My research aims to understand and control the behavior of two-dimensional (2D) materials, with a particular focus on the materials physics of atomically thin semiconductors. These 2D van der Waals (vdW) heterostructures offer unique structural tunability, enabling precise control over their electronic and optical properties. Building on my recent work involving crystal symmetry engineering, bilayer Wigner crystals, and the discovery of electronic microemulsion phases near the Wigner crystal-to-liquid transition in transition metal dichalcogenides (TMDs), I plan to further explore and manipulate emergent phenomena driven by strong electron and exciton interactions in 2D systems—with the goal of advancing platforms for next-generation optoelectronic devices and quantum information technologies.
