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.

Among the recipients, Amelia Douglass, a neuroscientist originally from Australia, is set to focus her research on the multifaceted ways in which animals respond to stress. By examining both behavioral and physiological adaptations, Douglass aims to elucidate the mechanisms that underlie survival in the face of environmental challenges, such as predation, extreme temperatures, and infectious threats. Her prior experience as a postdoctoral research fellow at Harvard Medical School, coupled with her recent appointment at ISTA, paints a picture of a researcher poised to make significant contributions in her field.

Douglass’s project, titled “The hypothalamic control of behavioral and physiological adaptations to stress,” succinctly dubbed “HypoAdapt,” seeks to peel back the layers of complexity surrounding the brain’s role in stress responses. Mice will serve as the primary model organism for this research, as they provide an excellent analog for studying the intricacies of stress management in biological systems. Douglass’s research team will investigate how the brain orchestrates quick responses to threats while also probing the lasting effects that chronic stress may have on behavior and physiologic functions.

In her own words, Douglass states, “We want to understand the brain-driven adaptations to these threats at two different levels: First, we want to know how these responses are so rapidly executed when a challenge is encountered.” This research is of paramount importance not only for understanding animal behavior but also for exploring the implications for human health, particularly in individuals grappling with anxiety and stress-related disorders. The potential translational impact of this work underscores the relevance of her research to the broader fields of clinical psychology and neuroscience.

Beyond her immediate research goals, Douglass hopes to use the funding to expand her team, bringing additional postdoctoral fellows and PhD students on board. The financial backing from the ERC will allow her to explore more ambitious questions than she could otherwise undertake, fostering an environment of innovation and depth in her laboratory. Coupled with ISTA’s robust scientific infrastructure, the potential for significant discoveries increases exponentially, promising to unlock new insights into the ways that living organisms manage stress.

Parallel to Douglass’s promising endeavors, Ylva Götberg, an astrophysicist from Sweden, is embarking on her own ambitious journey, equipped with an ERC Starting Grant to investigate the intriguing phenomenon of binary-stripped stars. Currently, Götberg’s work is poised to reshape our understanding of stellar evolution. Her project, “The Role of Binary-Stripped Stars: from Atomic Scales to Cosmic Dawn,” unravels the dynamics of these celestial bodies that, until recently, were relegated to theoretical discussions.

To clarify, binary-stripped stars refer to pairs of stars wherein one star siphons the hydrogen-rich envelope from its partner, ultimately exposing the helium core. Götberg’s research holds the potential to fill a notable gap in stellar astrophysics, as it is estimated that nearly one-third of all massive stars will undergo this transformation. Importantly, these stripped stars are believed to play critical roles in the genesis of hydrogen-poor supernovae and are fundamental to our understanding of phenomena such as gravitational waves, which result from neutron star mergers.

Götberg’s journey has been remarkable, having completed her PhD in the Netherlands before completing a NASA Hubble Postdoctoral Fellowship in the United States. Her recent appointment to ISTA in 2023 represents a pivotal moment in her career, and her recognition as one of TIME magazine’s 100 Emerging Leaders in 2024 underscores her promise in the competitive field of astrophysics. She reflects on the groundbreaking research ahead, asserting, “With us having recently confirmed their existence, theoretical models can now face reality and observational benchmarks.”

By leveraging upcoming data from major space missions, such as the ultraviolet space telescope UVEX and the laser interferometer LISA for gravitational waves, Götberg and her team will explore the properties and behaviors of stripped binaries in unprecedented detail. The intersection of theory and observation will allow them to pose critical questions about the evolution of binary star systems and to gather vital metrics related to stellar winds and mass transfer efficiencies.

The success of ISTA stands as a testament to its exemplary research environment; since its inception in 2009, it has grown to become a beacon of scientific excellence in Europe. With a striking 47% success rate in securing ERC frontier grants—substantially higher than the broader average—ISTA produces a remarkable workforce of researchers, with 82% of its professors achieving at least one ERC grant. Such achievements spotlight the institute as a critical player in both national and international scientific landscapes.

As the world enters a new era of scientific exploration, the research undertaken by Douglass and Götberg signifies a critical intersection of neuroscience and astrophysics, uniting seemingly disparate scientific disciplines under the universal quest for knowledge. Their findings may not only unravel the complexities of animal behavior and cosmic phenomena but also provide much-needed insights into the profound questions surrounding life, survival, and the universe’s grand design.

Science knows no bounds, and the stories of Douglass and Götberg represent just the tip of the iceberg in our understanding of both animal and cosmic realms. As they embark on their respective projects, the scientific community eagerly anticipates the revelations that lie ahead, which may well alter our perceptions about stress, survival, and the intricate dance of celestial bodies shaping our universe.
