Alexi Quintana Mathé

Alexi is a 6th PhD candidate working with David Lazer. His research focuses on social networks, both offline and online, through the analysis of social media and survey data. Alexi's dissertation work uses computational and statistical methods to study homophily for different types of social relationships from a sociological perspective. Broadly speaking, he is interested in understanding how structural and contextual factors lead to more or less divided networks. In addition, his research spans other diverse topics, such as online behavior,  the potential of large-scale non-probability surveys, and the evolution of social support through the COVID-19 pandemic. Alexi received a bachelor's degree in mathematics from the Polytechnic University of Catalonia (UPC) and a bachelor's degree in Sociology from the University of Barcelona (UB), and worked for two years in the private sector before starting his PhD.
