Katrina Waters

Dr. Waters represents a group of scientists at the Pacific Northwest National Laboratory. They are captivated by the aesthetic structures of bacteria encountered as they work to develop a model of the microbial environment inside the human gut. This model is composed of three-dimensional human intestinal cells cultured with specific gut bacteria. Changes in certain bacterial populations within the gut have been attributed to colon cancer, obesity, type 2 diabetes, and neurological diseases such as Alzheimer’s and Huntington’s diseases. The three-dimensional model provides an approach to study how changes in bacteria affect gut health and overall human health. Research was funded by the U.S. Department of Health and Human Services and PNNL’s Laboratory Directed Research and Development initiative in chemical imaging.
