Professor Keck’s teaching focuses on law and politics, mostly though not exclusively in the United States. He regularly teaches a two-semester sequence in constitutional law (PSC 324 and PSC 325), as well as a stand-alone course on free speech (PSC 300). The con law sequence examines the major constitutional conflicts that have shaped American political development from the framing of the Constitution in 1787 up through the most recent decisions of the Roberts Court. At the graduate level, he explores similar ground in a seminar on American constitutional development (PSC 711), which is generally offered every other Spring.
