Boundedness of the p-primary torsion of the Brauer group of products of varieties
Forum of Mathematics, SigmaLet k be a field finitely generated over its prime subfield. We prove that the quotient of the Brauer group of a product of varieties over k by the sum of the images of the Brauer groups of factors has finite exponent.

On the Brauer group of diagonal quartic surfaces [PDF]
Journal of the London Mathematical Society, 2011 We obtain an easy sufficient condition for the Brauer group of a diagonal quartic surface D over Q to be algebraic. We also give an upper bound for the order of the quotient of the Brauer group of D by the image of the Brauer group of Q.

Boundedness of the p-primary torsion of the Brauer group of an abelian variety [PDF]
Compositio Mathematica, 2022 We prove that the $p^\infty$-torsion of the transcendental Brauer group of an abelian variety over a finitely generated field of characteristic $p>0$ is bounded.

Contractions of hyper-Kähler fourfolds and the Brauer group [PDF]
Advances in Mathematics, 2021 We study the geometry of exceptional loci of birational contractions of hyper-K\"ahler fourfolds that are of K3$^{[2]}$-type. These loci are conic bundles over K3 surfaces and we determine their classes in the Brauer group. For this we use the results on

Evaluating the wild Brauer group [PDF]
Inventiones Mathematicae, 2020 Classifying elements of the Brauer group of a variety X $X$ over a p $p$ -adic field by the p $p$ -adic accuracy needed to evaluate them gives a filtration on Br X $\operatorname{Br}X$ . We relate this filtration to that defined by Kato’s Swan conductor.

The conjectures of Artin-Tate and Birch-Swinnerton-Dyer [PDF]
Épijournal de Géométrie Algébrique, 2022 We provide two proofs that the conjecture of Artin-Tate for a fibered surface is equivalent to the conjecture of Birch-Swinnerton-Dyer for the Jacobian of the generic fibre.

Patient and Caregiver Perceptions of Animal Assisted Activity in Orthodontics
Animals, 2022 Dental anxiety affects up to 21% of children and 80% of adults and is associated with lifelong dental avoidance. Animal assisted activity (AAA) is widely used to reduce anxiety and pain in medical settings and has promise in dentistry.

Brauer groups of moduli of hyperelliptic curves via cohomological invariants
Forum of Mathematics, Sigma, 2021 Using the theory of cohomological invariants for algebraic stacks, we compute the Brauer group of the moduli stack of hyperelliptic curves ${\mathcal {H}}_g$ over any field of characteristic $0$.
