Can you tell us a little bit about your background and career to date, as well as a few highlights?
I was born in Wallonia, Belgium, where I lived and studied until the age of 26. I attended Mons University to study Mathematics, initially intending to become a teacher. However, in my third undergraduate year, a course on Mathematical Methods of Physics—essentially a Group Theory course focused on applications in particle physics—sparked my passion for research and set me on the path to pursue a PhD.
After completing my doctorate, I stayed in Mons for my first postdoctoral position. During this time, I had the privilege of visiting the European Organization for Nuclear Research (CERN) for extended periods, where I began studying string theory "from scratch" under François Englert – a Belgian theoretical physicist who was later awarded the Nobel Prize for Physics in 2012, alongside Peter Higgs, for the discovery of the Brout-Englert-Higgs mechanism. François became both a collaborator and a dear friend.
Following my time in Mons, I spent a year at the École Normale Supérieure in Paris, where I wrote several papers that, two decades later, contributed to the discovery of Mathieu Moonshine, an area that continues to inspire my research today. From Paris, I moved to CERN for two years, where I met my husband, before heading to the University of Chicago for a few memorable years, during which my first child was born. Our family was fortunate to solve the "two-body problem" at Durham University, where I spent 33 years.
My career there evolved from being a full-time researcher to Lecturer, Reader, and eventually Professor. From January 2014 to December 2018, I served as Head of the Department of Mathematical Sciences, an experience unlike any before. Through determination and teamwork, we convinced university leadership to replace our outdated 1960s mathematics building.
This effort culminated in the design of a new facility, shared with Computer Science, in 2017, with construction beginning in 2018. This period also marked a breathtaking expansion of the department, as our staff numbers doubled within just four years. Reflecting on this transformative chapter, I am deeply proud of the collective achievements and the legacy of growth and renewal that will benefit future generations.
