Research Interests

My main research interest is combinatorial commutative algebra with a focus on free resolutions of monomial ideals, and toric ideals. I am also interested in connections to algebraic geometry and tropical geometry.

  • "Finite atomic lattices and resolutions of monomial ideals", preprint, arXiv:1009.1430v1.
  • "Finite atomic lattices and their relationship to resolutions of monomial ideals", Ph.D. Thesis, Columbia University, May 2009.
