John E. Baatz

John E. Baatz, PhD, serves as a Professor in the Department of Pediatrics at the Medical University of South Carolina's College of Medicine. His academic focus centers on neonatal lung development, oxygen homeostasis in lung disease, and innovative lung cryopreservation techniques, driving significant translational research in pulmonary biology and neonatal health.

Dr. Baatz's educational foundation includes:

• B.S. in Chemistry from the University of Cincinnati (1983)
• Ph.D. in Biochemistry from the University of Cincinnati (1988)
• Postdoctoral Fellowship at Children’s Hospital Medical Center, Cincinnati (1990)

His laboratory pioneers three interconnected research domains: structural analysis of lipid-associated proteins (including lung surfactant and human milk components), oxygen-sensing mechanisms in alveolar epithelial cells, and bioengineered scaffolds for lung tissue regeneration. A landmark achievement is his human tissue cryopreservation method preserving viability for over six years, enabling critical discoveries about lactate metabolism defects in idiopathic pulmonary fibrosis. This technique supports batch experiments across multiple tissue types including lung, bone, and placenta.

Recent publications (2014-2022) reveal strong interdisciplinary trends bridging neonatology, biochemistry, and tissue engineering. Key themes include human milk cytotoxicity mechanisms in preterm infants, maternal vitamin D's immunological impact on breastfeeding infants, and metabolic adaptations in lung cells under hypoxia. His work consistently integrates proteomics, lipid biochemistry, and cryopreservation to address fundamental questions in lung development and disease.

Dr. Baatz maintains highly collaborative research relationships, particularly with Drs. Carol Wagner and Katie Chetta on human milk composition and newborn gut maturation. His laboratory provides specialized expertise in proteomics and lipid analysis, advancing understanding of how milk components influence infant health outcomes. The cryopreservation protocol developed by his team represents a critical methodological advancement enabling longitudinal studies of primary human tissues.

The Baatz laboratory operates at the intersection of pulmonary biology and neonatal medicine, with physical infrastructure supporting advanced cell culture, cryopreservation, and metabolic analysis. Current work focuses on applying the cryopreservation technique to identify therapeutic targets for idiopathic pulmonary fibrosis while expanding applications to other tissue systems. The lab's collaborative framework with clinical researchers demonstrates strong translational potential for improving neonatal and pediatric respiratory outcomes.
