Postdoctoral Research Associate - Pediatrics Cardiology

About the role

Location

Position Summary

The Woo Lab within the Division of Cardiology and Department of Pediatrics at WashU Medicine in St. Louis is recruiting a Postdoctoral Research Associate to investigate the mechanisms of Group 3 hypoxia-induced pulmonary hypertension and develop strategies to prevent or reverse pulmonary vascular remodeling.

We study how chronic hypoxia disrupts vascular homeostasis and reprograms endothelial cells, smooth muscle cells, pericytes, and fibroblasts, leading to elevated pulmonary pressures and right ventricular dysfunction. By integrating mechanistic studies in genetic mouse models and patient-derived human samples with single-cell genomics and preclinical therapeutic testing, we aim to identify conserved, actionable disease pathways.

Current Research Directions

• Define the molecular mechanisms that regulate pulmonary vascular smooth muscle cell and pericyte plasticity, differentiation, and maladaptive remodeling.
• Investigate endothelial dysfunction and endothelial-to-mesenchymal transition during chronic hypoxia and pulmonary vascular disease.
• Determine how FGF and other growth-factor signaling pathways control vascular cell identity, inflammation, and intercellular communication.
• Apply single-cell RNA sequencing, single-nucleus multiomics, spatial transcriptomics, and computational analysis to identify disease-associated vascular cell states.
• Validate candidate pathways using mouse genetics, human vascular cells, induced pluripotent stem cell-derived models, and clinically relevant human samples.
• Develop targeted nanoparticle platforms and mechanism-based therapeuticstrategies to prevent or reverse pulmonary vascular remodeling and treat pulmonary hypertension.

Role and Mentorship

The postdoctoral researcher will lead a mechanistically focused project and have substantial opportunity to shape its scientific direction, establish new experimental or computational approaches, build interdisciplinary collaborations, and develop an independent research niche. Individualized mentorship will support rigorous study design, scientific communication, fellowship development, leadership, and career advancement.

Research Environment

WashU Medicine provides state-of-the-art core facilities, human translational research resources, and a broad collaborative community spanning cardiovascular and pulmonary medicine, pediatrics, genomics, pathology, and bioengineering.
