Hi there!
As of January 2024, I'm a postdoctoral researcher at the Department of Mathematics and Statistics, University of Jyväskylä, Finland.
My research is centered in fractal geometry and geometric measure theory. My current research interests include
Geometric and arithmetic properties of self-similar and self-affine sets and measures, such as
Dimension of orthogonal projections
Dimension of pairwise convolutions
Fourier decay
Existence of (affine/bi-Lipschitz/quasisymmetric) embeddings from one to another
and to what extent these properties are determined by algebraic or arithmetic properties of the defining contractions
The local structure of dynamically defined measures (e.g. ergodic measures on self-similar/self-affine sets)
And more recently, incidence estimates between points and lines/circles/other curves, and the dimension of Furstenberg-type sets.
Past associations
I obtained my PhD from the University of Oulu in 2023, where I worked as a doctoral researcher from 2019.
