Katie Amato is a biological anthropologist studying the gut microbiota in the broad context of host ecology and evolution. She is particularly interested in understanding how changes in the gut microbiota impact human nutrition and health in populations around the world, especially those with limited access to nutritional resources. She also uses non-human primates as models for studying host-gut microbe interactions in selective environments and to determine whether the human gut microbiota has characteristics that are unique among primates. Her current research focuses on microbial contributions to host nutrition during periods of reduced food availability or increased nutritional demands, as well as microbial influences on brain growth. She has worked in the field extensively with black howler monkeys in southeastern Mexico, and is currently establishing projects with both humans and non-human primates in other parts of the world.

Dr. Amato’s work has been supported by grants from the National Science Foundation and the National Geographic Society. She was recently invited to speak at TEDx Jackson Hole as well as the Early Career Scientists Symposium at the University of Michigan.
