Presenting CatLLM at the University of Washington

3 minute read

Published:

On October 29th, 2025, I had the privilege of presenting at the University of Washington on how large language models can augment social science research. The presentation focused on CatLLM, an open-source Python package I developed to address a common challenge in demographic and social science research: analyzing open-ended survey responses and complex data at scale.

On July 1st, 2025, I had the opportunity to present joint research with Dr. William H. Dow, Professor of Health Policy and Management and Director of the Center on the Economics and Demography of Aging at UC Berkeley. Our presentation explored a fascinating contradiction in Hispanic aging: the Hispanic health paradox in cognitive outcomes.

I recently presented my research at the Science Envoy “Ask a Science Envoy” event at HopMonk Tavern in Novato—my first time presenting at a brewery and to a non-academic audience. The experience taught me the importance of navigating sensitive topics like partisanship and belief in science, especially when audience members began debating the subject.

Understanding the Three-Group SIR Step by Step

16 minute read

Published:

In our upcoming paper, “Measuring and Modeling the Impact of Partisan Differences in Health Behaviors on COVID-19 Dynamics,” we use a three-group Susceptible-Infected-Recovered model to highlight the importance of incorporating partisan differences into models of disease transmission. In this blog post, I want to fully explain what is happening in the background for readers who may be interested in utlizing it themselves. For those users, we also built an R shiny app (soon to be published as well). The link to the shiny app will be: here.

Presenting our Research for the Center for Studies in Demography & Ecology at University of Washington, Seattle

1 minute read

Published:

The impact of non-pharmaceutical interventions and protective health behaviors, such as the use of face masks and physical distancing, on COVID-19 dynamics is well-documented, but sub-group heterogeneities in the adoption of these behaviors remains understudied. In this paper, we describe partisan differences in the adoption of protective health behaviors, and model how these differences can impact the dynamics of COVID-19.

How to Improve Match Quality on String Data Using Large Language Models

19 minute read

Published:

In the world of data analysis, ensuring the accuracy and consistency of datasets is crucial, especially when dealing with entities like school names that may be spelled differently across various sources. This discrepancy can pose significant challenges when trying to match records from different datasets. Traditional methods of data cleaning may fall short in addressing these inconsistencies effectively.

First Post in Honor of My Little Man, Charlie

This first ever blog post is in honor of my recently passed little man, Charlie the cat, who for 12 years went together with me through thick and thin. He was the best cat anyone could’ve asked for, and no other will ever be able to replace him. I will miss you dearly, Charles, aka “Chester.” I love you always.

Assessing the 10/66 Dementia Classification Algorithm for International Comparative Analyses with the U.S.

Published in American Journal of Epidemiology, 2025

Cross-national comparisons of dementia prevalence are essential for identifying unique determinants and cultural-specific risk factors, but methodological differences in dementia classification across countries hinder global comparisons. This study maps the 10/66 algorithm for dementia classification, widely used and validated in low- and middle-income countries (LMICs), to the U.S. Aging, Demographics, and Memory Study (ADAMS), the dementia sub-study of the Health and Retirement Study, and assesses its performance in ADAMS.

Father Connection & Support in Adulthood (UC Berkeley Social Networks Study)

Published:

Despite rapidly expanding interest in fathers, scholars know little about the impact of fathers on adult health and well-being. How does the positive presence – or lack thereof - of fathers in adult children’s lives affect their social networks? Drawing on attachment theory and social capital theory to examine novel UC Berkeley Social Networks Study (UC Nets) data, I seek to extend understanding of how father attachment and socialization can influence adult social well-being. I find that individuals who name a father in their social network have significantly more social ties. Those with a “close” father have larger social networks than those who name a father who is not “close.” This has consequences for individuals’ broader networks: respondents with a “close” father report more males – but not females – in social activities networks. In contrast, having a “close” mother was associated with more females to confide in, but not males.

Partisan Context and Its Associations on Individual Behavior During the COVID-19 Pandemic

Published:

Joint presentation with Dr. Audrey Dorélien examining partisan differences in the adoption of protective health behaviors during COVID-19 and modeling how these differences impact disease dynamics. Using detailed survey data on partisanship, contact rates, mask usage, and vaccination rates, we demonstrated that partisan differences in health behaviors exceed racial and gender differences. We incorporated these observations into a Susceptible-Infected-Recovered (SIR) model framework that explicitly incorporates partisanship to identify the most significant mechanisms driving disease spread, emphasizing the importance of considering partisan identification in public health policy and pandemic preparedness.

Partisan-Influenced Health Outcomes

Published:

Radio interview as a Wonderfest Science Envoy on KPOO’s “Let Me Touch Your Mind” show, hosted by Marilynn Fowler. Discussed research on partisan-influenced health outcomes and how political partisanship shapes public health behaviors and disease spread.

Partisan Differences in the Spread of Disease

Published:

Presented as a Wonderfest “Science Envoy” at a public science event co-hosted with Marin Science Seminar. The talk explored how political partisanship significantly influences how different groups respond to public health guidance, affecting their adherence to protective measures against infectious diseases. Understanding partisan-based disparities in acceptance of scientific evidence helps us to predict the population-wide spread of diseases and to improve public health outcomes.

Benefits and Challenges of AI in Demography

Published:

Participated in a panel discussion on the benefits and challenges of AI in demography at the 2025 PAA Annual Meeting. Discussed use-cases and benefits/limitations of large language models (LLMs) for survey research alongside other panelists.

Hispanic Migrant Cognitive Aging

Published:

Joint presentation with Dr. William H. Dow examining the Hispanic health paradox in cognitive aging. The talk explored the contradiction in Hispanic aging where Mexican migrants, despite being more socioeconomically disadvantaged, demonstrate better cognitive aging outcomes than other Hispanic migrant groups. This research contributes to understanding health disparities and the complex relationship between socioeconomic status and health outcomes in aging populations.

CatLLM: Augmenting Social Science Research with Large Language Models

Published:

Presented on computational tools that augment social science research using large language models. Introduced CatLLM—an open-source Python package that enables researchers to apply language and vision models to survey coding, image analysis, and data categorization without machine learning expertise. The talk covered practical applications in demographic research, including automated coding of open-ended survey responses and analysis of cognitive health data.
