Glenda Eoyang, PhD, works with public and private organizations to help them thrive in the face of overwhelming complexity and uncertainty. She is a pioneer in the field of human systems dynamics (HSD), which she founded.

Her clients include Centers for Disease Control and Prevention, Oxfam International, Canada School of Public Service, Cargill, Fraser Health Authority (BC), and Roche/Genentech. Dr. Eoyang's latest book, with co-author Royce Holladay, is Adaptive Action: Leveraging Uncertainty in Your Organization (Stanford University Press, April 2013).
