Dr Groussin will discuss how the Global Microbiome Conservancy is working to address gaps in microbiome research by collecting, culturing, and sequencing microbial communities from a large global cohort of human populations that have highly differentiated genetic backgrounds, diets, and lifestyles. He will highlight how this effort contributes to a more inclusive and accurate picture of microbial diversity, evolution, and function. In parallel, he will introduce his ERC-funded research on the gut vesiculome (the vast array of extracellular vesicles produced by bacteria that enable inter-microbial communication and influence host physiology). Together, these projects shed light on how bacterial communities adapt, share genes, and interact with their environment, offering new opportunities for understanding microbial evolution and developing microbiome-based therapies.


Associate Professor, University of San Francisco
Dr Naupaka Zimmerman is an Associate Professor of Biology and Director of the MS Biology Program at the University of San Francisco. His research explores microbial ecology, with a focus on the communities of fungi that live inside plant leaves without causing disease, known as endophytes. His work investigates how environmental conditions, host species, and geography influence the diversity and function of these microbes.
Born and raised on the Big Island of Hawaiʻi, Dr Zimmerman has studied the microbial ecology of native Hawaiian plants, particularly Metrosideros polymorpha. At USF, his lab also works on plant–microbe interactions in urban environments and sustainable farms, including research across San Francisco and at Star Route Farms in Marin County. His team uses fieldwork, microscopy, DNA sequencing, and bioinformatics to understand how plant-associated microbes contribute to ecosystem processes such as decomposition, plant health, and resilience to pathogens.
