Henry Bradford

I am a Fellow and College Teaching Officer at Christ’s College Cambridge, and a member of the University of Cambridge’s Department of Pure Mathematics and Mathematical Statistics.

My area of research is asymptotic group theory. I am interested in a range of questions concerning constructions of expander graphs; diameters of Cayley graphs; word maps on groups and random walks. I am also increasingly interested in properties of infinite groups which allow one to approximate them by finite groups, including residual finiteness; local embeddability and soficity.

From 2016 to 2019 I was a postdoctoral research assistant at the University of Göttingen, where I worked in the research group of of Prof. Harald Andrés Helfgott. I completed my DPhil at the University of Oxford in 2015, under the supervision of Prof. Marc Lackenby.

Outside mathematics I am a music-lover; a jogger, and a collector of postcards.

Teaching

In Lent Term 2022 I shall be lecturing Part III Infinite Groups. Supporting materials, including lecture notes and example sheets, shall appear here in the fullness of time. In the meanwhile, see here for some introductory notes covering material which will be prerequisite for the course.
