I did my undergraduate and masters degree in Mathematics at Cambridge, where I remained to do my PhD in the Statistical Laboratory under the supervision of James Norris. I then spent a year working as a postdoc in the Laboratoire de Probabilités et Modèles Aléatoires at Université Paris VI with Jean Bertoin. From 2004 to 2007, I was the Stokes Fellow in Mathematics at Pembroke College, Cambridge. From 2007 to 2009, I held an EPSRC Postdoctoral Fellowship in the Department of Statistics at Oxford and a Junior Research Fellowship at Wolfson College. From 2009-2011, I was an Assistant Professor in the Department of Statistics at Warwick, before returning to Oxford to take up my present position. From January 2016 to December 2020 I held an EPSRC Early Career Fellowship. I was awarded the title of Professor of Probability in 2017.
