Dr Shaun Hotchkiss

Profile Image
Research Fellow


I grew up in Auckland and was an undergraduate here from 2002-2006. Before arriving back I was a postdoctoral researcher in Brighton at Sussex University from 2013-2015, and before that I was at the Helsinki Institute of Physics and University of Helsinki from 2010-2013.

Before that, I received my doctorate from the theoretical physics department at Oxford University. While in Oxford, I was a post-graduate student at Balliol College. Before that, I was an undergraduate student of physics and maths here at the University of Auckland.


I also contribute to a collaborative blog, The Trenches of Discovery. The purpose of the blog is to help make fundamental research more accessible, as well as to open up a dialogue between different fields of research. More details regarding our motivation can be found here and here. And I also help to run the Life Beyond School programme.
