As a PhD student and a paleobotanist in EARTH, Jerónimo Morales Toledo dedicates his research to understanding the evolution of plants over geological time.
A native of Mexico City, Morales Toledo’s scientific journey has been profoundly influenced by his cultural heritage and early exposure to the natural world. His academic journey started at the National Autonomous University of Mexico, where he completed his undergraduate and master’s degrees. Growing up in the southern part of Mexico City—an area rich in natural wonders—instilled in him a deep appreciation for the environment.
Traveling through the Trans-Mexican Volcanic Belt and into the Valley of Mexico, Morales Toledo recounts how the landscape deeply connected with his sense of identity. "I would often gaze at the majestic volcanoes, Popocatépetl and Iztaccíhuatl, which guarded the valley and sparked my curiosity about the world beyond," he reminisces.
At U-M, Morales Toledo’s research delves into the world of fossil plants, exploring their structure and morphology to uncover their evolutionary history. "I’m fascinated by how plants have shaped the Earth and, in turn, how the Earth has shaped plant evolution," he explains. His studies offer insights not only into past ecosystems but also into contemporary biodiversity and ecological contexts.
Morales Toledo attributes his passion for science to his parents, both ethnobotanists. "They taught me from a young age about the intricate relationships between humans and plants," he shared. These early lessons were reinforced by family trips to the Chihuahuan Desert, sparking his interest in geology and paleontology."When I realized the complexity and beauty of plants, I knew that paleobotany was my calling," he says.
Being Mexican deeply influences Morales Toledo’s perspective as a scientist. "In Mexico, for example, corn was domesticated from its wild ancestor, teosinte, and has since become a central part of our cultural identity," he notes. “This connection is reflected in our food, our celebrations, and even the way we relate to each other. For me, understanding the deep evolutionary history of plants is also a way of understanding ourselves as a society. My heritage constantly reminds me of the rich history that plants have played in shaping human civilization.”
His cultural background offers a unique vantage point: "Growing up in a place with such deep natural and cultural history, I’ve always seen the interconnections between humans, plants, and the Earth," he explains. This perspective reminds him that science is not just about data but also the stories and relationships connecting us to the natural world.
Adapting to the cultural differences between Mexico and the U.S. posed challenges for Morales Toledo, especially in scientific environments. "Sometimes it feels like I have to work harder to prove myself," he admits. But I’ve learned to view these challenges as opportunities for growth. I admire the can-do attitude and boldness I’ve encountered in the U.S., and I’ve learned to blend my own MEX-I-CAN mindset with this American optimism to overcome obstacles in research. It’s taught me that challenges are universal, and finding ways to navigate them makes us stronger.”
Morales Toledo hopes his work will inspire other young scientists, particularly in Mexico, to pursue their passions and recognize their potential contributions to global science. "I want to bridge the gap between Mexican and international research," he says.
Morales Toledo calls for creating inclusive spaces, mentorship programs, and representation in leadership roles to uplift Latinx and Hispanic voices in the Earth and Environmental Sciences. "Fostering an environment where people from all backgrounds feel valued and supported is crucial," he emphasizes.
As he continues his research on plant evolution, Morales Toledo envisions more international collaborations and inspiring students from Latin America to explore careers in paleobotany. "Understanding our past—both as humans and as part of the natural world—can help us shape a better future," he reflects.
Grateful for the opportunity to share his journey, Morales Toledo remains dedicated to uncovering the history of life on Earth and sharing his passion for science with communities worldwide.
