In the quiet corridors of the Broad Institute of MIT and Harvard, Dr. Jason Buenrostro—a scientist already renowned for his revolutionary contributions to genomics—has embarked on a mission that feels less like a typical research project and more like a profound reckoning with his own past.
In early October 2023, the trajectory of Buenrostro’s career was irrevocably altered by a single phone call from the MacArthur Foundation. He had been named a "Genius Grant" recipient, a prestigious honor bestowed upon individuals who show exceptional creativity and promise. For the Harvard professor of stem cell and regenerative biology, the recognition was a "deeply emotional moment." Yet, the $800,000 unrestricted award did more than validate his past work; it provided the financial freedom and psychological security to pivot away from the comfort of his established expertise to tackle one of the most elusive questions in human biology: Why do some individuals thrive in the face of crushing adversity while others succumb to its health consequences?
A Childhood Shaped by Resilience
To understand Buenrostro’s current scientific obsession, one must look at his origins. Born to Mexican immigrant parents in the San Francisco Bay Area, Buenrostro’s early life was marked by the shifting sands of economic precarity. He recalls cycles of living in the garages or living rooms of cousins, witnessing firsthand the erosion of health and opportunity caused by poverty, addiction, and systemic violence.
Despite these environmental stressors, Buenrostro’s household was a sanctuary of love and ambition. His parents, though lacking in material wealth, were adamant about the transformative power of education. He and his siblings stayed out of trouble, excelled in their studies, and ultimately became the first in their family to graduate from college.
As a successful academic, however, the disparity between his own success and the struggles of his peers began to haunt him. "Those of us who grew up poor or are first-generation wonder why we made it and some of our friends and family members didn’t," Buenrostro reflects. "I still have this deep desire to understand why it is that I got out and others didn’t, especially acknowledging that I wasn’t the smartest one."
Chronology: A Career Built on Ingenuity
Buenrostro’s path to the upper echelons of science was defined by an early aptitude for building the tools that define scientific boundaries.
- The Early Years (Santa Clara University): At Santa Clara, near his hometown of Redwood City, California, Buenrostro distinguished himself as one of the institution’s first dual-degree students in bioengineering. While he briefly considered a career as a physician, he concluded that the impact of scientific research—creating the very technologies that allow doctors to heal—offered a broader scope for social good.
- The Stanford Breakthrough (2010s): During his doctoral work at Stanford University, Buenrostro became the inaugural member of a new lab, where he demonstrated an uncanny ability to conceptualize complex systems. He invented ATAC-seq, a groundbreaking method for mapping the epigenome—the chemical "switches" on DNA that dictate gene activity. By making the process faster, cheaper, and more accessible, he provided the global scientific community with a standardized tool for understanding cell behavior.
- The Broad Institute & Harvard (2016–2023): After bypassing the traditional post-doctoral route to become a junior fellow in the Harvard Society of Fellows and the first Broad Fellow, Buenrostro quickly ascended to a faculty position. Over these years, he expanded the capabilities of his tools, integrating spatial information and complex computational modeling.
- The Pivot (2024–2025): With the impetus of the MacArthur award and a $50 million infusion from the Treehouse Family Foundation, Buenrostro shifted his lab’s entire focus. In 2025, he officially launched the Biology of Adversity Project, a multi-disciplinary effort designed to bridge the gap between social experience and molecular biology.
The Epigenetic Imprint: Supporting Data and Mechanisms
Buenrostro’s research rests on a growing body of evidence that external life experiences—war, famine, poverty, and chronic stress—do not merely "happen" to a person; they leave a biological signature.
The biological mechanism, as Buenrostro explains, lies in the interaction between the endocrine system and the epigenome. When a person faces acute or chronic stress, the body releases hormones such as cortisol and adrenaline. These hormones travel through the bloodstream and enter cells, where they interact with the machinery that turns genes on and off.
While this stress response is essential for immediate survival—helping us "fight or flee"—persistent activation can cause long-term alterations in the epigenetic marks on our DNA. These changes can leave an individual more susceptible to cardiovascular disease, autoimmune disorders, and mental health challenges later in life. Current research in the Biology of Adversity Project is specifically investigating:
- Molecular Memory: How stressors in childhood become "embedded" in the DNA of specific tissues.
- Model Systems: Using laboratory models to observe how social isolation and environmental enrichment alter cellular development.
- Human Cohorts: Identifying biomarkers in the blood of trauma survivors that can predict future health risks, potentially allowing for preemptive intervention.
Official Responses and Collaborative Synergy
The scope of this work has required a departure from traditional "siloed" science. By partnering with the Broad Trauma Initiative, led by Dr. Karestan Koenen, Buenrostro has created a pipeline that connects molecular biology with clinical and population-level data.
"Jason has an uncanny ability to find people who can nucleate around the ideas that he wants to push," says Dr. Ravi Raju, a physician-scientist at Boston Children’s Hospital. "He embodies the passion, interest, drive, and curiosity that help our whole community move forward."
The support from the Treehouse Family Foundation has been pivotal. Foundation leaders, recognizing that the "Biology of Adversity" required more than just standard research funding, committed $50 million to ensure the project had the resources for high-throughput, large-scale studies. This is a rare example of a philanthropic entity not just funding a project, but actively collaborating to solve a public health crisis at its molecular roots.
Implications: The Future of Precision Medicine
The implications of this research are profound. Just as cancer researchers revolutionized medicine by moving away from "one-size-fits-all" chemotherapy toward targeted, precision therapies based on the genetic mutations of a tumor, Buenrostro hopes to usher in a new era for trauma survivors.
If we can identify the specific "molecular imprints" of different types of trauma, the possibilities for intervention are transformative. These could range from nutritional supplements designed to support resilience in at-risk children to advanced gene-regulatory therapies that could help "reset" the biological response to past trauma.
However, the path forward is not without its hurdles. Buenrostro openly admits to experiencing "impostor syndrome" and acknowledges that some peers initially viewed his move into neuroscience and social science as "too risky" or "too crazy." His wife, MIT professor Sara Prescott, was instrumental in helping him navigate these doubts, providing him with both the encouragement and the neuroscience expertise necessary to bridge his new field.
For Buenrostro, the Biology of Adversity Project is the culmination of his life’s work. It is the intersection of the technical genius that made him a leader in genomics and the deeply human experience that first led him to the laboratory.
"Fixing the damage of stress is something that keeps me up at night," Buenrostro said during a recent presentation at the Broad. "We hope that the work we’re doing improves our understanding of the shared human experience, and over time not only helps us better understand history, but also helps us build society for a better future."
As he leads his team into this new frontier, Buenrostro remains grounded by the memory of the living rooms and garages of his youth. He is no longer just a toolmaker; he is an architect of a future where the scars of adversity are not just understood, but potentially healed at the very level where they begin: the cell.
