Yanitza Cruz Crespo has broad interests in social influence, activism, disaster communication, and health communication. She is particularly interested in how social media users can influence others and their decisions, and what strategies they use to achieve it. Yanitza’s previous work analyzed tweets to inquire on how users coordinated actions and what strategies they used to mobilize others to protest offline and online during a political crisis. She is also interested in how activism takes place in colonized territories such as Puerto Rico and how social media could shape how Puerto Ricans are involved in politics.
