In a remarkable advancement within the field of immunology, Ana Campos Codo, a promising doctoral student at the Weill Cornell Graduate School of Medical Sciences, has been named a 2025 Howard Hughes Medical Institute (HHMI) Gilliam Fellow. This prestigious accolade marks a pivotal moment not only in her burgeoning scientific career but also for the broader scientific community focusing on immune system dysfunctions and autoimmune diseases. As a recipient of this highly competitive fellowship, Codo gains invaluable support allowing her to delve deeply into the molecular underpinnings of autoimmune pathology through innovative and technically rigorous research.
Codo is pursuing her Ph.D. in the Immunology and Microbial Pathogenesis program, an area that integrates cutting-edge immunological concepts with the complexities of microbial interactions and host responses. The HHMI Gilliam Fellowship program is renowned for empowering early-career scientists through substantial financial backing—$65,000 annually for up to three years—while fostering a mentorship model designed to cultivate inclusive and enriching academic environments. Her selection among 30 students nationwide underscores the exceptional quality and potential impact of her research.
Under the guidance of Dr. Justin Perry, an assistant professor specializing in immunology and microbial pathogenesis at the Weill Cornell Graduate School of Medical Sciences and the Sloan Kettering Institute, Codo’s project centers on a mechanistic pathway known as efferocytosis. This physiological process involves specialized immune phagocytes tasked with clearing over 200 billion senescent or apoptotic cells daily, thereby maintaining tissue homeostasis and preventing unwarranted inflammatory responses. Disruptions in this cellular clearance system have been implicated in the pathogenesis of multifaceted autoimmune disorders, including systemic lupus erythematosus (SLE).
Her doctoral research approaches efferocytosis through a unique lens: the role of chloride ions in regulating this vital process. Traditionally, the field has concentrated on protein mediators and signaling cascades within efferocytosis, but Codo’s exploration into ionic contributions represents a novel frontier. Chloride ions, essential for cellular osmotic balance and signal transduction, may influence phagocyte function and apoptotic cell recognition, suggesting new molecular targets for therapeutic intervention. Dr. Perry emphasized that examining chloride’s involvement could revolutionize our understanding of how defective clearance precipitates systemic organ damage typical of multi-organ autoimmune diseases.
The significance of Codo’s work cannot be overstated. By dissecting ion channel dynamics and their integration into immune cell signaling pathways, her research propels the scientific community toward untangling the complex etiology of autoimmunity. Moreover, this project provides a foundational framework for exploring potential pharmacological strategies aimed at restoring proper efferocytic function, thereby mitigating autoimmune flare-ups and progression.
In addition to the scientific merits of her research, the HHMI Gilliam Fellowship fosters vital professional development. Dr. Perry, who also mentors another Gilliam Fellow from the 2023 cohort, participates in a specialized yearlong mentorship skills development program. This component underscores the program’s holistic approach to nurturing not just scientific innovation but also leadership and communication within the STEM fields.
Codo’s journey from São Paulo State University, where she embarked on her academic path in immunology, to earning a Master of Science in genetics and molecular biology at the University of Campinas, before joining Weill Cornell, reflects an inspiring trajectory fueled by determination and intellectual curiosity. As the first person in her family to pursue a scientific career, she embodies the increasing diversification of the biomedical research workforce and demonstrates the transformational power of educational opportunities.
Her commitment extends beyond laboratory walls. Recognizing the importance of representation, Codo actively leads outreach initiatives designed to engage high school students from underrepresented communities in science. These programs seek to dismantle barriers to STEM education and inspire the next generation of scientists from diverse backgrounds, a mission well aligned with HHMI’s dedication to inclusivity.
The networking opportunities presented by the Gilliam Program are equally invaluable. Annual gatherings convene Gilliam Fellows along with HHMI Investigators—many of whom are Nobel laureates—providing an unmatched platform for intellectual exchange and collaboration. Such interactions enrich fellows’ perspectives, expand their academic networks, and foster professional growth.
Codo expressed excitement about the fellowship’s recognition of individual scientific journeys, emphasizing how this validation bolsters confidence and motivation during the demanding Ph.D. process. “This award values your path, and it’s reassuring to know they believe in me,” she remarked, highlighting the program’s role in affirming diverse trajectories within science.
Dr. Perry echoed this sentiment, noting the exceptional prestige of the Gilliam Fellowship and the merit in Codo’s selection. He lauded her innovative approach and tenacity, qualities that will undoubtedly contribute meaningfully to the field’s advancement. Her work offers a fresh paradigm through which the scientific community can interrogate the elusive mechanisms driving autoimmune disease, ultimately fostering the development of novel diagnostic and therapeutic avenues.
Together, the mentorship framework, funding, and collaborative environment provided by HHMI aim to catalyze transformative research outcomes. Codo’s chloride ion-focused investigation into efferocytosis stands as a beacon of this vision, intertwining deep technical inquiry with a commitment to impact and inclusivity in biomedical science.
