Hossein Azarpanah is a Postdoctoral Fellow at the Centre for the Study of Democratic Institutions (CSDI) at the University of British Columbia. He holds a PhD in Business Administration from Concordia University, where he studied how social media discourse shapes public understanding and collective action during health crises. His research integrates computational methods such as topic modeling, sentiment analysis, and discourse analytics, with theories of social behavior to examine vaccine hesitancy, online polarization, and the dynamics of crisis communication. His broader research explores how digital communication platforms shape public discourse and influence collective behavior in polarized or crisis-driven contexts.
