Nyangahu Lab Members

Osagie Eribo, PhD

Postdoctoral Associate

Osagie earned his PhD in Molecular Biology from Stellenbosch University, where he investigated how the gut microbiota regulates host immunity to Mycobacterium tuberculosis. His current research focuses on uncovering causal relationships between the early-life gut microbiota of infants exposed to HIV and uninfected (iHEU) and their systemic and mucosal immune responses. He is also studying the impact of maternal antiretroviral therapy on the gut microbiota and immunity in mothers and their offspring.

Oscar Pellon-Cardenas, PhD

Research Teaching Specialist

Oscar earned his PhD in Molecular and Cell Biology from the University of Notre Dame, where he investigated the mechanisms regulating canonical Wnt/β-catenin signaling in epithelial cells. He then completed a postdoctoral fellowship with Dr. Michael Verzi, where he studied how transcriptional and signaling networks, particularly involving CDX2, β-catenin, and BRAF govern tumor initiation and intestinal epithelial transformation using mouse genetics, organoids, and single-cell approaches. As a founding member of the Nyangahu Lab, Oscar helps ensure the smooth operation of the lab and supports protocol development and training of new members.

 

Donald Nyangahu, PhD

Assistant Professor

Donald completed his PhD in Immunology from the University of Cape Town where he studied the impact of maternal microbiota or infections during pregnancy or nursing on offspring immunity. He moved to University of Washington and Seattle Children’s Research Institute where he did his postdoctoral fellowship investigating the relationship between early life gut microbiota in infants exposed to HIV but uninfected (iHEU) and BCG vaccine response. Donald joined the faculty at CABM in September 2024, where his lab continues to investigate the contribution of early life gut microbiota of iHEU to clinical outcomes.
