Picture of me
I am a Researcher at the Department of Mathematics at KTH, the Royal Institute of Technology, supported by a junior researcher grant from the Swedish Science Council. Prior to this I was a Gustafsson postdoctoral research fellow in Pär Kurlberg's number theory group at KTH, and prior to coming to KTH I was an EPSRC postdoctoral research fellow at Queen Mary, University of London. I did my PhD under the supervision of Ben Green at some blend of the University of Bristol, MIT and the University of Cambridge. My research has mainly been in an area of mathematics called additive combinatorics, a subject touching on combinatorics, analysis, probability and number theory. I am particularly interested in using ideas from analysis and probability to tackle problems of a combinatorial or number theoretical nature.

Current research
I am interested in many questions in additive combinatorics and number theory. My main research topics are: Roth's theorem and its extensions; applications of analytic ideas to combinatorial problems; higher-order Fourier analysis; extremal structures in additive combinatorics and the structure of structure-avoiding sets; computational aspects of additive number theory. I am particularly interested in ways in which one can isolate the important aspects of some data and represent these using a small number of parameters.
