Max Holmes is motivated by a vision of science that connects people with each other and the natural world to make a positive impact on society. This is reflected in the collaborative, community-based river research programs he has created. Most recently, Science on the Fly, which is an initiative that unites the fly-fishing and science communities to study and protect rivers around the world. His research spans the globe–from the Siberian Arctic to the tropical Amazon–and focuses on how climate change and other disturbances impact water and chemical cycles in the environment. He is also interested in the vast quantities of ancient carbon held in Arctic permafrost, which may be released as permafrost thaws, exacerbating global warming. With ongoing projects in the Russian, Canadian and Alaskan arctic, as well as in the Congo and the Amazon, Holmes earned the honorable title of National Fellow of the Explorers Club in 2015.
