Research Interests

My work is broadly classified as homotopy theory, and I'm particularly interested in its interactions with algebraic geometry and algebra. Much of my work has involved algebraic K-theory and higher categories.

Biographical Statement

Clark became interested in mathematics as a youngster in North Carolina, where he would remain to receive his 2001 B.S. His 2005 Ph.D from the University of Pennsylvania preceded a string of postdoctoral positions – Göttingen, Oslo, the Institute for Advanced Study, and finally Harvard. Clark joined the faculty at the Massachusetts Institute of Technology in 2010 as Assistant Professor; in 2015 he was promoted to Associate Professor. But during his time as Fulbright Visiting Professor at the University of Glasgow, Clark and his partner Alexandra became smitten with Scotland, and now they merrily return as he takes up a post as Reader in Mathematics at the University of Edinburgh.
