About me

I am a Ph.D. candidate in the Department of Sociology at Cornell University and a member of Michael Macy’s Social Dynamics Laboratory. Next to my studies in sociology, I am pursuing a minor in the Department of Computer Science.

My Ph.D. committee consists of Michael Macy, Filiz Garip, Eleonora Patacchini, and Felix Elwert. I am a research assistant of Kelly Musick.

My research examines network and family dynamics as drivers of social inequality:

Together with Michael Macy, Eleonora Patacchini, and David Grusky, I study whether disadvantaged youth benefit from interacting with children from different socioeconomic backgrounds and whether such benefits depend on the overall network structure. This project has received a two-year NSF award.

Together with Kelly Musick, I examine how the changing impact of parenthood on earnings has reshaped earnings inequality in the last four decades. As part of this project, I am developing the R package “ineqx“, which allows linking aggregate-level changes in inequality more directly to changes at the individual level.

A second line of my research focuses on how complex dependencies among observations, such as spatial, multilevel, and network embeddedness, can be modeled within the regression framework:

Together with Weihua An and Roberson Beauville, I am writing an Annual Review of Sociology article on “Causality in Social Networks”.

I have developed the generalized multiple membership multilevel model, which is implemented in the R package “rmm“, to account for dependencies arising from the crisscrossing relationship between political parties and coalition governments in political science research on coalition government outcomes.
