Research Interests

  • Quasirandomness
  • Spectral Hypergraph Theory
  • Discrete Geometry
  • Universal Cycles
  • Combinatorial Number Theory
  • Coding Theory
  • Extremal Graphs
  • Matrices over GF(2) and Graph Pressing
  • Applied Machine Learning
  • Permutation Patterns

Current Projects

  • Graph pressing sequences. We use matrix algebra over GF(2) to study graph-theoretic problems arising from computational phylogenetics: Can sortings-by-reversal be efficiently sampled? When are they unique? Are they highly connected by "small edits"?

  • Spectral hypergraph theory. We study the connection between the homogeneous spectra of hypermatrices/tensors (e.g., the adjacency hypermatrix and Laplacian) associated with hypergraphs and the properties of those hypergraphs, such as degree sequences, subgraph counts, k-partiteness, and connectivity.

  • CNNs in Biology. We apply modern image processing techniques (especially, deep convolutional neural networks) to perform classification and quantitation of cell phenotypes in microscopy performed during immunological/hematological experiments.
