Damian Sawicki

I am a postdoc in the Analysis Group of Prof. Stefaan Vaes at the Department of Mathemathics of KU Leuven. Previously, for two years I was a visiting postdoctoral researcher in Max Planck Institute for Mathematics in Bonn. I did my PhD in 2018 under the supervision of Prof. Piotr W. Nowak at the Institute of Mathematics of the Polish Academy of Sciences (IMPAN).

My research interests lie within geometric and analytic group theory and metric geometry and their interactions with operator algebras, index theory, and dynamical systems. For more details, you can find my publication list below.

Apart from BSc, MSc, and PhD degrees in mathematics, I hold a BSc in computer science from the University of Warsaw, so I always gladly review for MathSciNet publications with an algorithmic flavour.

My co-authors include: Goulnara Arzhantseva from Vienna, Dawid Kielak from Oxford, Tim de Laat from Münster, William Geller and Michał Misiurewicz from Indianapolis, Kang Li from Erlangen, Massoud Amini and Ali Shakibazadeh from Teheran, Jianchao Wu from Shanghai, and Piotr Nowak from Warsaw.

I am not teaching at the moment. I had a purely research position at the MPIM, but taught during MSc and PhD studies:


You can find me at Google Scholar (which is the number one tool for tracing citations in the preprint era) and ORCID (assigning unique identifiers to researchers so that I am not confused with a computer scientist from Białystok with the same name and surname). I also recommend acquiring an arXiv author id, so that you can link to a website like this one instead of relying on the arXiv search feature. On websites MathSciNet (subscription only) and Zentralblatt (open access since 2021!) you can retrieve citation data of published works (their main goal is to provide author-independent reviews or summaries, which also happen to be very useful). At times, you can also find me at LinkedIn. I agree with the San Francisco Declaration on Research Assessment (DORA), even though I am aware that implementing these principles may be elusive.

You can find some more information (attended events, talks given, and slides or posters) from the period of my PhD studies on my old webpage.
