Research Interests
I am interested in how children induce linguistic structure from data. There are two parts to this ques-
tion: what assumptions about grammatical form do children implicitly make (i.e., what are their learning
biases), and what is the evidence they rely on? I use structured probabilistic models to quantify how well,
and in what ways, different kinds of evidence disambiguate various grammatical forms. In previous and
current work, I have looked at how acoustic cues, such as word duration, might provide useful evidence
for identifying syntactic structure. I plan to start using such models to evaluate how well different as-
sumptions about morphosyntactic abstraction match child language comprehension and production. I am
also interested in expanding my research program to include laboratory experiments that follow up on
computational results.

Software
All of these software packages can be freely accessed from my website under Free and Open Source
Software licenses. All the Scala code is parallelized across cores.
PredictabilityParsing, an implementation of the Dependency Model with Valence in Scala, including:
Expectation-Maximization for Maximum-Likelihood estimates.
Both the original O(n5) formulation and the O(n3) formulation using the “Fold-Unfold” transform.
Mean-field Variational Bayes for Bayesian estimates.
Interpolated backoff to learn from two observations per time step.
ProsodicParsing, an implementation of Hidden Markov Model-based unsupervised syntactic chunkers
in Scala.
Provides standard HMMs, HMMs with two observations per time step, and Coupled HMMs.
Based on a modified version of GRaphical Models in Mallet (GRMM).
modelselect.R, a model selection algorithm in R, written with Moreno Coco, for finding a mixed
effects model that is both tractable and well-controlled.
ShakesEM, an implementation of the Inside-Outside algorithm for binary branching PCFGs.
Contains an implementation of Inside-Outside for unlabeled but partially bracketed training data.
Miscellaneous bug fixes and feature enhancements to GRMM, Fluxbox, vim-latex-box, and other
FOSS projects.
Programming Languages
Proficient with several programming languages, including Scala, Java, Perl, R, Python, and Bash.
