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.

Since its inception in 1985, the Pew Scholars Program has been a catalyst for innovation, underwriting the creative efforts of researchers at a critical stage in their careers—junior faculty embarking on independent labs and novel projects. The 2025 class forms the 40th cohort of scholars, an elite network now exceeding 1,000 scientists whose collective work spans a remarkable breadth of biomedical disciplines. These scholars gain not only financial support but also access to a vibrant community that encourages multidisciplinary collaboration and idea exchange, vital components in accelerating scientific breakthroughs.

The current group emerges from a competitive pool of 209 nominees, each put forward by leading U.S. academic institutions. Their research portfolios showcase the use of cutting-edge methodologies, including advanced molecular biology, synthetic biology, computational modeling, and state-of-the-art imaging techniques. Their scientific inquiries cover a wide spectrum—from dissecting the complex interplay between the microbiome and host metabolism to unraveling the genetic blueprints shaping neural circuits and developmental processes in the brain.

Several scholars are delving into the intricate molecular interactions underlying infectious diseases. For example, one investigator from Harvard is pioneering studies into the mechanistic interfaces between human cells and emerging pathogens like coronaviruses and simian hemorrhagic fever viruses, using high-resolution structural biology tools to elucidate viral entry and immune evasion strategies. Such work has critical implications for pandemic preparedness and viral therapeutics.

Others focus on immune system dynamics and neural health, notably exploring how brain-resident immune cells contribute to neural development and behavioral outcomes, with an emphasis on sex-specific differences. These investigations employ sophisticated genetic and cellular assays, including single-cell transcriptomics and epigenetic profiling, aiming to untangle how immunity intersects with neurobiology across the lifespan.

A noteworthy cluster of scholars investigates metabolic reprogramming at the cellular and molecular levels. One Berkeley-based researcher is examining the spatial reorganization of subcellular architecture that enables cells to adapt their metabolic pathways—a study that could illuminate fundamental principles of cellular plasticity and identify new targets for metabolic diseases. Complementarily, another scientist at Van Andel Institute is probing the microbiome’s capacity to ameliorate metabolic disorders, decoding the molecular linguistics that allow commensal bacteria to regulate host physiology.

The spectrum of developmental biology is represented too, with research aimed at embryo resilience, maternal environmental impacts on development, and the maintenance of reproductive capacity over extended lifespans, such as in sea stars. These endeavors utilize innovative in vivo imaging, genome editing technologies like CRISPR, and artificial intelligence-enabled data analysis to uncover developmental trajectories and their modulation by extrinsic factors.

Adding to the diversity of cutting-edge science, one scholar is advancing synthetic biology approaches to engineer programmable cis-regulatory DNA elements. This pioneering work seeks to refine gene therapy techniques by controlling spatial and temporal gene expression, a critical step toward precision medicine applications with minimized off-target effects. Meanwhile, others are constructing novel RNA-based therapeutics, designing stable and controllable RNAs with enhanced therapeutic indices and delivery capabilities.

The program also highlights scientists leveraging virtual reality platforms to investigate spatial navigation and memory recall processes in the brain, illustrating how technological integration can revolutionize neuroscience research.
