Research Summary

Mohamed Elmi studies Calabi-Yau geometry, mirror symmetry, and arithmetic structures that arise in string compactification. His recent work on periods of Calabi-Yau threefolds, Hulek-Verrill geometries, classically modular points, and Hadamard products treats period data as a bridge between algebraic geometry, BPS structures, and string-theoretic invariants. Related work on time reversal and CP invariance in Calabi-Yau compactifications shows how these geometric and arithmetic structures feed into physical questions about symmetries of compactified string theory.
