Symposium Speakers


Dr. Mazdak Arabi

Professor & Director

Colorado State University & One Water Solutions Institute

Dr. Mazdak Arabi is the director and founder of the One Water Solutions Institute at Colorado State University. His research is primarily focused on development of decision support systems for management of water resources at the watershed scale. To make informed decisions, policy makers should have the tools necessary to identify areas that are most vulnerable to erosion and contaminant transport, and subsequently assess tradeoffs between environmental and economic impacts of management actions. Dr. Arabi has developed and demonstrated optimization-based approaches to facilitate development of watershed management plans that achieve water quality goals at significantly lower costs. He has published analytical and computational methods to support both deterministic and probabilistic evaluation of watershed-scale benefits of best management practices

Daniel Bowker

Forest & Fire Project Manager

Coalition of the Poudre River Watershed

A born-and-raised Kentuckian, Daniel came of age thinking deeply about the changes he saw as his home state transformed from small family farms to the urban-rural hybrid it is today. After finishing degrees in philosophy, he followed his calling out of doors, returning to the University of Kentucky to complete a Bachelor of Science in forestry. Following graduation, UK hired Daniel as a forester on the university’s 15,000 acre Robinson Forest, in the rugged Cumberland Plateau region of eastern Kentucky. While there, Daniel spearheaded research into local commercial logging practices, testing the effects of the state’s streamside management zone regulations on water quality and riparian biota, and received his Master of Science in forestry along the way. Daniel moved to Fort Collins in 2010, and worked with the US Forest Service Rocky Mountain Research Station on the mountain pine beetle outbreak in northern Colorado. He then spent several years with the Natural Resource Ecology Lab at Colorado State University, managing a long-term research program in the Loch Vale watershed of Rocky Mountain National Park. Most recently, Daniel served as a forester with the conservation districts in Boulder County, delivering Farm Bill assistance to private landowners working to thin and restore their forests for wildfire resilience and forest health.
