Summary
Joint experiment–theory study showing that chemical-expansion-driven biaxial
strain in thin-film SrFeO₃ controls the helimagnetic ground state — a route
to engineer complex magnetic textures at the device scale.

I develop predictive theories of condensed matter materials and propose them for experimentalists to make. My work pairs first-principles calculations with symmetry analysis to discover new classes of materials with interesting electronic and magnetic properties. Specific material class of interests include semicondcutors and ferroic materials. My recent interest extends to integrating these methods into agentic workflows to accelerate materials discovery.
I moved to Evanston in May 2023 to join the Rondinelli Group at Northwestern University as a research associate.
