 ACL Paper: A paper on semantic graph parsing was accepted at ACL 2018, to be presented this summer in Melbourne. The paper is AMR dependency parsing with a typed semantic algebra by Jonas Groschwitz, Matthias Lindemann, me, Mark Johnson and Alexander Koller.
 Oslo workshop on universal dependency parsing: March 1922 I attended a workshop at the Oslo Center for Advanced Study (CAS) to discuss semantic enhancements for Univeral Dependencies. We ( Jonas Groschwitz, Alexander Koller, and I) presented our AMalgebra and its dependency parser for AMRs, and met a bunch of interesting researchers.
 IWCS Paper: On Sept 20, 2017, Jonas Groschwitz presented joint work with me, Alexander Koller, and Marc Johnson at IWCS on a constrainted algebra for AMRs. AMRs can be decomposed with an sgraph algebra such as the HR algebra of Courcelle, but, for example, a graph with 5 nodes has an average of 10^{17} different ways it could be built. The HR algebra therefore needs to be constrained to make it useable. Previous work constrains it in an adhoc manner; our ApplyModify Algebra uses wellunderstood principles of semantic composition to constrain it in a way that keeps the linguistically reasonable derivations. The ApplyModify algebra finds an average of only 21 terms for a 5node graph.
 Degree awarded: Sept 15, 2017: I have a PhD!
 TAG+ Paper and presentation: On Sept 4, 2017 I presented a joint paper with Alexander Koller at TAG+13 on Minimalist parsing. We show how an MG can be encoded into an Interpreted Regular Tree Grammar, and use the encoding to show that the parsing complexity is much lower than previously thought, at O(n^{2lic+3}2lic)
 Software release: We're almost ready to release a new version of Alto, software for working with interpreted regular tree grammars. The new one will include Minimalist Grammars. You can email me for an advance copy

 In 2007 I spoke at my first conference, an undergraduate
conference called McGill's Canadian Conference for Linguistics
Undergrads (McCCLU I). Michelle St Amour and I edited the
proceedings, which seem to have disappeared off the web, so I'll put
them here: McCCLU I

 I'm working on a project on birdsong with
biologist Charles Taylor, linguist Ed Stabler, and neuroscientist Floris van Vugt. We believe some
birds, like the California Thrasher, must use a complex, even
humanlike grammar to produce their songs. I'm working primarily as a programmer to help show this must be the case.
