About

I am an Assistant Professor of Linguistics at San Jose State University, where I teach courses on general and computational linguistics. My work generally concerns the mathematics of human language and learning. These cognitive feats emerge from humans' unique neuronal structure and computing power, allowing linguistic insight to contribute to the broader cognitive sciences and artificial intelligence.

Typology Emerges from Simplicity in Representations and Learning

We derive the well-studied subregular classes of formal languages, which computationally characterize natural language typology, purely from the perspective of algorithmic learning problems.

Computational Restrictions on Iterative Prosodic Processes

We formalize various iterative prosodic processes including stress, syllabification and epenthesis using logical graph transductions, showing that the necessary use of fixed point operators without quantification restricts them to a structured subclass of subsequential functions.

Probing RNN Encoder-Decoder Generalization of Subregular Functions using Reduplication

We analyze the expressivity of a variety of recurrent encoder-decoder networks, showing they are limited to learning subsequential functions, and connecting RNNs with attention mechanisms to a class of deterministic 2-way transducers.

Quantified Sentences as a Window into Prediction and Priming: An ERP Study

We used event related potentials (ERPs) to examine the processing of quantified sentences in an auditory/visual truth value judgment task, specifically to probe truth value and quantifier type influences on the N400 and ERP markers of quantifier complexity.
