About me
I am a currently a Ph.D. student at TU Wien in the group Multiscale Calculus of Variations led by Elisa Davoli.
I enjoy the joint supervision of Elisa Davoli (TU Wien) and Giovanni Di Fratta (Università degli Studi di Napoli).
I am associated to the FWF project Analysis and modeling of magnetic Skyrmions led by Giovanni Di Fratta.
Research interests
At the moment my research focuses on:
Variational analysis of micromagnetic Skyrmions
Multiscale homogenization of heterogeneous and high contrast materials in micromagnetics, local and non-local
Poincaré inequalities in variable Sobolev spaces

"Nach meinem Urteil ist das größte Verdienst des Forschers, Dasein zu enthüllen, und zu offenbaren. Erklärung ist ihm Mittel, Weg zum Ziel, nächster - niemals letzter Zweck. Sein letzter Zweck ist, was sich nicht erklären lässt: Das Unauflösliche, Unmittelbare, Einfache."
- Friedrich Heinrich Jacobi
