Research Interests

My interests lie at the intersection of politics and communication, with a focus on the influence of digital tools on individual and mass political behavior. This includes exploring new forms of communication and behavior that emerge from the digital environment, as well as examining how previously studied phenomena manifest differently in new venues. In my projects, I employ a combination of both qualitative and quantitative tools, with a focus on experimental and survey methods.

Who Gets Fact-Checked? Attention Gaps in PolitiFact’s Coverage to U.S. Legislators

Are fact-checking agencies more likely to cover statements made by individuals of certain demographic backgrounds? Previous studies suggest that politicians from underrepresented groups tend to receive less attention from traditional media, but no research has explored this possibility in fact-checking journalism. I analyze how PolitiFact covered statements from members of Congress between 2007 and 2022. The results suggest that legislators from panethnic groups receive less attention, even though their statements more often meet the fact-checker's standards of what should be covered.

The Language of Truth: How Lexical Choices Influence Fact-Checking Reception

People who support outsider or anti-establishment political leaders tend to believe and share misinformation more often, yet they are the least likely to trust or engage with fact-checkers. This mixed-methods project aims to identify specific aspects of factual corrections that might turn these groups away. I show through observational data that online fact-checkers use linguistic markers that are less morally charged and more associated with a liberal identity than other media outlets, even those considered liberal. I propose a survey experiment to test whether changes in these linguistic features can increase acceptance of corrections and trust in fact-checking among skeptical audiences.

Campaign Negativity and Political Participation in the Social Media Era

(With Asahi Obata and Randy Stevenson) Do negative political campaigns lead to lower political participation? We revisit this question in the current era of multiple social and media platforms. While several studies have explored whether negative campaigns on traditional media lead to demobilization, we argue that this relationship is conditional on the media voters see negative campaigning on. We test this through the first immersive artefactual field experiment in the study of social media platforms.

Teaching Assistant

I have worked as a TA for undergraduate-level classes on American and Comparative Politics, both in English and Spanish, and for graduate-level courses on statistics and quantitative methods. I have experience leading discussion sections and evaluating students’ performance through assignments and exams. In 2024, I completed Rice's Graduate Certificate in Teaching and Learning.

My teaching style privileges active engagement and dynamic learning experiences. I prefer a discussion-based approach whenever possible. I also place significant emphasis on the use of multimedia in the classroom to enhance comprehension and prepare students to navigate a multimedia-rich information landscape.

Reviews From Students

Agustin was amazing. He gave excellent feedback on papers, graded very fairly, and drove discussions forward with compelling and interesting slideshows.

We had a lot of fun debates, questions, and ideas in our section -- making it the highlight of the entire class for me, due in large part to Agustin's energy, poise, experience, and guidance.

He was a great TA and discussion leader, and always provided opportunities for each student to share their thoughts in class.
