## Field Description

The graduate program in the field of mathematics at Cornell leads to the Ph.D. degree, which takes most students six years of graduate study to complete. One feature that makes the program at Cornell particularly attractive is the broad range of interests of the faculty. The department has outstanding groups in the areas of algebra, algebraic geometry, analysis, applied mathematics, combinatorics, dynamical systems, geometry, logic, Lie groups, number theory, probability, and topology. The field also maintains close ties with distinguished graduate programs in the fields of applied mathematics, computer science, operations research, and statistics and data science.

**Application:**

Applicants must demonstrate mastery of the material required for an undergraduate major in mathematics. The mathematics field welcomes applications from and admits students with various mathematics backgrounds. GRE General and Subject Test scores are not required and will not be considered. Detailed academic requirements can be located in the graduate field handbook. Applicants must meet the minimum Graduate School Requirements, including the English Language Proficiency Requirement for all applicants

**Campus:**Ithaca**Concentrations:***Mathematics:*mathematics**Research Interests:**Number theory, arithmetic geometry My research is in number theory and more specifically in arithmetic geometry. I like to study the family of compatible Galois representations associated to various arithmetic objects (eg. abelian varieties, modular forms, Drinfeld modules); these representations encode much, if not all, of the arithmetic of the originally object. Galois representations can also be used to study the absolute the Galois group of the rational numbers, and I have recently been playing with some applications to the Inverse Galois Problem.
