Antoine Goldsborough
I am an LMS Early Career Fellow working with Radhika Gupta at the Tata Institute for Fundamental Research in Mumbai.
In April 2024, I completed my PhD at Heriot-Watt University under the supervision of Alessandro Sisto. Previously, I graduated with a Master's at the University of Paris and a MMath degree at the University of St Andrews.
My main research interest is geometric group theory. I am especially interested in random walks on groups and how they interact with quasi-isometries, as well as generalisations of hyperbolic groups and spaces.
