Publications:

Local Euler obstructions of toric varieties To appear in Journal of Pure and Applied Algebra.

ArXiv preprints:

Polar degrees and closest points in codimension two with Martin Helmer.

Secants, bitangents, and their congruences with Kathlen Kohn and Paolo Tripoli.

Macaulay2 code

Toric Vector Bundles

Macaulay2 code I wrote for computing parliaments of polytopes of toric vector bundles:
A package Parliament.m2: Parliament.m2
Examples from Di Rocco-Jabbusch-Smith's article illustrating its use: examplesParliament.m2

Local Euler obstructions of WPS

Macaulay2 code I wrote for computing local Euler obstructions and degrees of dual varieties for weighted projective surfaces and threefolds.
A package EulerObstructionWPS.m2: EulerObstructionWPS.m2
