In 1993 I graduated with a first class honours Bachelor of Arts in Mathematics from the University of Oxford, where I studied at St. Anne's College. In 1996 I graduated from the School of Mathematics and Statitics, Sheffield University with Ph.D. in Probability Theory under the supervision of John Biggins. I then worked for six months at the Department of Statistics in the London School of Economics as a temporary lecturer. In 1997, I moved to The Netherlands where I worked for nearly two years for Shell International Exploration and Production as a mathematician in their Rijswijk research laboratories. I returned to academia at the end of 1998, where I took up a temporary lectureship at the School of Mathematics, Edinburgh University. There, I ran one of the UK's first MSc programmes in Mathematical Finance. At the turn of the Millennium, I moved back to The Netherlands where I worked at the Mathematical Institute at Utrecht Univeristy as a "Mathematics in Focus" research fellow with the tile of univeristeit docent (assistant professor). I spent over five very happy years there, during which time I obtained tenure. In mid 2005, I moved back to the UK. Initially I took a readership at The School of Mathematical and Computer Science, Heriot Watt in Edinburgh, but after a year, in 2006, I moved to a readership at in my current department at the University of Bath. In 2008, I became a full professor, around which time, together with colleagues, I began working on building the Probability Laboratory at Bath (Prob-L@B) and continue to do so today. For two months in 2010 I was visiting professor at the Mathematics Department, Université Libre de Bruxelles and between August 2012 and February 2013, I was visiting professor at the Institute for Mathematical Research, ETH Zürich. Since 2014 I hold a visiting professorship at CIMAT, Mexico, where I visit, on average, every 3-6 months. In 2014, following the award of a multi million pound grant from EPSRC, on which I serve as PI, I became co-director of the EPSRC Centre for Doctoral Training in Statistical Applied Mathematics (SAMBa). In 2015, together with numerous colleagues, I began working on the Bath-UNAM-CIMAT (BUC) research platform. Since 2015, I have also been working with a broad range of mathematicians, statisticians and data scientists on the International Mathematics and Statistical Research Collaboration with Mongolia, which has been covered by several grants, including three sessions of GCRF funding from EPSRC. In 2019, the SAMBa EPSRC funding was renewed for a further five years. During the 2020 pandemic lockdown, I initiated the One World Seminar project with Leif Doering. From August 2020, I took up the role of director of the Institute for Mathematical Innovation
