Associate Researcher at the GAATI Laboratory, Université de la Polynésie française.
Office: Innovation E439.

This fall I am teaching Abstract Algebra I and Fundamentals of Mathematics.

Before UVM I was a postdoc of Ehud Hrushovski, and a student of Alexandru Buium. My work tends to revolve around Diophantine equations, differential algebraic geometry, deformation theory, Witt vectors and the Frobenius, absolute geometry, applied model theory, and abelian varieties. I'm happy to talk to anyone about any kind of math; send me an email.

Seminars

• QVNTS — Quebec-Vermont Number Theory Seminar, biweekly at McGill and Concordia.
• unQVNTS — the local arithmetic geometry seminar, on QVNTS off weeks.
• GAATI Séminaire — arithmetic geometry seminar at the GAATI Laboratory, Université de la Polynésie française (co-organized 2025–2026).
• Algebraic Geometry Learning Seminar (not active).

For students

• Asking for a letter of recommendation?
• On studying arithmetic geometry: Emerton's comment on Terry Tao's blog.

Past conferences I've organized

• Arithmetic Geometry, AMS Western Sectional, Albuquerque, 2021.
• Witt Vectors, Deformations and Absolute Geometry, Burlington, Summer 2018.
• Super QVNTS workshop on Anabelian Geometry and Kummer Classes, Burlington, Fall 2016.
• Special Session on Differential and Functional Equations, JMM, Atlanta, 2016.
