Research - the questions that guide us 

I study the behavior of families of algebro-geometric objects and the structure of the spaces that parametrize them. Within this context, my work has three primary focuses: 

Next, I list my work, accepted articles (A) and submitted preprints (P), in such areas.

Computational aspects 

A4) Enumeration of max-pooling responses with generalized permutohedra . Laura Escobar, Javier González-Anaya, José L. González, Guido Montúfar, Alejandro H. Morales. To appear in Annals of Combinatorics.

A3) Quivers and moduli of their thin sincere representations in Macaulay2   with Mary Barker, we developed a Macaulay2 package called ThinSincereQuivers,  which describes the geometry and moduli spaces of thin-sincere representations of acyclic quivers, i.e., the dimension vector is all equal to one. To appear in the Journal of Software for Algebra and Geometry.

A2) Computation of GIT quotients of semisimple groups with Jesus Martinez-Garcia, Han-Bom Moon, and David Swinarski. To appear in the journal Mathematics of Computation by the AMS.

A1) VGIT for pairs, a computational approach (with J. Martinez-Garcia). Proceedings of the American Mathematical Society, 146(6), 2395-2408.  We also wrote a package in Python called Variations of GIT quotients. It calculates the computational information required to describe the GIT quotients, parametrizing a pair defined by a hypersurface and a hyperplane.
