I am a postdoctoral researcher at the Department of Mathematics and Statistics at the University of Jyväskylä. I am mostly interested in geometric measure theory, as well as its applications to harmonic analysis and PDEs. I work in the Geometric Measure Theory group, led by Katrin Fässler and Tuomas Orponen.

In years 2022-2025 I am supported by the Academy of Finland postdoctoral grant *Quantitative rectifiability and harmonic measure beyond the Ahlfors-David-regular setting*, grant No. 347123.

I defended my PhD in February 2021 at the Universitat Autònoma de Barcelona, where I worked under supervision of Xavier Tolsa.

Interests

- quantitative rectifiability
- singular integral operators in non-doubling setting
- behaviour of sets and measures under orthogonal projections
- visibility problems
