body aches, even when nothing feels like it is "working." This shifts the entire enterprise. A busy mind is no longer a failure of meditation. It is an invitation to practice.

The implications extend beyond individual retreat experience. Creswell has been working with a broad range of populations—clinical and non-clinical, diverse in age and circumstance—and this understanding shapes how he designs interventions. If the juice is in the difficulty, then the program must not aim to eliminate resistance but to build capacity to move through it with intention and care.

Scaling Wisdom into Systems

Much of this recent work connects to questions about how contemplative approaches can inform larger systems. Creswell has been thinking deeply about systems change—about how the skills cultivated on a meditation cushion might translate into how organizations, communities, and institutions operate. The work is nascent, but the direction is clear. Contemplative science is maturing. When Creswell looks at the field now, he sees not a marginal experiment but a set of practices and insights ready to reshape how we address collective problems.

This is the vision Creswell brings to the host role. The Mind & Life Podcast, over its first five years under Wendy Suzuki's stewardship, became known for the depth of its conversations—for the willingness to sit with a topic long enough for real understanding to emerge. Creswell intends to honor that legacy while pushing the inquiry forward, toward questions about scaling, systems, and how contemplative wisdom can bridge communities and populations that have been divided or fragmented.

A Season of Deepening Inquiry

In the conversation, Phil Walker—who has been the behind-the-scenes architect of the show's production, the "village" that lifts each episode—poses a question about what listeners can expect. Creswell is direct: the season will explore the intersections between individual practice, scientific understanding, and collective transformation. It will feature voices from contemplative teachers, neuroscientists, systems thinkers, and practitioners who are working at the boundaries where real change happens.

He also makes space for something that the previous iteration of the show did beautifully: the extended dialogue that allows both host and guest to think out loud, to follow ideas where they lead, to hold complexity without rushing to resolution. "Podcasts are really great about going deep with topics," Walker observes. Creswell agrees and means to leverage that capacity fully.

What also becomes clear in this opening conversation is the gratitude Creswell carries toward those who came before—toward Wendy Suzuki for establishing the show's quality and depth, toward Jamie Bristow for the systems change mini-series earlier in the year, toward Erin McCarthy and Susan Bauer and the entire Mind & Life organization for the scaffolding that makes this work possible. This is not a clean handoff but a continuation, a deepening, a next chapter written by many hands.

Where to go from here

For those interested in following Creswell's work prior to this hosting role, his 2023 guest appearance on the Mind & Life Podcast—linked in the show notes—provides essential context on his research trajectory and the questions that have animated his career. The new season launches with a different energy: not an introduction to a guest expert, but an invitation into a host's questions about what contemplative science knows, what it is still learning, and how wisdom can move from the meditation cushion into the systems and communities where we all live.
