John Voight is professor of mathematics at Dartmouth College. He received his Ph.D. in 2005 from the University of California, Berkeley, and has held positions at the University of Sydney, the Institute for Mathematics and its Applications (IMA) at the University of Minnesota, and the University of Vermont. Voight’s research interests are in arithmetic geometry and number theory, with a focus on algorithmic aspects. His current research concerns computational problems for moduli spaces and automorphic forms. He is the author of a textbook on quaternion algebras and received an NSF CAREER award. He was the recipient of the Selfridge Prize in 2010 and currently serves on the board for the L-functions and Modular Forms DataBase (LMFDB).
