Glenn J. Rapsinski, MD, PhD

  • Assistant Professor of Pediatrics

Dr. Rapsinski received his bachelors of science degree in biology from Saint Vincent College for his undergraduate education. He then attended the Lewis Katz School of Medicine at Temple University where he completed the MD/PhD program and was inducted into Alpha Omega Alpha Honors Society. His PhD research examined the development of and immune responses to the amyloid component, curli fibrils, of biofilms formed by Salmonella typhimurium. He completed his pediatrics residency and pediatric infectious diseases fellowship at UPMC Children's Hospital of Pittsburgh. During fellowship, he studied respiratory tract infections in patients with cystic fibrosis including the sinus microbiome during chronic rhinosinusitis and Pseudomonas aeruginosa responses to host potassium improving biofilm formation on airway epithelium in the lab of Dr. Jennifer Bomberger.

As an independent researcher, Dr. Rapsinski's Lab focuses on chronic bacterial Pseudomonas aeruginosa in children who require mechanical ventilation.  The lab uses clinical isolates to examine adaptations of P. aeruginosa to the airway environment when a child needs mechanical ventilation.  We also use vitro evolution models to understand the contributions of the abiotic surface and the nutritional environment to these adaptations.  Lastly, the lab studies host pathogen interactions at the airway epithelial cell interface using air-liquid interface models with primary airway epithelial cells and changes in the host epithelium resulting from prolonged ventilator support.  

His clinical research interest is improving patient care through diagnostic stewardship and studying the management of infections in children with chronic ventilator needs.
