Dr. Weiss' research focuses on epidemiology of pediatric sepsis and mitochondrial dysfunction in sepsis-associated organ injury. The driving hypothesis for his NIH-funded research is that alterations in mitochondrial bioenergetics contribute to organ injury and immune dysregulation in a subset of children with sepsis.

He has several active studies evaluating risk factors, biomarkers, and mechanisms of organ dysfunction in pediatric sepsis, including changes in the intestinal microbiome.

The long-term goal of Dr. Weiss' translational research program is to identify a targeted therapeutic approach to augment mitochondrial bioenergetics and improve clinical outcomes for children with sepsis-associated immune dysregulation and organ injury.
