From academia to a leading role in the pharmaceutical industry, Dr. Magdia De Jesus has carved a remarkable career path. As the Director of Scientific Strategy and Portfolio Lead in Pfizer’s Chief Medical Office, Dr. De Jesus has made significant contributions to vaccine research and development, inspiring future generations of scientists along the way.
Early Life & Education
Born in Utuado, Puerto Rico, Dr. De Jesus moved to New York City as an infant, growing up in the vibrant community of “El Barrio” in Harlem. Raised in a bilingual environment, she embraced both Spanish and English languages, fostering a deep appreciation for her cultural roots. From a young age, Dr. De Jesus was captivated by science, driven by a fascination with the mechanisms and tools that shape medicine and patient outcomes.
Her academic journey began with a bachelor’s in biology, supplemented by a minor in sociology. She pursued further studies with a post-baccalaureate in biochemistry and microbiology, eventually earning a PhD in microbiology and immunology. After completing two post-doctoral fellowships in emerging infectious diseases (EID) and immunology, she landed a joint appointment from the New York State Department of Health and the State University of New York (SUNY) at Albany, where she established her own research laboratory focused on developing prototype vaccines for oral delivery
The Transition to Pfizer
In December 2019, Dr. De Jesus made a pivotal career move by joining Pfizer’s Vaccine Research and Development unit. Her transition from academia to the pharmaceutical industry was driven from a desire to see vaccines research translated into real world solutions that could reach patients. Within months of joining Pfizer, the world was engulfed by the COVID-19 pandemic. Dr. De Jesus and her colleagues worked tirelessly to develop a COVID-19 vaccine and oral treatment—a period she describes as both challenging and immensely rewarding.
Her passion for Pfizer’s innovative pipeline led her to transition to the Chief Medical Office in 2021, where she now contributes to the scientific portfolio across the entire Pfizer enterprise. Currently, she is also pursuing an MBA, leveraging Pfizer’s Educational Assistance Program to further her understanding of the intersections between science, medicine, technology and business.
Professional Accomplishments
Dr. De Jesus finds immense fulfillment in her role at Pfizer, particularly in the opportunity to collaborate with colleagues across various disciplines and global business units. One of her most notable accomplishments is the establishment of a framework for partnerships between Pfizer and academic institutions, which has bolstered the company’s research initiatives.
But her most impactful contribution thus far is the launch of the Pfizer School of Science. This program aims to inspire the next generation of scientists by hosting middle school students from the NYC Public School system for hands-on, science-based learning experiences. Dr. De Jesus adapted the first two lesson plans in microbiology and immunology she had originally developed for the Rise High Program and provided the content to the Pfizer School of Science which serves underrepresented and economically disadvantaged students in Schenectady, NY. Since its inception, the Pfizer School of Science has welcomed over 7,000 students.
Advocacy & Mentorship
Dr. De Jesus’s commitment to diversity, equity and inclusion (DEI) is evident in her active involvement in Pfizer’s DEI initiatives. She has been influential as a mentor to many colleagues from underrepresented groups, including within the Pfizer Latino Community Colleague Resource Group (CRG). Pfizer’s recognition as a Top Hispanic Employer by DiversityComm Magazine showcases the impact of such initiatives.
Reflecting on her experience as a Latina in the workforce, Dr. De Jesus acknowledges the challenges but emphasizes the importance of embracing them as opportunities. She advocates for the importance of self-advocacy, building trust and acting with integrity. Her personal journey underscores the value of mentorship and community support, encouraging others to find mentors and join employee resource groups to foster a sense of belonging and professional growth.
Looking Ahead
As Dr. De Jesus continues to advance her career at Pfizer, her future goals remain focused on the intersections of science, medicine, technology and business. Her dedication to fostering the next generation of scientists and her unwavering commitment to DEI initiatives ensure that her impact will be felt for years to come.
