Sophia Roosth is the Frederick S. Danziger Associate Professor in the Department of the History of Science at Harvard University. Roosth was the 2016 Anna-Maria Kellen Fellow of the American Academy in Berlin. In her book Synthetic: How Life Got Made (2017), Roosth asks what happens to “life” as a conceptual category when experimentation and fabrication converge. Grounded in an ethnographic study of synthetic biologists, she documents the profound shifts biology has undergone in the post-genomic age. Her forthcoming book, The Quick and the Dead, will offer a historically and ethnographically informed travelogue into the worlds of contemporary geobiologists, scientists seeking ancient microbial life-forms fossilized in stone.
