I am a PhD student in David Chiang's natural language processing research group at the University of Notre Dame. My primary research focus is on incorporating simulations of nondeterministic pushdown automata into neural networks to improve machine learning on human languages. My interests lie generally in syntax, machine translation, and neural networks.

News

  • My paper with David Chiang, "Learning Context-Free Languages with Nondeterministic Stack RNNs", has been accepted to CoNLL 2020 and is now available on arXiv! The code is available on GitHub.
  • I've released an update to my semiring einsum package, a PyTorch package that allows you to do einsum in different semirings, with significant performance improvements and published it on PyPI. Just pip install torch-semiring-einsum!
  • I finished up a (remote) internship with the awesome Amazon Translate team in NYC. Thanks for a great summer!
