Summary
Report of a record‑high 363% TMR at room temperature and current‑induced switching at ~10 MA/cm² in fabricated nanoscale PtMn₃|MgO|PtMn₃ junctions. Theoretical and computational basis for octupole-driven spin-transfer-torque switching in all-antiferromagnetic tunnel junctions.

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.
