About ANA

The Argumentation Network of the Americas

The Argumentation Network of the Americas aims to unite, sustain, and grow the community of argumentation scholars across the Americas.

Our Story

ANA began when two recent PhD graduates, faced with finding their place in the North American job market, recognized the need for organized and sustained support. 

ANA's mission is to provide a network to connect the interdisciplinary argumentation studies community across North, Central, and South America with a specific aim to support students and early career researchers. This will be done through a periodic major conference, along with smaller regional events taking place more regularly. The main priority of the ANA executive is to make connections across the continents in efforts to support the the growth and development of researchers in the field.
