Karthikeyani Chellappa (Karthi) is an Assistant Professor in the Department of Molecular Microbiology and Immunology at Brown University, as well as a member of the Center on the Biology of Aging. Her research is focused on understanding the critical role of metabolism in driving complex phenotypes related to aging through innovative, integrative approaches. The Chellappa Lab aims to explore how metabolic processes influence the behavior and interactions of host organisms with their microbial communities. Karthi joined Brown University in 2023 after completing her PhD at the University of California, Riverside, and conducting postdoctoral work at the University of Pennsylvania. Her work involves dissecting the metabolic basis of aging and investigating how alterations in metabolism affect resilience to environmental stressors. This research also seeks to uncover the implications of microbiome composition on host physiology and metabolic diseases. Karthi's work is characterized by utilizing advanced techniques such as stable-isotope tracing and gnotobiotic mouse models to study the interconnections between metabolism and microbial interactions.
