My name is Jonny Evans. I'm a senior lecturer in mathematics at University College London (UCL), part of the UCL Geometry and Topology Group.

Teaching

In 2014, I produced a visual guide to the UCL undergraduate mathematics course and here is the source code I used.

2015-2016

Previous teaching


Research

I am interested in symplectic topology and Floer theory, particularly in questions about Lagrangian submanifolds.

Me on arXiv and MathSciNet.

My collaborators: Jarek Kędra, Yankı Lekili, Georgios Dimitroglou Rizell and Ivan Smith.
