Joyonna Gamble-George, PhD’16, was raised in rural Alabama and Florida in a family and community where faith, resilience, civic engagement, and education were foundational values. These values were demonstrated, in large part, by her grandmother, a retired elementary school teacher and small business owner who participated in the Civil Rights Movement.
“As a child, I would accompany her as she canvassed neighborhoods to help register African American voters, including elderly individuals who were homebound or physically immobile due to illness,” Gamble-George said. “Because of her, I came to see science as a form of humanitarianism. Science should serve humanity, and knowledge should expand possibility.”
Gamble-George grew up wanting to reduce suffering, expand access to care, and create opportunities for people who have historically been left out of innovation. With a dual undergraduate degree in biochemistry and biology (with honors in mathematics) and a master’s degree in health administration, Gamble-George came to Vanderbilt in 2011, utterly captivated by the human brain and on her path to earn a Ph.D. in neuroscience through her work in the lab of then-Assistant Professor of Psychiatry and Behavioral Sciences Sachin Patel.
What she did not predict, however, was that she would gain more than just scientific training at Vanderbilt: “Vanderbilt deepened my mechanistic understanding of brain function and exposed me to interdisciplinary collaboration, entrepreneurship, and leadership in ways I had not previously imagined,” Gamble-George said.
Today, her work increasingly integrates science, technology, strategy, and entrepreneurship, sitting at the intersection of neuroscience, public health, artificial intelligence, and health equity. To sharpen her entrepreneurial skills and business acumen, she is also completing an executive MBA at Duke University’s Fuqua School of Business.
We had some questions for Gamble-George, and here are her alum answers.
What skills or knowledge gained during your time at Vanderbilt have been most valuable in your current role or industry?
One of the most valuable skills I gained at Vanderbilt was the ability to think mechanistically, to move beyond surface observations and ask why a phenomenon occurs at the cellular and systems levels. Those skills now translate directly into how I approach large-scale human datasets, multi-omics integration, and machine learning analyses.
Equally important was my experience in the Interdisciplinary Graduate Program, which shaped how I think about collaboration across fields. Training within IGP exposed me to diverse scientific perspectives early in my career and reinforced that complex biomedical problems rarely belong to a single discipline. That interdisciplinary foundation prepared me to move fluidly between neuroscience, public health, artificial intelligence, and policy, and to build partnerships across sectors. Learning how to communicate complex science clearly, whether through grants, manuscripts, presentations, or interdisciplinary collaborations, has also been essential.
Today, as I work at the intersection of multiple domains, that ability to translate across disciplines is one of my most valuable assets. Vanderbilt cultivated my confidence to move between sectors without feeling that I was leaving science behind. Rigorous, interdisciplinary training provides a foundation that you can scale.
Can you share a particular challenge you faced during your training at Vanderbilt and how you overcame it? How did this experience contribute to your professional development?
One of the most significant challenges I faced during my training was learning how to persist and thrive in environments that were not always affirming. There were moments when I had to navigate intense competition, limited representation, and experiences that tested my confidence, making me question at times whether I truly belonged in the spaces I had worked so hard to enter. Rather than allowing those challenges to diminish my sense of purpose, I leaned into discipline and clarity. I focused on the quality of my work, the integrity of my data, and the long-term vision I had for my career.
On a mission trip to the Dominican Republic, I was respected for who I was, not how I conformed. I had previously been teased for styling my hair in Bantu knots and it had made me acutely aware of how appearance can influence perception in professional spaces. That experience, however, affirmed something fundamental: Authenticity is strength, not a liability.
That realization became an analogy for my scientific journey. Just as I chose to remain natural and unapologetic in how I present myself, I chose to remain grounded in my identity and purpose within science. I did not need to alter who I was to belong.
Challenges have not derailed my trajectory. They have refined it.
Were there any unexpected twists or turns in your career journey? How did your biomedical education prepare you to navigate those challenges?
There have been several unexpected turns, from co-founding a biotech startup during graduate school to transitioning into science policy at the National Institutes of Health and later stepping into executive leadership roles. None of those paths were linear or planned from the beginning.
What Vanderbilt gave me was adaptability grounded in rigor. Biomedical research teaches one how to troubleshoot when experiments fail, how to analyze data when results are ambiguous, and how to make decisions in the face of incomplete information. That training becomes less about memorizing content and more about cultivating disciplined problem-solving. Those same skills apply seamlessly to entrepreneurship, federal policy work, and organizational leadership.
During my doctoral training, I was accepted into the highly selective 64th Lindau Nobel Laureate Meeting in Physiology or Medicine, and I became the first African American woman to represent the Vanderbilt University School of Medicine. In a small workshop, Nobel laureate Dr. Bert Sakmann asked, “If resources were unlimited, what would you create?” That question shifted my focus from what I would publish to what I would build and ultimately shaped many of the “unexpected” pivots in my career.
Each pivot reinforced a central lesson: Scientific training is not confining; it is expansive. The core competencies of hypothesis-driven thinking, critical analysis, resilience under pressure, and clear communication are transferable across sectors. Vanderbilt prepared me not just to conduct experiments, but to adapt, to lead, and to build in environments that demand both precision and vision, while navigating complexity.
