This is Martin Bright's mathematical home page.

I am a member of the Mathematisch Instituut at the University of Leiden in the Netherlands. I work in the area of Diophantine equations and arithmetic geometry, specifically on the Brauer–Manin obstruction and related questions about rational points on varieties.

In 2020–21 I am teaching Lineaire Algebra 1, the Mastermath course Advanced Algebraic Geometry: Rational Points (with Ronald van Luijk) and Algebra 1 (with Federica Pasquotto).

Lecture notes: Descent by 2-isogeny (following Cassels). (Corrections welcome!)

Here is a list of my publications and preprints, together with slides from some talks.

Notes from the Autumn School in Mainz, October 2017 are available here.
