Welcome!

I am a lecturer in pure mathematics at the University of St Andrews. My research is in algebraic and tropical geometry. See my research page for more detail.

Here is my CV (updated October 2021).

My email address is yoav.len@st-andrews.ac.uk.

Recent and upcoming maths travel: I do most of my maths in a socially distant fashion these days.

I strongly believe in the axioms laid out by Federico Ardila:

Axiom 1. Mathematical potential is distributed equally among different groups, irrespective of geographic, demographic, and economic boundaries.

Axiom 2. Everyone can have joyful, meaningful, and empowering mathematical experiences.

Axiom 3. Mathematics is a powerful, malleable tool that can be shaped and used differently by various communities to serve their needs.

Axiom 4. Every student deserves to be treated with dignity and respect.
