Alexandra Witze is a contributing correspondent based in Boulder, Colorado. Among other exotic locales, her reporting has taken her to Maya ruins in the jungles of Guatemala, among rotting corpses at the University of Tennessee's legendary "Body Farm," and to a floating sea-ice camp at the North Pole. She has a bachelor's degree in geology from MIT and a graduate certification in science communication from the University of California, Santa Cruz. Among her honors are the Science-in-Society award from the National Association of Science Writers (shared with Tom Siegfried), and the American Geophysical Union's award for feature journalism. She coauthored the book Island on Fire, about the 18th-century eruption of the Icelandic volcano Laki.
