Mary Ellen Hannibal is an author and avid citizen scientist from the Bay Area. Her work focuses on science, culture, and the important connections between people, species and eco systems. Her most recent book, Citizen Scientist: Searching for Heroes and Hope in an Age of Extinction, was named one of the best titles of 2016 by the San Francisco Chronicle. Reporting deeply, Hannibal digs into the origins of today’s tech-savvy citizen science movement — tracing it back through centuries of amateur observations by writers and naturalists. Prompted by her novelist father’s sudden death, she connects the activity of bearing witness to nature today with a broad inquiry into time, place and purpose. Hannibal’s previous books include The Spine of the Continent, about which Publisher’s Weekly said, “This is what science writing should be: fascinating and true.” Her work has appeared in The New York Times, Esquire, Nautilus and many other publications. She is a frequent speaker and emissary bringing science to a general audience.
