I am a graduate mathematician specializing in spectral geometry, quantum graphs, and discrete transforms. Currently pursuing my Master's degree at Stockholm University, my research bridges topological connectivity modifications with operator theory.

Key Research Highlights
"Berry Phase for Quantum Graphs" (Supervised by P. Kurasov)
Proved that a complete cycle of topology change on a figure-eight metric graph induces a
non-trivial geometric Berry phase shift of exactly \(\pi\) for real-valued eigenfunctions.
