**Graduate study at UW-Madison in algebra**

Algebra is among the most popular specializations for UW Ph.D. students. Regularly offered courses include a four-semester sequence in number theory; a two-semester sequence in algebraic geometry; homological algebra; representation theory; advanced topics in group theory. We also regularly offer more advanced topics courses, which in recent years have included the Gross-Zagier formula, classification of algebraic surfaces, and p-adic Hodge theory.

Recent Ph.D. graduates from the group have been very successful on the job market; in the last few years, we have sent alumni to postdoctoral fellowships at Berkeley, Harvard, Chicago, Michigan, Penn, Imperial (UK), MIT, Princeton, Stanford, University of Cologne(Germany), Max Planck Institut, and UT-Austin, to tenure-track jobs at Georgia, Washington U., UIUC, Dartmouth, Bowdoin, Leiden, Oregon, Wake Forest, Bogacizi (Turkey), Chennai Mathematical Institute (India), Reed College, Portland State U., the University of Sheffield (UK), the University of Missouri, and the University of South Carolina, and to non-academic positions at places such as Google, Two Sigma, Robart GMBH, Microsoft, Credit Suisse and the Center for Communications Research, La Jolla.
