Defended on 11th December 2006, Orsay.

I work in the School of Mathematics and Statistics at UCD. Come visit!

My research career has been supported by the French government, the Marie Curie network CODY, the Wallenberg Foundation, the Gustafsson Foundation, an IBM Herman Goldstine Fellowship, the Academy of Finland and the ERC.

I organise the UCD Junior Maths Enrichment activities.
