Regular biography
Sallie (Penny) W. Chisholm is an Institute Professor at the Massachusetts Institute of Technology, affiliated with the Department of Biology. Her research focuses on the biology, ecology, and evolution of the most abundant marine phytoplankton species, with a particular emphasis on the cyanobacterium Prochlorococcus. She investigates how these microbes influence global biogeochemical cycles and the forces shaping microbial ecosystems. Chisholm's work spans from genomic to ecosystem-level studies, using Prochlorococcus as a model system. She is also recognized for her contributions to understanding the structure and function of microbial diversity in marine environments.
Scholar-generated biography
Sallie W Chisholm is an Institute Professor at the Massachusetts Institute of Technology, specializing in Oceanography, Microbiology, and Ecology. Her research focuses on marine microbial communities, particularly the ecological roles of Prochlorococcus and Synechococcus, and their interactions with environmental factors such as light, temperature, and nutrient availability. She investigates microbial gene expression, niche differentiation, and the impact of viral infections on marine cyanobacteria. Her work explores the biogeography and physiology of microbial populations in oceanic ecosystems, contributing to understanding the global carbon cycle and microbial diversity in the ocean's interior.
