Dr. Wendy J. Dahl


Dr. Dahl’s current research interests focus on examining the role of fiber and prebiotics in medical nutrition therapy, specifically the role of isolated fibers on various outcomes of chronic kidney disease. She collaborates extensively on studies related to effects of fiber, prebiotics and probiotics on overall health and wellness, gastrointestinal health, immunity and their relationship to gut microbiota. Dr. Dahl is also actively involved in the scholarship of teaching and learning, exploring ways to improve the undergraduate student’s learning experiences.
