Research
The $K$-theory of the moduli stacks $\mathcal{M}_2$ and $\overline{\mathcal{M}}_2$ (joint with Dan Edidin). To appear at manuscripta mathematica. Journal.
We compute the integral Grothendieck rings of the moduli stacks of smooth and stable genus two curves respectively, and show that they are both free abelian.
The integral Chow rings of the stacks of hyperelliptic Weierstrass points (joint with Dan Edidin). To appear at Michigan Mathematical Journal. M2 codes (work-in-progress).
We compute the integral Chow rings of the stacks parametrizing hyperelliptic curves with n marked Weierstrass points. We proved that the integral Chow rings of each of these stacks is generated as an algebra by any of the psi-classes and that all relations live in degree one.
Chow classes of divisors on stacks of pointed hyperelliptic curves (joint with Dan Edidin). Ann. Sc. Norm. Super. Pisa Cl. Sci. (5) 25 (2024), no.1, 217–240. Journal.
We calculate the Chow classes of the universal hyperelliptic Weierstrass divisor and the universal g^1_2 divisor with expressions in terms of bases of their associated divisor class groups.
