Rate My Professor Alexandru Ghitza

Ghitza's scholarly contributions are evidenced by numerous publications in leading journals. Recent works include 'The non-existence of some Galois representations of moderate degree in small characteristic' (preprint, August 2025, with T. Yamauchi), 'Automorphy of mod 2 Galois representations associated to certain genus 2 curves over totally real fields' (Journal de Théorie des Nombres de Bordeaux, 2024, with T. Yamauchi), 'Elementary symmetric functions and deep power-sum congruences' (Integers, 2024, with S. Anni and A. Medvedovsky), 'Effective computation of Kurihara numbers' (RIMS Kôkûyroku Bessatsu B86, 2021), and 'Differential operators mod p: analytic continuation and consequences' (Algebra and Number Theory, 2021, with E. Eischen, M. Flander, E. Mantovan, and A. McAndrew). Earlier publications feature 'Some modular abelian surfaces' (Mathematics of Computation, 2020, with F. Calegari and S. Chidambaram) and experimental evidence supporting Maeda's conjecture on modular forms (with A. McAndrew, 2012). Ghitza has supervised PhD students, including those working on Galois representations and isogeny graphs. He co-organized the 2020 Number Theory Down Under meeting with Chenyan Wu and co-taught a short course on Galois representations and modular forms at the Introduction to SAGA research school in Luminy in 2023 with Anna Medvedovsky. His computational approaches have advanced understanding in modular forms and Galois representations.
