About
I am motivated by problems where clean theoretical ideas can be tested against realistic physical systems, especially when topology or collective dynamics reveals new behavior. I approach research by moving between first-principles modeling and numerics to connect abstract structure with experimentally meaningful predictions.
Current focus: building models for topological phases and magnonic platforms that clarify transport, coupling, and nonequilibrium dynamics.
Next: beginning doctoral research that unifies condensed matter theory, quantum information, and open quantum systems.
Experience highlights
- SUPREME REU at MIT (Luqiao Liu): magnonic spin-wave simulations, cavity-magnon coupling, and parametric down-conversion.
- Topological Condensed Matter Theory (Junyeong Ahn): Stiefel-Whitney phases, nodal-line systems, and Kubo conductivity calculations.
