Under his leadership, Voiijer is on track to become the largest repository of user-generated environmental content and data, ultimately reconnecting people with the planet, advancing science through shared observation, and inspiring new generations of explorers.
Michael’s work spans continents, combining far-flung scientific expeditions with global initiatives. Earlier in his career, he spearheaded the development of Bhutan’s first law school and launched GNH Partners, the country’s first impact fund. He also founded “upublic” at Columbia University to advance global education and technology initiatives, and helped design the U.S. Department of Education’s first national online learning portal for adult education. A Fellow of both the Royal Geographical Society and The Explorers Club, Michael also founded The Explorers Club Hong Kong Chapter.
We are thrilled that he is joining our panel of scientific advisors and our Executive Director, CanopyMeg Lowman, is the Chair of his Scientific Board, so the cross-pollination of science, adventure and purpose will be a mutual benefit.
