I'm a postdoctoral researcher here at the University of Oxford, a Beecroft Fellow in Cosmology, and a Junior Research Fellow at Linacre College. Prior to this, I was a Fellow of the Carlsberg Foundation, also at Oxford, at the Rudolf Peierls Centre for Theoretical Physics, and a Postdoctoral Fellow of INRIA, Nancy, while based at Institut d'Astrophysique de Paris (IAP), France. I completed my PhD at The Niels Bohr Institute, University of Copenhagen, Denmark, in 2019.

In my research I aim to cover a broad range of topics within particle physics and cosmology. On that front, I study statistical and physical properties of the Cosmic Microwave Background and signals related to it, as well as patterns in the distributions of and kinematics of matter in the (comparably) local universe. While often data-driven, my research combines theoretical, methodological, and experimental aspects of cosmology. Feel free to read more about my and my collaborators’ work on my Research and Publications pages — or just send me a mail!

Apart from doing the actual research, I enjoy public engagement activities (and as part of my time here I got involved in activities, such as shown here).  Please don't hesitate to tell me about your outreach ideas; I'm happy to chat!
