About

Kenji Sagae is a computational linguist with research interests that include data-driven modeling of language phenomena, corpus methods, and application of language processing approaches to various forms of language analysis. His current work includes the application of neural models to analysis of syntax and semantics with linguistically expressive formalisms, and multilingual analysis of child language development. He received a PhD in language technologies from Carnegie Mellon University, and prior to joining UC Davis in 2016, he was a startup co-founder and a faculty member of the University of Southern California.

Research Focus

Computational linguistics and natural language processing, focusing on data-driven methods applied to analysis of syntactic and semantic structure.
