Hlér Kristjánsson

***I have now left the Perimeter Institute and will be starting a group at Université de Montréal as Assistant Professor in the Department of Computer Science and Operations Research from January 2025. If you are interested in joining my group as a PhD or master's student in quantum information and foundations, or as a postdoc, please drop me an email!*** 

I am a joint postdoctoral research fellow in quantum foundations and quantum information at the Perimeter Institute and the Institute for Quantum Computing. I grew up in Akureyri, Iceland, and later in Cambridge, UK. I completed my undergraduate and masters' degree in Physics at Imperial College London, UK, in 2018 and did my masters' thesis at the University of Freiburg, Germany, on a one-year Erasmus exchange program, in the group of Prof Dr Andreas Buchleitner. I completed my PhD in Computer Science at the University of Oxford in 2022, under the supervision of Prof Giulio Chiribella and Prof Jonathan Barrett, with a few months as a visiting PhD student at the University of Hong Kong. In 2021, alongside my PhD, I worked as an independent research consultant in quantum communications for Ofcom, the UK Office for Communications. From 2022-23, I was a postdoctoral researcher at the University of Tokyo, in the group of Prof Mio Murao. 

In addition to science, I have also studied non-degree courses in violin performance as an Ash Music Scholar at the Royal College of Music, London, UK, in German language at the University of Freiburg, Germany, and in Chinese language as a Huayu Scholar at the National Kaohsiung Normal University, Taiwan. As a musician, I have co-composed and released an original album, and performed as a violinist at various venues. In my spare time, I like learning languages and cooking elaborate meals, as well as doing exercise and mindfulness meditation.
