In a groundbreaking announcement from the Salk Institute for Biological Studies, Assistant Professor Deepshika Ramanan has been honored as a Rita Allen Foundation Scholar for 2025. This prestigious recognition spotlights early-career researchers whose work is poised to revolutionize biomedical science and improve human health on a global scale. The Rita Allen Foundation Scholars program, known for its rigorous selection process, awards up to $110,000 annually over five years to propel innovative thinking in neuroscience, cancer biology, immunology, and pain research.
Deepshika Ramanan’s research embodies innovation at the interface of immunology and maternal health, with a specialized focus on the intricate communication networks between the gut and mammary glands. Unveiling the mechanisms through which maternal immune cells interact with and support lactation, her work leverages advanced multi-omics technologies to dissect cellular and molecular pathways that govern the transfer of immunity from mother to infant via breast milk. This area of research holds profound implications for understanding how lifelong health trajectories and disease susceptibilities may be influenced during this early window of immune programming.
The maternal-infant immunological dialogue remains a frontier in biomedical science, complicated by the dynamic environment of lactation and the multifaceted contributions of maternal microbiota, immune signaling molecules, and breast tissue physiology. Ramanan’s integrative approach, combining single-cell sequencing, proteomics, and metabolomics, has begun to reveal how specialized immune cells within the mammary gland orchestrate both protective antibody production and the modulation of inflammatory responses crucial for neonatal defense and maternal tissue homeostasis.

Ramanan’s choice to investigate underappreciated aspects of immunology highlights a paradigm shift in understanding systemic immunity through localized, tissue-specific pathways. Her work sheds light on how maternal immune adaptations during lactation not only provide passive immunity but also actively shape the neonate’s developing immune system, potentially influencing susceptibility to infections, allergies, and autoimmune disorders later in life. Such insights underscore the long-term impact of maternal health on population-wide public health outcomes.
Her research trajectory was honed through rigorous academic training, earning a bachelor’s degree in cell and molecular biology from Winona State University and a PhD in immunology and inflammation from New York University. Ramanan’s previous accolades, including the V Scholar Award from the V Foundation for Cancer Research and the Damon Runyon Dale F. Frey Breakthrough Scientist Award, underscore her exceptional contributions to cancer immunobiology and inflammatory research prior to this current focus.
This recognition by the Rita Allen Foundation comes during a critical juncture in biomedical science, as traditional research paradigms evolve toward multidisciplinary, system-wide investigations. Elizabeth Christopherson, president and CEO of the Rita Allen Foundation, emphasized the importance of fostering pioneering scientists like Ramanan, who pursue novel biological questions under challenging conditions. Such research promises to illuminate unexplored immunological pathways with potential to transform preventive medicine and therapeutic strategies.
Technological advances in multi-omics have opened new vistas for deciphering cellular heterogeneity and signaling cascades in complex tissues, a methodological boon that Ramanan has adeptly harnessed. Her laboratory’s integration of transcriptomic and proteomic datasets from mammary gland tissue during lactation equips researchers with unprecedented resolution, allowing identification of rare immune cell subsets and their dynamic functional roles.
Moreover, Ramanan’s investigations extend beyond descriptive immunology to functional validation using in vivo models. By manipulating specific immune pathways and maternal microbial communities, her work elucidates causal mechanisms through which maternal immunity supports neonatal development. These findings have profound implications for developing interventions to optimize maternal health, enhance passive immune transfer, and potentially shape neonatal microbiota seeding.
The Salk Institute, renowned for its pioneering contributions to neuroscience, cancer biology, and immunobiology, provides a nurturing environment for innovative science. Founded by Jonas Salk, whose polio vaccine revolutionized public health, the Institute continues this legacy through laboratories like Ramanan’s that fearlessly tackle challenging biological questions. This new appointment as a Rita Allen Foundation Scholar amplifies the visibility and impact of Ramanan’s research within the scientific community and beyond.
Ramanan’s work intersects with multiple critical domains in life sciences, including obstetrics, immunology, microbiology, and public health. The implications of her research resonate within clinical disciplines related to prenatal and postnatal care, offering scientific foundations for improved breastfeeding strategies and maternal-neonatal health policies. Additionally, her focus on immune-microbiota interactions aligns with broader efforts to decode the human microbiome’s role in disease resistance and health maintenance.
As the biomedical field braces for complex challenges such as emerging infectious diseases, immune dysregulation, and chronic inflammatory conditions, the contributions of scholars like Ramanan offer a beacon of hope. The convergence of cutting-edge technology, sophisticated immunological theory, and translational applications embodied in her research models the future direction of personalized medicine and systems immunology.
The Rita Allen Foundation Scholars program’s investment in Ramanan’s research underscores a broader commitment to fostering scientific innovation that promises tangible benefits for millions. By elucidating how maternal immunity is harnessed and transmitted through lactation at the molecular and cellular levels, this work opens new horizons for improving maternal-child health worldwide, ultimately influencing disease prevention paradigms across the lifespan.
Subject of Research: Maternal immunity and its transmission through lactation; immunological communication between gut and mammary gland using multi-omic approaches.
