Daniel is the author of field guides to Edible Mushrooms of the Pacific Northwest and California (both Harbour Publishing, 2011 and 2012), Amazon Mushrooms (2014, co-authored) and a brand new "Field guide to Medicinal Mushrooms of North America with Robert Rogers". He grew up collecting and eating wild mushrooms in the Alps and has been foraging for over 20 years in the Pacific Northwest and beyond, sharing his enthusiasm as a mushroom educator, guide, and as Puget Sound Mycological Society vice-president. In his presentations he is combining his stunning photography with an often funny blend of entertaining stories and scientific information, which he likes to refer to as "edutainment". Having been in love with mushrooms since early childhood, Daniel managed to bend his career as an ecologist and geographer focused on High Asia towards researching mushrooms and rural income in Tibet. His Cordyceps research has been featured in The Economist, National Geographic, New York Times, Wall Street Journal, NPR, and BBC. In the last decade, Daniel started exploring neotropical fungi. With his travel agency MushRoaming, Daniel is organizing mushroom focused eco-tours to Tibet, Bhutan, the Amazon, Colombia, the Alps and mushroom events in the Pacific Northwest since 2007.
