Andrea holds a PhD in Demography from the University of California, Berkeley. As of September 2024, she is an Economic Researcher at Banco de México (Central Bank of Mexico), specifically in the Directorate General of Economic Research. Her research focuses on Mexican emigration, primarily to the U.S., and how migrant characteristics have changed during this century.

Her dissertation explores the available data to study Mexican migration and focuses on differences by gender and by intentions to migrate. Specifically, she shows how the Mexican Labor Force Survey (ENOE) is a useful source to understand timely change in migration (in and out) in Mexico, since it complements existing statistics from the Mexican Census and other household surveys. Her second chapter adds to the literature on intentions to migrate by focusing on how preparing to migrate may be indicative of future migration. Finally, the third chapter discusses how migrant selection has changed between 2005-2020 and how an important component is gender, specifically in the discussion of feminization of migration.
