• Nationwide evaluation of disinfection byproducts, epigenetics, and birth outcomes.

  5F31ES037209-02
  Tessa Bloomquist · COLUMBIA UNIVERSITY HEALTH SCIENCES, NY · $41,253 · awarded Jun 3, 2026 · NIH

  Regulated US public water systems are a significant source of chronic exposure to contaminants, including disinfection byproducts (DBPs; total trihalomethanes and haloacetic acids). Prenatal DBP exposure is associated with developmental and reproductive toxicity, though existing epidemiologic evidence in the US is limited to small, regional studies. The US…

• Modeling Intermediate-Level Features in V1 and V2 Using Natural Images

  5F31EY037577-02
  Galen Chuang · UNIVERSITY OF CALIFORNIA BERKELEY, CA · $48,437 · awarded Jun 2, 2026 · NIH

  Project Summary/Abstract The goal of this proposal is to computationally investigate the role of spatial phase in the selectivity and invariance of responses of primary (V1) and secondary visual cortex (V2) to intermediate-level features in natural images. This modeling-driven approach will further our understanding of phase-related computations in V1 and…

• Leveraging in vivo protein tracking to identify novel immune markers associated with obesity driven disease

  5F31DK141247-02
  Michael Banki · SCRIPPS RESEARCH INSTITUTE, THE, CA · $34,114 · awarded Jun 1, 2026 · NIH

  PROJECT SUMMARY. To date, biochemical tools to study secreted proteins’ origins and destinations leading to the discovery of new biomarkers associated with disease are underdeveloped. Deciphering interorgan communication pathways will provide insights into key modulators of obesity driven inflammation. Interorgan dysfunction from overconsumption, hence…

• PreoP-SSI: Prediction and prevention of pediatric surgical site infections

  5F31HD114398-03
  Carrie Chan · UNIVERSITY OF CALIFORNIA, SAN FRANCISCO, CA · $48,207 · awarded Jun 1, 2026 · NIH

  PROJECT SUMMARY Despite evidence that half of all surgical site infections (SSIs) may be preventable, SSIs continue to increase in the United States and are a substantial cause of morbidity, mortality, and healthcare costs. There is a lack of evidence-based guidelines for pediatric SSI prevention. Previous efforts to identify pediatric risk factors to…

• Impact of Developmental Glutamatergic Signaling on Oligodendrocyte Differentiation

  5F31NS139593-02
  Tessa Allen · UNIVERSITY OF COLORADO DENVER, CO · $39,079 · awarded May 29, 2026 · NIH

  Project Oligodendrocytes nervous propagation. involves proliferation development. developing chemogenetically preliminary precursor development of also maturation. early Here elucidate glutamate Summary (OLs) produce myelin, a lipid rich membrane that wraps neuronal axons in the central system to provide them with metabolic and trophic support and allow for…

• Impacts of local government support service expenditures on homicide rates

  5F31MD020274-02
  Jonathan Burke · NEW YORK UNIVERSITY SCHOOL OF MEDICINE, NY · $50,114 · awarded May 29, 2026 · NIH

  Community violence exacts a devastating toll in the United States (US). A promising approach to reduce community violence focuses on investing in meeting the essential needs of communities that suffer from high levels of violence, such as housing, youth programming, and a well-maintained built environment. While these interventions have demonstrated success…

• Equity Implications of Changes in Hospital Market Concentration on Quality of Care and Patient Safety After the Affordable Care Act

  1F31MD020587-01
  Alexander Adia · UNIVERSITY OF CALIFORNIA BERKELEY, CA · $48,437 · awarded May 28, 2026 · NIH

  PROJECT SUMMARY/ABSTRACT (DESCRIPTION) Across the United States, hospital markets are becoming increasingly concentrated via organizational mergers, acquisitions, and closures. Hospital consolidation can reduce competitive incentives, potentially impacting organization behavior in ways that can either improve or worsen quality of care, but there is limited…

• Molecular Reprogramming of Microglia in Neurodegeneration

  1F31AG099702-01
  Leen Aljayousi · ADVANCED SCIENCE RESEARCH CENTER, NY · $34,114 · awarded May 27, 2026 · NIH

  PROJECT ABSTRACT Microglia, the brain's primary immune cells, play various roles in Alzheimer's Disease (AD) with protective and neurodegenerative outcomes. Our lab recently identified a neurodegenerative subset of microglia characterized by the activation of the integrated stress response (ISR), a cellular stress response pathway. Notably, genetic and…

• Electrochemical Fluorination for Organic Synthesis

  5F31GM154474-02
  Jessica Bay · PURDUE UNIVERSITY, IN · $50,114 · awarded May 27, 2026 · NIH

  PROJECT SUMMARY Fluorination of an organic compound affects physicochemical properties, which in medicinal settings perturbs pharmacodynamic, pharmacokinetic, distribution, and/or metabolic profiles both in vitro and in vivo. Thus, the ability to selectively install fluorinated groups, such as sulfonyl fluorides (SO2F) and aryl fluorides (ArF), under mild…

• Identifying metabolic targets to reinvigorate T cell exhaustion

  5F31AI186227-02
  Minsun Cha · JOHNS HOPKINS UNIVERSITY, MD · $50,114 · awarded May 26, 2026 · NIH

  PROJECT SUMMARY CD8+ T cells are a critical component of the adaptive immune system and play an essential role in immune defense against viruses, bacteria, and tumors. To achieve such a critical function in many different contexts, CD8+ T cells have evolved to be highly adaptive by modulating cellular metabolism. Activated effector T cells require high…

• Attenuation of sepsis-induced microvascular permeability and inflammation with the GLP-1R agonist liraglutide.

  5F31HL178162-02
  David Aslaner · VANDERBILT UNIVERSITY, TN · $38,298 · awarded May 25, 2026 · NIH

  Project Abstract Sepsis is a critical problem around the world causing 20% of all global deaths. The lack of effective therapeutics leaves critically ill patients with systemic organ dysfunction often caused by damage to the vascular endothelium. The damage induces micro-vessel dysfunction and increased permeability. Increased permeability can be attributed…

• MRTF-B dependent regulation of adipocyte hyperplasia

  1F31DK145211-01A1
  Scott Connelly · BOSTON UNIVERSITY MEDICAL CAMPUS, MA · $50,114 · awarded May 22, 2026 · NIH

  Project Summary Obesity is one of the most pervasive diseases in the United States and increases the risk of cardiovascular disease, type 2 diabetes, liver steatosis, and certain cancers. Modified diet and exercise can treat obesity but most of these interventions are not sustained, creating an unmet need for pharmacological therapies for obesity or its…
