Karthikeyani Chellappa PhD

Principal Investigator

Department of Molecular Microbiology and Immunology

Center on the Biology of Aging

Karthi started her lab at Brown University in May 2023. Karthi is a hard-core metabolism enthusiast. Karthi is leading her team to tackle the biology of aging from the perspective of the host and host-microbiome interactions using an array of interdisciplinary approaches with a goal of identifying interventions to promote healthy aging. She is also passionate about inter-organ communications and systemic metabolism. She looks forward to connecting with researchers near and far. In her free time, Karthi loves to read, scout out new restaurants, and relax with friends and family.
