Research

I focus on emergent quantum phenomena in correlated systems. I primarily research superconducting materials, especially at interfaces with other quantum systems, such as semiconductors, magnets, or topological materials.

Interfaces are inherently rich and complex regions, both physically and conceptually. The principle that we measure relative differences, not absolutes, makes interfaces a natural place to look for novel phenomena, such as exotic quasiparticles and symmetry breaking, both in and out of equilibrium.

Beyond the intellectual appeal of discovering new physical phenomena and developing new theoretical tools, this field is especially exciting due to its potential technological impact. Systems with exotic quantum properties can lead to quantum devices with higher efficiency and enhanced quantum coherence and sensing capabilities.
