I am a research fellow working in arithmetic geometry. More precisely, I work on p-adic cohomology, p-adic Hodge theory and applications to mixed/positive characteristic geometry. 

Papers and preprints:

- O. Gregory, Torsion codimension 2 cycles on supersingular abelian varieties, to appear in the Canadian Math. Bull.

- O. Gregory, A. Langer, Motivic cohomology of semistable varieties, submitted.

- O. Gregory, A. Langer, Hodge-Witt decomposition of relative crystalline cohomology, submitted.

- O. Gregory, Crystals of relative displays and Calabi-Yau threefolds, J. Number Theory, 237 (2022), 257-284.

Other writing:

Here is my 2014 Cambridge Part III essay, Higher regulators of number fields, written under the supervision of Tony Scholl. It is an exposition of A. Borel's Cohomology de SL(n) et valeurs de fonctions zeta aux points entiers, Ann. Sc. Norm. Super. Pisa 4 (1977).
