Liz Johnson

Liz Johnson is an Assistant Professor in the Division of Nutritional Sciences at Cornell University, part of the College of Human Ecology. Her research focuses on sphingolipid-dependent host-microbe interactions, infant nutrition, and microbiome dynamics. She employs advanced techniques such as high-throughput sequencing and lipidomics to study how microbial sphingolipids influence host metabolism, insulin signaling, and disease prevention. Her work also explores the role of sphingolipids in human milk and their impact on infant gut microbiome development.

Research Interests:

• Host-microbe signaling pathways
• Sphingolipid metabolism in health and disease
• Infant nutritional programming
• Microbiome-liver axis interactions

Recent studies highlight her lab’s exploration of microbiome-driven mechanisms in metabolic disorders and skin health. Collaborative projects with institutions studying lipid metabolism and aquaculture nutrition further extend her research portfolio.
