Dr Kirsti Biggs

Kirsti Biggs

I am currently a postdoctoral researcher in analytic number theory at the Chalmers University of Technology / University of Gothenburg, working with Dr Julia Brandes.
My research involves the Hardy–Littlewood circle method and its application to Diophantine problems, particularly various analogues of Waring's problem. I am also interested in Diophantine approximation and additive combinatorics.

Prior to this, I was a PhD student at the University of Bristol, working under the supervision of Professor Trevor Wooley.
