Overview
My research agenda serves to explore impactful questions concerning the role of the judicial branch in the American political system, the motivations and subsequent effects of judicial decision-making, and the emerging methodological tools of computational social science - particularly in the realms of natural language processing, data analysis and visualization, and machine learning models. I provide a brief overview of my active research in these fields below, much of which more recently has served to bridge my interests in judicial politics and computational methods.

How to Train Your Stochastic Parrot: Large Language Models for Political Texts
Co-Authored with Dr. Joseph Ornstein (University of Georgia) and Elise Blasingame (University of Georgia)
Large language models pre-trained on massive corpora of text from the Internet have transformed the way that computer scientists approach natural language processing over the past five years. But these “foundation models” have yet to see widespread adoption in the social sciences, partly due to their novelty and upfront costs. In this paper, we demonstrate that such models can be effectively applied to a wide variety of text-as-data tasks in political science–including sentiment analysis, ideological scaling, and topic modeling. In a series of pre-registered analyses, this approach outperforms conventional supervised learning methods without the need for extensive data pre-processing or large sets of labeled training data. And performance is comparable to expert and crowd-coding methods at a fraction of the cost. We explore the accuracy-cost tradeoff associated with adding more model parameters, and discuss how best to adapt and validate the models for particular applications.
