My area of interest is geometric measure theory. More precisely, I focus on quantitative aspects of rectifiability. Also, geometric problems from harmonic analysis, for example boundedness of singular integral operators on non-smooth sets.

Preprints

●   Ricci curvature lower bounds and uniform rectifiability

Joint work with M. Hyde and I.Y. Violo. arXiv preprint (2023).

●   Carleson's $\varepsilon^2$ conjecture in higher dimensions.

Joint work with I. Fleschler and X. Tolsa. arXiv preprint (2023).

●   Quantitative differentiability on uniformly rectifiable sets and applications to Sobolev trace theorems.

With J. Azzam and M. Mourgoglou. arXiv preprint (2023).

●   Faber-Krahn inequalities, the Alt-Caffarelli-Friedman formula, and Carleson's $\varepsilon^2$ conjecture in higher dimensions

Joint with I. Fleschler and X. Tolsa . arXiv preprint (2023).

●   Cone and paraboloid points of arbitrary subsets of Euclidean space

Joint with M. Hyde. arXiv preprint (2021). Warning! There is an error in the proof of the $C^{1,\alpha}$ result. The cone point result is correct. We hope to fix this soon.

●   Higher dimensional Jordan curves.

arXiv preprint (2020). Note: this was part of my PhD thesis. However I struggled to publish it because it has been misunderstood (poor boy). One criticism was good though: that the notion of "higher dimensional curve" is not sufficiently developed. I'm hoping to just do that as soon as I will find the time.