One unexpected chapter in my journey has been public visibility. Through the Lyda Hill Philanthropies’ IF/THEN® Initiative, a life-size, 3D-printed statue of me was featured in national exhibitions, including installations at the Smithsonian, the Cambridge Science Festival, and in Dallas at Love Field Airport and NorthPark Center. A photograph of me is also permanently featured as part of IF/THEN® at the International Museum of Surgical Science in Chicago, Illinois. The #IfThenSheCan exhibit led to national media coverage, including a feature on the Today Show. Somewhere along the way, I even ended up with a Wikipedia page, which still feels somewhat surreal.
What activities organized by Vanderbilt and/or the Office of Biomedical Research Education and Training had the most significant impact on your career path? Were any pivotal moments or decisions in your career influenced by your experiences at Vanderbilt or with BRET?
The BRET Office and the IMSD program had a profound and multifaceted impact on my career trajectory.
Through BRET-hosted workshops, professional development programming, and direct mentorship, I gained exposure to career pathways beyond traditional academia. BRET did not simply prepare me to complete a degree, it prepared me to operate as a professional scientist. Their programming emphasized scientific rigor, ethical research practices, public speaking, and emotional intelligence. I also benefited from workshops on professional etiquette, including networking skills and formal dinner etiquette, which may seem small but are critical when navigating leadership spaces. Those experiences built confidence in settings where presence and communication weigh as much as technical expertise.
BRET’s ASPIRE modules were also instrumental in broadening my understanding of technology transfer and innovation and how entrepreneurship can serve as a vehicle for translating research into societal impact. That exposure laid the groundwork for my later work in founding and leading startups, such as SciX, a biotech startup exploring data-driven and wearable technology approaches to improve chronic health conditions.
I also participated in the Aspire Path in Molecular Medicine and completed the Howard Hughes Medical Institute/Vanderbilt University Medical Center Certificate Program in Molecular Medicine, which strengthened my interdisciplinary training and focus on translational science. BRET programming also introduced me to Vanderbilt’s College Teaching Certificate Program through the Center for Teaching (now part of the Vanderbilt Institute for the Advancement of Higher Education), which deepened my understanding of evidence-based pedagogy and inclusive teaching practices and later informed my work in mentoring students and engaging the public in science.
In turn, the IMSD community provided something equally important: belonging. The bonds formed through shared programming, hiking excursions, and social gatherings created a network of peers who understood the complexities of navigating biomedical training while underrepresented. That support system reinforced resilience and my long-term vision.
BRET’s CV/Resume Drop-In Clinic and the IMSD’s support were also pivotal in my successful application to the AAAS Science & Technology Policy Fellowship. The fellowship reinforced a lesson that continues to guide me: Transferable skills are a scientist’s greatest asset. The ability to analyze data, communicate clearly, synthesize complex information, and build interdisciplinary collaborations applies equally in academia, government, and entrepreneurship.
Vanderbilt created an environment where pursuing policy, entrepreneurship, and interdisciplinary leadership was not viewed as deviation—it was viewed as expansion.
Looking back, what advice you would give to current biomedical students or postdocs based on your own experiences and the lessons you’ve learned along the way?
First, define success for yourself early. Academic culture can sometimes present a narrow definition of achievement centered on publications, grants, and titles. These are important, but they are only part of the picture. Take the time to ask yourself what kind of problems you want to solve, who you want your work to serve, and what kind of life you want to build. Let that vision guide your decisions.
Second, master your fundamentals. Whether you are working at the bench, analyzing large datasets, or developing computational models, depth matters. The rigor you build during your training will become the intellectual backbone that allows you to pivot into other fields. Breadth is powerful, but depth gives you credibility.
Third, embrace interdisciplinary fluency. The future of biomedical science will not live within disciplinary silos. The most pressing health challenges, from chronic disease to health inequities, require collaboration across biology, data science, public health, engineering, and community engagement. Learn how to speak more than one “scientific language.” That skill will make you invaluable.
Fourth, build community intentionally. Mentorship does not have to come from a single individual. Seek out networks, both formal and informal, that support your growth, especially if you are navigating spaces where representation is limited. You are not meant to do this work alone.
Finally, remember that your perspective is an asset. The lived experiences, cultural background, and intellectual curiosities you bring to science shape the questions you ask and the solutions you imagine. Science advances when more voices are included, not fewer. Your training is not just preparing you to generate knowledge; it is preparing you to shape the future of how knowledge is applied. Build boldly. Lead with integrity and never forget why you began this journey.
What’s something fun, quirky, or unexpected about you that people may not know?
Something people may not expect about me is how deeply art and imagination are woven into my life. I paint, and one of my portraits—a depiction of Louis Armstrong playing the trumpet that was inspired by his U.S. postage stamp—was displayed at a U.S. Post Office in Laurel, Maryland. My artwork has also been featured in discussions about integrating art and science by the Aspen Institute [PDF]. I play the alto saxophone and piano and taught myself the flute and violin, although I still need to work on my violin skills. I write poetry. I also love science fiction, historical action romance, and even vampire films.
Long road trips are one of my favorite ways to think, reflect, and recharge. I would rather drive across the country than board a plane, especially if I can sing along as though I were in a musical. In my earbuds, though, I usually listen to podcasts, which lately include business breakdowns and conversations on climate, environmental sustainability, and corporate strategy.
Perhaps most unexpected of all, I have owned exotic pets, including ferrets and even a skunk named Ginger.
