  • Gregg Treinish

    Global Perspectives Guest Speaker

    With a strong passion for both scientific discovery and exploration, Gregg founded Adventurers and Scientists for Conservation in 2011, a nonprofit organization connecting outdoor adventurers with scientists in need of data from the field. The ASC’s goal is to build a bridge between the scientific and outdoor communities. Adventure athletes contact the organization and volunteer to collect data on their travels. ASC matches them with researchers who need help getting expensive, time-consuming, hard-to-reach information. More than a hundred scientific organizations and a thousand adventurers have already participated. Gregg also organizes his own expeditions, contributing to research on wildlife-human interaction, fragmented habitats, and threatened species.
