Taking Science out of the Classroom and into the Community

A Bronx, New York native, Deztynee Rivera ‘25PBPM first came to Columbia as a Princeton graduate and neuroscience researcher. However, seeking a career path that would meld her passion for science and her thirst to make a tangible social impact, she found her way to medicine and the Columbia Postbac Premed Program.

As I reflect on my journey, I recognize that it has been shaped by a series of pivotal decisions and experiences that led me toward a career grounded in both intellectual rigor and meaningful impact. At Princeton University, I pursued a degree in neuroscience, initially envisioning a future in academia with the goal of earning a PhD. My fascination with the complexities of the brain and human behavior fueled my academic pursuits, and I thrived on the intellectual challenges the field presented. Yet, despite the academic fulfillment, I often felt that there was a disconnect between my passion for science and my desire to make a tangible difference in people’s lives.

After graduating, I transitioned into the nonprofit sector, joining an organization dedicated to advancing educational equity. This role resonated deeply with me, as I have always believed in the transformative power of education in dismantling barriers. This experience illuminated that my truest fulfillment lies in empowering individuals by providing direct support and fostering opportunities for growth. Thus, this period of reflection solidified my desire to pursue a career that would allow me to directly impact people’s lives in a profound way.

Determined to integrate my scientific interests with my commitment to social impact, I returned to research, joining a neuroscience lab at Columbia University. However, as I immersed myself in the lab, I found myself yearning for something more dynamic and human-centered. It was through my volunteer work at the Comprehensive Psychiatric Emergency Program (CPEP) that everything truly came into focus. Engaging with patients in crisis, hearing their stories, and supporting them through some of their most vulnerable moments, I realized that my aspirations extended beyond understanding the brain to helping those navigating complex health challenges. I found myself deeply fulfilled by the human connection and care that medicine offered—something that research alone could not provide.

With a clearer vision of my future in medicine, a new challenge presented itself as I had not completed all of the requisite premed courses during my undergraduate years. During this time, I turned to my mentors and peers for guidance, which led me to discover the Postbaccalaureate Program at Columbia University. The program not only offered the academic foundation I needed, but it also introduced me to a community of passionate, driven individuals, committed to making a difference in the world.

Enrolling in the Postbac Program was a defining moment in my professional journey. It provided me with the opportunity to reshape my trajectory and fully commit to the field of medicine. Today, I am more dedicated than ever to integrating my passion for science with a patient-centered approach, and I hope to inspire others to take bold steps toward their own transformative aspirations.

What has been your proudest accomplishment at Columbia?

One of my greatest accomplishments was successfully balancing full-time work with the rigorous demands of coursework during my first year in the program. Early mornings and late nights became a constant rhythm in my life. Despite a challenging work environment, I embraced each obstacle, pushing forward with unwavering determination. This experience was critical in refining my time management skills while also underscoring the importance of compromise, resilience, and perseverance. It solidified my commitment to my goals, even when confronted with significant challenges.

Another key highlight occurred when I was invited to share my experience with students attending their first medical school fair. The opportunity to give back in such a meaningful way was incredibly fulfilling. It was an honor to help others navigate an important step in their journey to medicine. I continue to see these students around campus, and am grateful to be a familiar face—someone they can turn to for guidance and support regarding the program.

Who are some people who have contributed the most to your Columbia experience?

A particular highlight of my journey was having Professor Luis Avila as the first Columbia professor I encountered in the classroom. His warmth, generosity, and unwavering commitment to his students made a profound and lasting impact on me. He exemplifies the ideal balance between deep expertise and the ability to convey that knowledge in a meaningful, accessible way—demonstrating the profound influence of education. 

I am also deeply appreciative of the guidance provided by my advisor, Dean Brian Allen, whose support has been invaluable in helping me navigate various challenges, refine my aspirations, and develop clear, actionable plans for moving forward. Furthermore, I am incredibly grateful for the friendships I have formed within the Postbac Program. What distinguishes this experience is the diverse range of fields that each of us has pursued before arriving here. This blend of perspectives has been both enlightening and motivating as it has been a privilege to witness the unique ways in which each of us will contribute to the future of medicine.

What advice would you give to a student who's about to start their GS journey?

There will always be an inner voice urging you to do more, to push yourself further, to never settle. While this drive can be a powerful force in achieving success, it is crucial not to let it overshadow the progress you have already made. In the early stages of any journey, it is easy to feel like you are falling behind if you are not constantly present at every event or seizing every opportunity. However, true growth comes when we focus on what matters most to us, so direct your limited time and energy to pursuits that resonate with your core values and ambitions rather than what you feel obligated to do. Success does not always mean taking every opportunity; sometimes it is about taking the right ones.

Another important thing is to celebrate your wins—no matter how big or small. This journey is challenging enough without adding unnecessary pressure, so take the time to acknowledge your progress and give yourself credit where it is due.  Be proud of yourself for how far you have come, and trust that you have the ability to go even farther.
