Biodesign Center for Health Through Microbiomes

Microbial universe within can improve health

Microbes that live in our bodies affect our health in positive or negative ways. They produce vitamins, help us digest food, train our immune system, produce and consume neurotransmitters and protect us against pathogens. When thrown off balance from our industrialized lifestyle, poor diet and over-use of antibiotics, our health can suffer, too. This unbalance triggers problems such as obesity, type 2 diabetes, altered metabolism, autism, depression, Clostridium difficile infections, irritable bowel syndrome, colon cancer and altered drug metabolism. Increased understanding of the human microbiome and possible interventions will enable us to prevent or fix microbial imbalances.

Our team creates fundamental knowledge to develop microbe-based health interventions and diagnostics for better human health. Using fundamental knowledge of microbiomes, we develop methods to identify and track gut microbes and their products and develop microbial interventions for better human health.



Rosa Krajmalnik-Brown, PhD


Rosa Krajmalnik-Brown is an expert in using microorganisms to solve problems in human health and the environment. She is leading research into the connection between gut bacteria and the conditions of autism and obesity/metabolism. Other areas of interest include bioremediation of soil, sediments and groundwater and the use of microbial systems to produce energy.
