Biography and Research Information

OverviewAI-generated summary

Clark Sims studies the relationship between maternal health, particularly overweight and obesity, and infant development. His research investigates how factors such as maternal diet, body composition, and human milk composition influence infant growth, gut microbiome, and skeletal development. Sims has received funding for projects examining the associations between maternal obesity and offspring gut microbiome in the first year of life, and the impact of maternal diet and body composition on gut microbial ecology during pregnancy. His work also explores the effects of human milk oligosaccharides and branched-chain amino acids on infant growth, and how breastfeeding duration modifies the association between maternal weight status and offspring dietary palmitate oxidation. Sims has also investigated the association between per- and polyfluoroalkyl substances (PFAS) during pregnancy and maternal cardiometabolic outcomes.
