Q&A with Marlena Robbins
Marlena Robbins is a Doctor of Public Health candidate at the University of California, Berkeley, and Program Coordinator for the Collective Continuance Fellowship (CCF). Her research examines multigenerational perspectives on psilocybin mushrooms in urban Native communities and the development of the CCF as a model for ethical engagement in psychedelic research. Drawing on implementation science, Indigenous methodologies, and public health prevention theory, she studies how research design, governance, and training structures can shape the future of psychedelic science. She has contributed to tribal engagement strategies for the Substance Abuse and Mental Health Services Administration (SAMHSA) and served on the Colorado Natural Medicine Tribal Working Group.
In addition, Marlena was a co-author on the recently published paper, Indigenous Knowledge Systems & Psychedelic Science: Towards Ethical and Reciprocal Collaboration. BCSP financial support made the publication open-access, and we will continue to support future publications that center Indigenous voices, ethics and knowledge production in the psychedelic field.

Can you tell us a bit about your research and your background in the psychedelic field?
Marlena Robbins
My entry into this work started with building a relationship with the medicine itself. When my dad was diagnosed with cancer, I wanted to understand psilocybin-assisted therapy for end-of-life care to help him with his transition. That experience led me to apply to the Doctor of Public Health program at UC Berkeley, where I began learning about ethnopsychopharmacology and the development of culturally informed psychedelic-assisted therapy for groups that identify with particular cultural traditions.
My public health training pushed me to think beyond individual experiences and toward systems, institutions, and prevention. I started asking broader questions: How do these culturally grounded approaches intersect with Western mental health practices? Where do they align and where do they diverge? And what gets lost, or overlooked, when Western science becomes the primary framework for understanding healing?
How do we find balance, where both Indigenous knowledge systems and Western science are treated as valuable, with tools that can teach and learn from one another?
BCSP
How did you first get involved with the BCSP and the fellowship?
Marlena Robbins
I received the Indigenous Student Research Fellowship through the BCSP and both Dr. Tina Trujillo and Dr. Andrea Gomez became mentors to me. At a time when conversations about commercialization and exploitation of Indigenous communities were becoming more visible in the psychedelic space, it felt meaningful to see an initiative that centered Indigenous presence within an academic research environment.
While the fellowship offered funding, it also signaled that Indigenous perspectives and methodologies belonged in scientific institutions as something worth investing in and learning from.
BCSP
How did this intersect with your dissertation work?
Marlena Robbins
The fellowship supported the early development of my dissertation research. One of my dissertation papers examines the first iteration of the Indigenous Student Research Fellowship and what emerged from that initial cohort. My second paper focuses on the continued development of the fellowship, which is now called the Collective Continuance: Indigenous Knowledge Fellowship. In that paper, I look at how the fellowship might serve as a broader model for the psychedelic field as it begins to ask more foundational questions: What does reciprocity look like in practice? What does ethical research actually involve when Indigenous knowledge systems are engaged? And how can Indigenous ways of knowing exist alongside Western science without being extracted, simplified or translated only on Western terms? This felt especially urgent in the psychedelic field, where interest is accelerating faster than shared ethical infrastructure.
BCSP
Tell us about your new role as the Collective Continuance: Indigenous Knowledge Fellowship program coordinator at the BCSP.
Marlena Robbins
I come into this role as a student first. I’m still learning, and I’m careful not to position myself as an expert. I’m holding this role as a doctoral candidate applying what I’ve learned over the past four years, and as a Diné woman carrying lived experience shaped by how and where I grew up.
My intention is to help center Indigenous knowledge systems within psychedelic science because the field feels lopsided. Western scientific methods dominate, even when the medicines being studied come from Indigenous context with their own epistemologies and ethical frameworks. Part of my role is to help introduce these paradigms thoughtfully and gently while also asking the scientific community to reflect on its assumptions about what counts as valid knowledge.
There are ways of knowing that have been carried for thousands of years. The question I keep returning to is how do we find balance, where both Indigenous knowledge systems and Western science are treated as valuable, with tools that can teach and learn from one another?
BCSP
Who else is shaping the fellowship?
Marlena Robbins
We are working with a focus group of six Indigenous advisors who are helping to guide the fellowship’s design. We’ve shared insights from interviews with previous cohort members, conversations with BCSP staff and reflections from the fellowship’s earlier leadership, including Dr. Gomez, Dr. Trujillo, Dr. David Presti and Dr. Dacher Keltner.
The advisors have been generous with their time, energy and ideas. Then the pilot cohort will also play an active role by testing the partnerships that we’re building, allowing us to learn from how the fellowship functions in practice and not just in theory.
BCSP
Tell us about the upcoming cohort of fellows.
Marlena Robbins
The pilot cohort will include two fellows. We’ll invite them to share their work and to help further shape the fellowship by reflecting on what felt supportive, what didn’t work as intended and what needs rethinking. This phase is intentionally iterative. The fellows are seen as contributors and co-designers of the program’s evolution.
BCSP
The fellowship centers expertise, lived experience and relationship-based governance rather than relying solely on traditional academic hierarchy. Can you speak to the power of structuring the program that way?
Marlena Robbins
The fellowship invites collaboration across roles including Indigenous researchers, advisors, scholars, scientists and traditional practitioners, all with space to lead and design. There is an Indigenous advisory council and there are the fellows, who are UC Berkeley students. Some may be Indigenous and some may not, but all are engaging seriously with the intersection of Indigenous knowledge systems and psychedelic science. Many fellows have been trained within a narrow scientific framework. This fellowship asks them to learn additional methods shaped by Indigenous methodologies, data sovereignty and ethical research practices. We also prioritize partnerships with Indigenous-led organizations that already hold this knowledge, instead of asking institutions to reinvent it. This approach is intended to prevent extractive research relationships, misuse of Indigenous knowledge and institutional practices that reproduce harm even when intentions are good.
BCSP
How does your experience as a doctoral student shape how you’re approaching the fellowship?
Marlena Robbins
My experience as a doctoral student strongly shapes how I approach this fellowship. Early-career researchers often face foundational questions such as how to refine research questions, select methods, navigate Institutional Review Board (IRB) processes, and understand the responsibilities that come with working across knowledge systems, questions I encountered firsthand when beginning my own multigenerational research.
The fellowship is designed as an added layer of support for scholars whose training may not fully prepare them to engage Indigenous knowledge systems. For example, if a researcher hopes to work with Indigenous elders around psychedelic medicines, such as engaging Mazatec communities in conversations about psilocybin mushrooms, the research questions extend beyond methodology. How are relationships built over time? How is trust established? Who guides the research process? And who holds authority over how knowledge is shared and used? The fellowship creates space for researchers to think through these questions with careful approaches that are responsive to community contexts.
BCSP
How do you think about the fellowship playing a broader role in the psychedelic field?
Marlena Robbins
At a systems level, change begins upstream. If we engage students early and support them in developing research that takes Indigenous-centered perspectives seriously, the fellowship functions as a form of primary prevention at the level of research practice. Operating across individual, institutional and community contexts, it intervenes before extractive or unethical approaches become embedded, supporting research relationships built on accountability, responsibility and respect. This work is informed by socio-ecological approaches to prevention and public health ethics, which emphasize upstream intervention, systems-level change and the prevention of structural harm.
