I am Executive Dean of UniSA STEM, which includes Science, Technology, Engineering, and Mathematics at UniSA. Prior to starting at UniSA in July 2023 I was Executive Dean of Science at Durham University in the UK (2020-2023) and Head of the School of Mathematics and Statistics at the University of Sydney (2016-2019). I studied Mathematics at the University of Warwick in the UK. I moved to Australia and worked at the University of New South Wales and the University of Newcastle (Australia) before leading the reloaction of a team of four to the University of Wollongong in 2007. During my time at UOW I served two terms as Head of the School of Mathematics and Applied Statistics. 
My research interests include: pure mathematics, including algebra and analysis, usually with a geometric flavour; applications to electrical engineering; and applied statistics. My work during the covid pandemic had significant social impact, particularly in the UK. Essentially, it's partly my fault that people were self-administering covid tests, and I helped to get food back onto supermarket shelves in the UK in July 2021. I can tell you more about any or all of it if you really want to know details.
I serve the profession by working with Institutes, Research Councils, and Educational Authorities. I was instrumental in establishing the University of Sydney Mathematical Research Institute and am currently on the Scientific Committee of the Banff International Research Station. I have worked extensively with the Australian Research Council by serving on College of Experts (including as Chair of the Australian Laureate Fellowship Selection Advisory Committee), reviewing Centres of Excellence, and as a panel member on multiple Excellence in Research for Australia research assessment exercises. I am also an active community volunteer, working directly with schools and through the Australian Mathematical Sciences Institute and the Australian Mathematics Trust.
On a personal level, I was born in London into a family of Spanish immigrants. Consequently, I am lucky to have Spanish as my first language and English as my native language, which meant that I could work my way through university as an interpreter. I have 25 cousins on my mother's side, I was the first person in my extended family to go to university, and I know first-hand how education can transform your life.

My current research focuses on pure mathematics, specifically: operator algebras and related structures; and totally disconnected, locally compact groups.
