About me
I am a mathematician, employed as an Adiunkt (Assistant Professor) at IM PAN, Warsaw, in the NCN Maestro Project Analysis on Groups of Piotr Nowak, and (for the summers of 2026 and 2027) as a Humboldt Fellow at Universität Regensburg, in the group of Clara Löh.Before that, I was a JSPS postdoctoral fellow at Kyōto University, working with Kōji Fujiwara. I completed my PhD at the University of Cambridge in 2024, under the supervision of Henry Wilton. My research is in geometric group theory, a field concerned with understanding groups — algebraic structures encoding the symmetries of mathematical objects — by studying their actions on geometric spaces. I am generally interested in understanding connections between group-theoretical structure and non-positive curvature. Here is a poster explaining my research on stable commutator length.
Together with Piotr Nowak, Mark Pengitore, and Arturo Espinosa Baro, I am organising the Analytic and geometric group theory seminar at IM PAN. Please feel free to send me an email if you would like to give a talk!

Statement on large language models
Considering the role of large language models in aggravating the climate crisis, considering the harm they can produce in mathematics and human thought, and considering our responsibility as mathematicians, my personal choice is the following.
I will not (knowingly) use any large language model in my work and private life.
I will refuse to review papers making (significant) use of large language models, I will refuse to collaborate on projects using large language models, and I will not consent to any of my writing being fed to large language models. I will keep to this stance as long as large language models are based on the Earth- and human-damaging philosophy which is currently at their core.
My views on large language models are developed in the text Mathematicians, machines, and the Earth.
