Conner Joyce
Conner Joyce is a PhD candidate in Political Science at Rice University with a focus on International Relations. His research interests include digital technology and international security. In particular, he studies how technology can facilitate the emergence of security threats from non-state actors and how state actors can cooperate to mitigate these threats. His work on these topics has been published in the Journal of Conflict Resolution. As a Research Fellow at the Center for Computational Insights on Inequality and Society at Rice, Conner examines how cybercriminals become politically motivated hackers. He shows that social connections among cybercriminals allow for the transmission of political and radical activities. To conduct this research, he leverages large-scale web scraping, large language models, machine learning (with deep transfer learning), and experimental designs. Conner holds an MA in Public Affairs from the University of Texas LBJ School of Public Affairs and a BA in Political Science from Southwestern University. Personal Website

Yunjie “Grace” XieYunjie “Grace” Xie is a third-year PhD student in Economics at Rice University. Her research interests span computational social science, development economics, labor economics, and public policy, with a focus on how social and institutional structures shape economic outcomes. As a Research Fellow at the Center for Computational Insights on Inequality and Society at Rice, Yunjie is developing a dynamic model of household labor supply and intergenerational childcare to study gender pension gaps in China. This project seeks to capture how childcare responsibilities and pension systems jointly influence women’s labor market participation, savings decisions, and long-term retirement security. Her research contributes to a deeper understanding of gender inequality in economic opportunities and outcomes. It also informs policies that promote more equitable labor and pension systems. Yunjie holds an MA in Economics from Columbia University and a BA in Economics from Renmin University of China. |

Caroline WolskiCaroline Wolski is a third-year PhD student in Sociology. Her research interests center on applying quantitative and computational methods to examine racial/ethnic disparities in health outcomes and access to health care. As a research fellow at the Center for Computational Insights on Inequality and Society at Rice, Caroline is developing her dissertation, which investigates how racial and spatial inequalities jointly structure access to health care in the United States. Her work emphasizes how the distribution, quality, and centralization of health care facilities shape persistent disparities for marginalized communities. The project combines national survey data, metropolitan-level functional clustering of health care infrastructure, and a spatial case study of Houston to reveal how racial residential segregation and centralized medical hubs restrict meaningful access to care. In addition, Caroline is coauthoring projects on neighborhood analysis of prenatal health care access and on computational methods for sociology. Her previous work includes analyses of COVID-19 mortality and vaccinations, racial/ethnic residential segregation, neighborhood health care provision, pediatric provider choice, and the distribution of health-related urban amenities. Caroline holds an MA in Sociology from the University of Houston and a BA in Sociology from the University of California, Davis. |

Shahill ParsonsShahill Parsons is a fourth-year PhD student in Sociology at Rice University. His research interests include race, racism, racial inequality, social stratification, mixed methods, and computational social science. His scholarship examines the lived experiences of African Americans at the nexus of race, racism, racial inequality, and social stratification, and the pathways and obstacles to racial equality across social and institutional domains via mixed-methods (e.g., quantitative, qualitative, computational social science). His research spans from examining law enforcement’s behavioral changes following high-profile encounters with Black individuals to theorizing how marginalized communities displaced by gentrification temporarily repurpose space. His work illustrates how these institutional dynamics that intersect with African American lived experiences both facilitate and hinder routes to racial equality. As a Research Fellow at the Center for Computational Insights on Inequality and Society at Rice, Shahill extends prior research on “racial cooling periods”—temporary decreases in police killings of Black individuals following high-profile incidents—by establishing causal relationships through quasi-experimental methods (e.g., synthetic controls). Shahill holds a BS in Sociology from Florida State University and an MA in Sociology from Rice University. |

Sho IzumisawaSho Izumisawa is a fourth-year PhD student in Political Science at Rice University with a focus on Comparative Politics and Political Methodology. His research interests include ideology and coalitions. As a Research Fellow at the Center for Computational Insights on Inequality and Society at Rice University, Sho examines how different types of elite data affect estimates of Japanese legislators’ ideological positions. He employs a range of data sources and estimation techniques, including large language models, to measure ideology. This research addresses an important question: to what extent do different data sources yield different estimates of the same legislators’ ideological positions? Sho holds a BA in International Relations from IE University in Spain. |
