My aim is to identify and detect novel spatial structures in physics and mathematics. Therefore, I develop statistical and mathematical analysis tools to learn what geometry can tells us about the physical properties. Thus, my research combines surprising physical phenomena with rigorous mathematics and statistics.

Examples of my research

Disordered hyperuniformity: Hyperuniform patterns are isotropic and disordered (like a liquid) but have no long-range density fluctuations (like a crystal).
[ Nat. Commun. 2019 — Random Struc. Algorithms 2020 — Phys. Rev. X 2020 ]
Phoamtonics: We showed that it is possible to construct foam-based heterostructures with complete photonic band gaps that prohibit the propagation of electromagnetic waves in all directions.
[ PNAS 2019 ]
Photonic networks: When we optimized photonic band gaps of networks, we discovered a subtle, unanticipated universal behavior of both crystal and disordered networks.
[ Phys. Rev. Lett. 2021 ]
Morphometric data analysis: Our null hypothesis test detects structural deviations from background noise using Minkowski functionals. The additional shape information can dramatically increase the sensitivity of the test.
[ Astron. Astrophys. 2013 — Electron. J. Stat. 2018 — EPL 2019 ]
Shape analysis of nano-rough surfaces: An integral geometric data analysis can quantitatively predict how the experimentally measured bacterial adhesion forces change with an increasing nanoroughness of surfaces designed for medical implants.
