Sean O’Neil is a doctoral candidate in the Department of History and the Institute for Comparative Literature and Society at Columbia University, where he studies the history of science in early modern Europe. His dissertation examines how the credibility of symbolic notations (e.g. algebraic symbolism, chemical formulae, stenography, etc.) was established during the Scientific Revolution, often despite trenchant critiques of their limitations. Prior to coming to Columbia, Sean earned bachelor’s degrees in linguistics and English literature at Truman State University in Missouri and a master's degree in folklore at the University of California, Berkeley. He also worked for five years as a high school instructor, teaching in the United States and Japan.
