My GitHub repositories include the following projects:

MultilineQueues: A compendium of iPython Notebooks with the implementation of the classes of fermionic and bosonic (called Multiline Diagrams before...) multiline queues (MLQs and MLDs) , Generalized MLQs, Supersymmetric MLQs, and Poset MLQs.
DilatedSimplices: In preparation.
LPMsRank2: An implementation of Python code to compute the h*-vector of the matroid base polytope of lattice path matroids from the dual graph of their (alcoved) triangulation. Explicit calculation for the case of Schubert matroids of rank 2 are included.
RandomProblemGenerator: A part of a project at Universidad de los Andes to automatize the generation of problem sets in Probability.
Physics-Undergraduate-Thesis: Includes the code in C++ used to generate the data to explore a particle model and the interactions between its phase transitions and chaotic parameters of the underlying dynamical systtem.
