Muñoz's research and theory are centered in the ethnography of speaking based on fieldwork in Colombia, England, Spain, Finland, and Texas. Her current work centers around intercultural communication and persuasion and personal relationships in cultural context, particularly at the intersections of public discourse and interpersonal social interaction.

In spring 2015, she was the 17th Josephine B. Jones lecturer at CU-Boulder. Her talk, "Friendship and Romance: Silence, Stories and Secrets in Four Cultures," presented her ongoing work on the relationship between cultural/communal codes and relational codes and is now available online: https://vimeo.com/140580349
