This initiative stands as a testament to Pew’s commitment to strengthening scientific bonds between North and South America, providing rigorous mentorship and funding opportunities to extraordinary early-career investigators. The program’s structure not only supports groundbreaking research but also encourages returning fellows to reinvest their enhanced expertise into Latin America’s biomedical research infrastructure. In fact, close to seventy percent of previous participants have elected to establish their own laboratories back home, substantially enhancing the region’s capacity for innovation and scientific discovery.
The scientific inquiries undertaken by the 2025 fellows span a broad spectrum of biomedical challenges. Among the topics addressed is the exploration of how glioblastoma multiforme—the most aggressive and treatment-resistant type of brain tumor—develops metabolic adaptations to evade the cytotoxic effects of radiation therapy. Understanding these adaptive mechanisms at the molecular and metabolic level could revolutionize current therapeutic approaches and improve patient prognosis.

Equally compelling are investigations focusing on neural plasticity and repair. One fellow anticipates illuminating the molecular pathways through which the nervous system remodels itself post-injury, a critical area of study with profound implications for neuroregeneration and recovery following trauma. This research could uncover new avenues for developing regenerative therapies for neurodegenerative diseases and spinal cord injuries.
Another vital research avenue addressed by the fellows involves immunomodulation in the context of pain—a particularly understudied phenomenon during pregnancy. Chronic pain severely undermines quality of life, and the newly funded study aims to unravel how the maternal immune system modulates pain signaling, potentially identifying novel targets for therapeutic intervention that do not compromise fetal health.
Zika virus pathogenesis is a recurrent theme among many fellows, with two projects dissecting how this flavivirus disrupts normal brain development during pregnancy. One project focuses on the second trimester cerebral cortex’s development, elucidating viral interference with neuronal progenitor cells and cortical layering. Another complementary study delves into the genetic regulatory networks essential for brain development, probing how Zika virus infection causes neurodevelopmental disorders by perturbing these intricate networks.
In the realm of metabolic biochemistry, attention is directed towards selenium metabolism, an essential micronutrient implicated in antioxidant defense and thyroid function. Exploring the molecular pathways governing selenium utilization in cancerous cells could reveal metabolic vulnerabilities that might be exploited for targeted cancer therapies.
In cardiovascular developmental biology, one fellow investigates the electrical properties of cardiac tissue, particularly membrane potential dynamics. This research scrutinizes how ionic distributions across cardiomyocyte membranes orchestrate morphogenetic processes during heart development, offering potential insights into congenital cardiac defects.
Additional studies include evaluating cellular adaptations to hypoxia in the brain, which are critical for understanding stroke resilience and neurodegenerative conditions. Furthermore, investigations are underway into the mechanisms by which bacterial small RNAs regulate iron homeostasis, a process fundamental to bacterial survival and pathogenicity, and with implications for antibiotic resistance.
The mentorship guiding these investigations includes luminaries such as Dr. Sarah McMenamin at Boston College, Dr. Christian Mosimann at the University of Colorado School of Medicine, and Dr. James Olzmann at the University of California, Berkeley. Many mentors bring rich experience as previous Pew scholars themselves, reinforcing a vibrant academic lineage that nurtures cutting-edge science.
The Pew Charitable Trusts underscores that this assembly of fellows embodies the essence of scientific curiosity and transformative potential, promising significant contributions to biomedical sciences globally. These young researchers not only push the boundaries of their respective fields but also strengthen the scientific fabric linking Latin America with global innovation hubs, a synergy critical for addressing complex health challenges of the 21st century.
Backed by generous funding and exceptional mentorship, this new wave of Pew Latin American Fellows is poised to make lasting impacts in cancer biology, neurodevelopment, immunology, infectious disease, and beyond. Their research will illuminate fundamental biological processes while fostering an international culture of scientific excellence and collaboration.
