## Dr Kirsti Biggs

I am currently a Heilbronn Research Fellow at the University of Bristol, working in Analytic Number Theory.
From January 2020, I will be a postdoc at 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, also at the University of Bristol, working under the supervision of Professor Trevor Wooley.
